Description

Es wird ein Verfahren zur Lokalisierung von Lichtquellen angegeben. Darüber hinaus werden ein Computerprogramm, das zur Ausführung eines solchen Verfahrens eingerichtet ist, sowie eine Lokalisierungseinheit für ein solches Verfahren angegeben.A method for locating light sources is given. In addition, a computer program adapted to carry out such a method and a localization unit for such a method are provided.

In der Druckschrift US 7,495,671 B2 ist ein Beleuchtungsorganisationssystem angegeben.In the publication US Pat. No. 7,495,671 B2 a lighting organization system is indicated.

Eine zu lösende Aufgabe besteht darin, ein Verfahren anzugeben, mit dem für eine Mehrzahl von Lichtquellen einer Anordnung eine räumliche Zuordnung zu logischen Adressen automatisiert erfolgen kann.An object to be solved is to specify a method with which a spatial assignment to logical addresses can be automated for a plurality of light sources of an arrangement.

Gemäß zumindest einer Ausführungsform des Verfahrens dient dieses zur Lokalisierung von Lichtquellen einer Anordnung, wobei die Anordnung eine Mehrzahl von Lichtquellen umfasst. Lokalisieren bedeutet insbesondere, dass von einer Anordnung der Lichtquellen ein zweidimensionales oder dreidimensionales Abbild erstellt wird, wobei in dem Abbild die Lichtquellen der Anordnung bevorzugt entsprechend ihrer realen Position im Raum angeordnet und/oder erfasst sind und die Lichtquellen in dem Abbild über eine eindeutige Kennung oder Adresse identifizierbar sind. Mit anderen Worten kann Lokalisierung heißen, dass von der realen, dreidimensionalen Anordnung der Lichtquellen ein zweidimensionales oder dreidimensionales Modell erstellt wird. Das Modell, das insbesondere ein Computermodell ist, ist bevorzugt für eine gezielte Ansteuerung der Lichtquellen einsetzbar.According to at least one embodiment of the method, this serves for the localization of light sources of an arrangement, wherein the arrangement comprises a plurality of light sources. Localization means in particular that a two-dimensional or three-dimensional image is created by an arrangement of the light sources, wherein in the image the light sources of the arrangement are preferably arranged and / or detected according to their real position in space and the light sources in the image via a unique identifier or Address are identifiable. In other words, localization may mean that a two-dimensional or three-dimensional model of the real, three-dimensional arrangement of the light sources is created. The model, in particular a Computer model is, is preferably used for a targeted control of the light sources.

Gemäß zumindest einer Ausführungsform des Verfahrens handelt es sich bei den zu lokalisierenden Lichtquellen um Halbleiterlichtquellen wie Leuchtdioden oder Laserdioden. Bei den Lichtquellen kann es sich ausschließlich um Halbleiterlichtquellen handeln oder auch um eine Mischung aus Halbleiterlichtquellen und Hochdrucklampen, Halogenlampen, Glühlampen und/oder Leuchtstofflampen. Beispielsweise weist die Anordnung oder ein Teil der Anordnung, in dem die Lichtquellen zu lokalisieren sind, mehr als zehn Lichtquellen, bevorzugt mehr als 100 Lichtquellen oder mehr als 500 Lichtquellen oder mehr als 1000 Lichtquellen auf. Die Lichtquellen sind bevorzugt derart verschaltet, dass sie einzeln und unabhängig voneinander ansteuerbar sind. Ebenso können mehrere Lichtquellen jeweils zu einer Gruppe zusammengefasst sein, wobei einzelne Gruppen bevorzugt unabhängig voneinander ansteuerbar sind.In accordance with at least one embodiment of the method, the light sources to be located are semiconductor light sources such as light-emitting diodes or laser diodes. The light sources may be exclusively semiconductor light sources or else a mixture of semiconductor light sources and high-pressure lamps, halogen lamps, incandescent lamps and / or fluorescent lamps. For example, the arrangement or a part of the arrangement in which the light sources are to be located has more than ten light sources, preferably more than 100 light sources or more than 500 light sources or more than 1000 light sources. The light sources are preferably connected in such a way that they can be controlled individually and independently of each other. Likewise, a plurality of light sources can each be combined to form a group, wherein individual groups are preferably independently controllable.

Gemäß zumindest einer Ausführungsform des Verfahrens umfasst dieses den Schritt des Erstellens einer Liste der Lichtquellen der Anordnung oder des Teils der Anordnung. Jede der Lichtquellen weist hierbei eine eindeutige digitale Kennung oder Adresse, kurz ID oder unique ID, auf. Die digitale Kennung umfasst eine Bitsequenz. Beispielsweise weist die Kennung mindestens 16 Bit, bevorzugt mindestens 32 Bit oder mindestens 48 Bit auf. Es sind in der Liste alle zu lokalisierenden Lichtquellen und deren Kennung aufgeführt.In accordance with at least one embodiment of the method, this comprises the step of establishing a list of the light sources of the arrangement or of the part of the arrangement. Each of the light sources here has a unique digital identifier or address, short ID or unique ID. The digital identifier comprises a bit sequence. For example, the identifier has at least 16 bits, preferably at least 32 bits or at least 48 bits. All the light sources to be located and their identification are listed in the list.

Gemäß zumindest einer Ausführungsform des Verfahrens umfasst dieses den Schritt des zeitgleichen Ansteuerns der Lichtquellen, sodass jede der Lichtquellen eine Leuchtsequenz entsprechend der zu der jeweiligen Lichtquelle gehörigen Bitsequenz der Kennung emittiert.According to at least one embodiment of the method, this includes the step of simultaneously driving the light sources, so that each of the light sources is a luminous sequence emitted according to the corresponding to the respective light source bit sequence of the identifier.

Zeitgleich bedeutet insbesondere, dass alle Lichtquellen innerhalb eines Takts einer Taktfrequenz angesteuert werden und eine einem Steuersignal entsprechende Lichtintensität oder Leuchtzustand in dem Takt emittieren können. Zeitgleich bedeutet zum Beispiel innerhalb einer Zeitspanne von einer Sekunde, bevorzugt innerhalb von 500 ms oder innerhalb von 250 ms. Mindestens am Ende eines Taktes emittieren alle Lichtquellen eine für diesen Takt durch das Steuersignal vorgegebene Helligkeit, also den vorgegebenen, einem Bit aus der Bitsequenz entsprechenden Leuchtzustand. Es ist die Dauer eines Taktes insbesondere größer als die Zeitspanne, die nötig ist, bis alle Lichtquellen gemäß dem Steuersignal emittieren. Die Leuchtsequenzen aller Lichtquellen laufen bevorzugt parallel und korreliert, also synchron, zeitgleich und im selben Takt, ab. Es emittieren alle Lichtquellen zeitgleich eine Helligkeit zum Beispiel entsprechend einem zehnten Bit der Bitsequenz.At the same time, this means, in particular, that all the light sources within a clock of a clock frequency are driven and can emit a control signal corresponding light intensity or lighting state in the clock. At the same time means, for example, within a period of one second, preferably within 500 ms or within 250 ms. At least at the end of a clock, all the light sources emit a brightness predetermined for that clock by the control signal, that is to say the predetermined luminous state corresponding to one bit from the bit sequence. In particular, the duration of a clock is greater than the time required until all the light sources emit in accordance with the control signal. The light sequences of all light sources preferably run in parallel and correlated, ie synchronously, simultaneously and in the same cycle. All light sources simultaneously emit a brightness, for example, corresponding to one tenth bit of the bit sequence.

Dass jede der zu lokalisierenden Lichtquellen eine Leuchtsequenz entsprechend der zu der Lichtquelle gehörigen Bitsequenz der Kennung emittiert, bedeutet, dass die von den einzelnen Lichtquellen emittierten Leuchtzustände im Zeitverlauf der Bitfolge der Bitsequenz der jeweiligen Lichtquelle entsprechen. Die jeweilige Lichtquelle wird also beispielsweise bei einer 1 in der Bitsequenz eingeschaltet und bei einer 0 in der Bitsequenz ausgeschaltet. Die Einschaltvorgänge sowie die Ausschaltvorgänge sind somit durch die einzelnen aufeinander folgenden Bits der Bitsequenz vorgegebenen. Lautet ein Teil der Bitsequenz zum Beispiel 1001, so wird im ersten Takt die zugehörige Lichtquelle eingeschaltet, im zweiten Takt ausgeschaltet, bleibt im dritten Takt ausgeschaltet und wird im vierten Takt wieder eingeschaltet.The fact that each of the light sources to be located emits a luminous sequence corresponding to the bit sequence of the identifier belonging to the light source means that the luminous states emitted by the individual light sources correspond to the bit sequence of the respective light source over the course of time. The respective light source is thus switched on, for example, at a 1 in the bit sequence and turned off at a 0 in the bit sequence. The switch-on and the switch-off are thus predetermined by the individual consecutive bits of the bit sequence. For example, if part of the bit sequence is 1001, then the first clock will be the corresponding light source switched on, off in the second cycle, remains off in the third cycle and is turned on again in the fourth cycle.

Gemäß zumindest einer Ausführungsform des Verfahrens umfasst dieses den Schritt des Aufnehmens einer Bildersequenz der Anordnung mit einem Bildaufnahmegerät. Bei dem Bildaufnahmegerät handelt es sich bevorzugt um ein digitales Bildaufnahmegerät wie eine Digitalkamera, beispielsweise um eine so genannte Webcam.In accordance with at least one embodiment of the method, this comprises the step of recording an image sequence of the arrangement with an image capture device. The image recording device is preferably a digital image recording device such as a digital camera, for example a so-called webcam.

Gemäß zumindest einer Ausführungsform des Verfahrens ist die Bildersequenz mit der Leuchtsequenz korreliert. Die Bildersequenz weist insbesondere eine Abfolge einzelner Bilder auf und die Abfolge der Bilder ist gezielt auf die Leuchtsequenzen abgestimmt. Beispielsweise wird pro Takt, insbesondere gegen Ende des Taktes, genau ein Bild aufgezeichnet. Jeder der Leuchtzustände der parallel ablaufenden Leuchtsequenzen wird bevorzugt durch eines der Bilder erfasst. Die Bildersequenz stellt mit anderen Worten eine Aufzeichnung der Leuchtsequenzen durch das Bildaufnahmegerät, insbesondere zu bestimmten Zeitpunkten, dar.In accordance with at least one embodiment of the method, the image sequence is correlated with the luminous sequence. In particular, the sequence of images has a sequence of individual images, and the sequence of images is specifically matched to the luminous sequences. For example, per clock, especially towards the end of the clock, exactly one picture is recorded. Each of the luminous states of the parallel-running luminous sequences is preferably detected by one of the images. In other words, the image sequence represents a recording of the luminous sequences by the image recording device, in particular at specific points in time.

In mindestens einer Ausführungsform des Verfahrens ist dieses zur Lokalisierung von Lichtquellen eingerichtet und weist mindestens die folgenden Schritte auf:

  • Erstellen einer Liste von Lichtquellen einer Anordnung mit einer Mehrzahl von Lichtquellen, wobei jede der Lichtquellen eine eindeutige digitale Kennung mit einer Bitsequenz aufweist,
  • zeitgleiches Ansteuern der Lichtquellen, sodass jede der Lichtquellen eine Leuchtsequenz entsprechend der zu der jeweiligen Lichtquelle gehörigen Bitsequenz der Kennung emittiert, und
  • Aufnehmen einer Bildsequenz der Anordnung mit einem Bildaufnahmegerät während des Ansteuerns, wobei eine Abfolge von Bildern der Bildersequenz auf eine Abfolge von Leuchtzuständen der Leuchtsequenz gezielt abgestimmt ist.
In at least one embodiment of the method, this is set up for the localization of light sources and has at least the following steps:
  • Creating a list of light sources of an array having a plurality of light sources, each of the light sources having a unique digital identifier having a bit sequence,
  • Simultaneously driving the light sources, so that each of the light sources, a luminous sequence corresponding to that of the respective light source belonging to the bit sequence of the identifier, and
  • Picking up an image sequence of the arrangement with an image recording device during the activation, wherein a sequence of images of the image sequence is specifically matched to a sequence of luminous states of the luminous sequence.

Dadurch, dass jede der Lichtquellen im Zeitverlauf eine Leuchtsequenz mit Leuchtzuständen entsprechend der Bitsequenz der Kennung emittiert, sind die Lichtquellen in der Bildersequenz einer Kennung zuordenbar und eindeutig lokalisierbar.Because each of the light sources emits a luminous sequence with luminous states in accordance with the bit sequence of the identifier over time, the light sources in the image sequence can be assigned to an identifier and can be uniquely localized.

Gemäß zumindest einer Ausführungsform des Verfahrens umfasst dieses den Schritt des Festlegens eines oder mehrerer Ausgangspunkte, wobei jeder Ausgangspunkt durch eine oder durch mehrere bestimmte Lichtquellen gebildet ist. Wird ein zweidimensionales Modell der Anordnung erstellt, so können bei Vorhandensein eines Ausgangspunktes die Positionen der Lichtquellen auf diesen Ausgangspunkt bezogen werden. Bevorzugt ist eine räumliche Position des Ausgangspunktes in der Anordnung bekannt. Es ist möglich, dass die Lichtquelle, die den Ausgangspunkt darstellt, zuerst lokalisiert wird und anschließend eine Referenzierung der weiteren Lichtquellen darauf erfolgt. Ebenso kann der Ausgangspunkt vor dem Ansteuern der Lichtquellen mit der Bitsequenz bestimmt werden, zum Beispiel durch ein dezidiertes Aufleuchten, und etwa ein Bildmittelpunkt der Bilder und/oder das Bildaufnahmegerät darauf ausgerichtet werden. Weiterhin ist es möglich, dass mindestens drei Ausgangspunkte ermittelt werden, deren räumliche Lage zueinander bekannt ist. Hierdurch ist eine Abstandsbestimmung des Bildaufnahmegeräts zu den Ausgangspunkten und einen Angabe eine Metrik möglich. Gemäß zumindest einer Ausführungsform des Verfahrens umfasst dieses einen Schritt, bei dem alle Lichtquellen mindestens einmal gemeinsam angeschaltet und mindestens einmal gemeinsam ausgeschaltet werden. Bevorzugt werden die Lichtquellen mehrmals hintereinander gemeinsam eingeschaltet und wieder ausgeschaltet. Durch das gemeinsame Anschalten und Ausschalten der Lichtquellen können in den Bildern der Bildersequenz Lichtquellenbereiche bestimmt werden. Die Lichtquellenbereiche sind dann solche Bereiche, eingeschränkt bevorzugt auf bestimmte Bildpunkte oder Pixel in den Bildern, in denen eine Helligkeit entsprechend des Anschaltens und Ausschaltens moduliert ist. Bevorzugt ist in den Lichtquellenbereichen jeweils mindestens eine der Lichtquellen oder genau eine der Lichtquellen der Anordnung abgebildet. In jedem der Lichtquellenbereiche ist im Verlauf der Bilder der Bildersequenz also bevorzugt eine Leuchtsequenz einer der Lichtquellen aufgezeichnet.In accordance with at least one embodiment of the method, the method comprises the step of determining one or more starting points, each starting point being formed by one or more specific light sources. If a two-dimensional model of the arrangement is created, the positions of the light sources can be referenced to this starting point in the presence of a starting point. Preferably, a spatial position of the starting point in the arrangement is known. It is possible that the light source, which represents the starting point, is first localized and then a referencing of the further light sources takes place thereon. Likewise, the starting point may be determined prior to driving the light sources with the bit sequence, for example by a dedicated light up, and aligning about an image center of the images and / or the image capture device thereon. Furthermore, it is possible that at least three starting points are determined whose spatial position is known to each other. This makes it possible to determine the distance of the image recording device to the starting points and to specify a metric. According to at least one embodiment of the method, this comprises a step in which all the light sources are switched on together at least once and switched off at least once together. The light sources are preferably switched on several times in succession and switched off again. By jointly switching on and off the light sources can be determined in the images of the image sequence light source areas. The light source areas are then those areas, preferably limited to certain pixels or pixels in the images, in which a brightness is modulated in accordance with the turn-on and turn-off. In each case at least one of the light sources or exactly one of the light sources of the arrangement is preferably imaged in the light source regions. In each of the light source areas, a light sequence of one of the light sources is therefore preferably recorded in the course of the images of the image sequence.

Gemäß zumindest einer Ausführungsform des Verfahrens wird von allen Bildern der Bildersequenz ein Ausgangsbild der Anordnung subtrahiert. Bei dem Ausgangsbild sind bevorzugt alle Lichtquellen ausgeschaltet. Durch das Abziehen des Ausgangsbildes von den Bildern der Bildersequenz ist ein Hintergrund der Anordnung reduzierbar oder eliminierbar, wodurch die Lichtquellenbereiche genauer bestimmbar sind. Bei dem Ausgangsbild kann es sich auch um mehrere Einzelbilder bei ausgeschalteten Lichtquellen handeln, über die gemittelt wird, zum Beispiel um eine schwankende Hintergrundhelligkeit in den Bildern der Bildersequenz effizient abzuziehen.In accordance with at least one embodiment of the method, an output image of the arrangement is subtracted from all images of the image sequence. In the output image, all light sources are preferably switched off. By subtracting the output image from the images of the image sequence, a background of the arrangement can be reduced or eliminated, whereby the light source regions can be determined more accurately. The output image can also be a plurality of individual images with light sources switched off, which are averaged over, for example, to efficiently subtract a fluctuating background brightness in the images of the image sequence.

Gemäß zumindest einer Ausführungsform des Verfahrens wird ein Verlauf einer Helligkeit der Lichtquellenbereiche, also eine der Leuchtsequenzen, mit der Bitsequenz der Kennung verglichen. Erscheint einer der Lichtquellenbereiche in aufeinander folgenden Bildern der Bildersequenz beispielsweise erst hell, dann dunkel, wieder dunkel und dann wieder hell, so wird diesem Verlauf der Helligkeit eine Bitabfolge von 1001 zugeordnet. Diese Bitabfolge wird mit der Bitsequenz der Kennung verglichen. Stimmt die Bitsequenz mit der Bitabfolge aus dem Verlauf der Helligkeit überein, lässt sich die entsprechende Lichtquelle mit der zugehörigen eindeutigen Kennung oder der eindeutigen Bitsequenz dem entsprechenden Lichtquellenbereich eindeutig zuordnen. Die Bitabfolge umfasst insbesondere mindestens 16 Bit, bevorzugt mindestens 32 Bit oder mindestens 48 Bit.In accordance with at least one embodiment of the method, a profile of a brightness of the light source regions, that is a the luminous sequences, compared with the bit sequence of the identifier. If, for example, one of the light source areas in consecutive pictures of the picture sequence first appears bright, then dark, again dark and then bright again, a bit sequence of 1001 is assigned to this curve of the brightness. This bit sequence is compared with the bit sequence of the identifier. If the bit sequence corresponds to the bit sequence from the course of the brightness, the corresponding light source with the associated unique identifier or the unique bit sequence can be unambiguously assigned to the corresponding light source region. In particular, the bit sequence comprises at least 16 bits, preferably at least 32 bits or at least 48 bits.

Gemäß zumindest einer Ausführungsform des Verfahrens umfasst mindestens einer der Lichtquellenbereiche mehrere Bildpunkte der Bilder. Aus den mehreren Bildpunkten wird bevorzugt einer der Bildpunkte zum Vergleich der Leuchtsequenz mit der Bitsequenz ausgesucht. Beispielsweise handelt es sich bei dem ausgesuchten Bildpunkt um den Bildpunkt maximaler Helligkeit oder um einen zentral in den mehreren Bildpunkt gelegenen Bildpunkt. Alternativ oder zusätzlich ist es möglich, dass über die mehreren Bildpunkte des Lichtquellenbereichs gemittelt wird und dieser gemittelte Wert zum Vergleich des Verlaufs der Helligkeit mit der Bitsequenz herangezogen wird.In accordance with at least one embodiment of the method, at least one of the light source regions comprises a plurality of pixels of the images. From the plurality of pixels, one of the pixels is preferably selected for comparison of the luminous sequence with the bit sequence. By way of example, the selected pixel is the pixel of maximum brightness or a pixel located centrally in the plurality of pixels. Alternatively or additionally, it is possible to average over the plurality of pixels of the light source region and to use this averaged value to compare the progression of the brightness with the bit sequence.

Gemäß zumindest einer Ausführungsform des Verfahrens ist jedes Bild der Bildersequenz genau einem Leuchtzustand der Leuchtsequenzen zugeordnet. Bevorzugt ist eine Anzahl der Bilder der Bildersequenz gleich einer Anzahl der Leuchtzustände der Leuchtsequenzen und gleich einer Anzahl von Bits der Bitsequenz. Umfasst die Bitsequenz beispielsweise 32 Bit, so umfasst auch die Bildersequenz 32 Bilder und jede der Leuchtsequenzen umfasst 32 Leuchtzustände.In accordance with at least one embodiment of the method, each image of the image sequence is assigned exactly to a lighting state of the lighting sequences. Preferably, a number of the images of the image sequence is equal to a number of the luminous states of the luminous sequences and equal to a number of bits of the bit sequence. For example, if the bit sequence comprises 32 bits, the image sequence also includes 32 bits Images and each of the light sequences includes 32 light states.

Gemäß zumindest einer Ausführungsform des Verfahrens beinhaltet die Bitsequenz die vollständige, eindeutige Kennung. Mit anderen Worten können die Bitsequenz und die Kennung identisch sein. Weiterhin ist es möglich, dass vor oder nach der Bitsequenz weitere Bitabfolgen vorausgehen und/oder nachfolgen. Beispielsweise geht der Bitsequenz eine Einleitungssequenz voraus und/oder eine Prüfsummensequenz nach.In accordance with at least one embodiment of the method, the bit sequence includes the complete, unique identifier. In other words, the bit sequence and the identifier may be identical. Furthermore, it is possible for further bit sequences to precede and / or follow before or after the bit sequence. For example, the bit sequence precedes an initiation sequence and / or a checksum sequence.

Gemäß zumindest einer Ausführungsform des Verfahrens werden mindestens zwei Bildaufnahmegeräte eingesetzt. Hierdurch ist eine dreidimensionale Erfassung der Lichtquellen möglich.In accordance with at least one embodiment of the method, at least two image recording devices are used. As a result, a three-dimensional detection of the light sources is possible.

Gemäß zumindest einer Ausführungsform des Verfahrens wird die Anordnung der Lichtquellen dreidimensional erfasst, wobei nur ein einziges Bildaufnahmegerät eingesetzt wird, das verschoben wird und anschließend dann nochmals die Lichtquellen gemäß der Bitsequenz angesteuert werden. Das heißt, das Bildaufnahmegerät wird zuerst in eine erste Position und dann in eine zweite Position gebracht, wobei eine räumliche Lage der Positionen zueinander bekannt ist. Hierdurch ist ebenfalls eine stereoskopische Aufnahme der Anordnung ermöglicht.In accordance with at least one embodiment of the method, the arrangement of the light sources is detected three-dimensionally, wherein only a single image recording device is used, which is displaced and then the light sources are then driven again according to the bit sequence. That is, the image pickup device is first brought to a first position and then to a second position, wherein a spatial position of the positions to each other is known. As a result, a stereoscopic image of the arrangement is also possible.

Gemäß zumindest einer Ausführungsform des Verfahrens werden die Lichtquellen mehrmals nacheinander mit der Bitsequenz angesteuert und von dem mindestens einen Bildaufnahmegerät wird jeweils nur ein Teil der Anordnung erfasst. Mit anderen Worten ist jeweils eine Bildersequenz nur auf einen Teil der Anordnung gerichtet. Verbleibende Teile der Anordnung können durch weitere Bildersequenzen erfasst werden. Durch ein Aneinanderlegen von mehreren Bildaufnahmebereichen der einzelnen Bildersequenzen sind dann alle Lichtquellen der Anordnung lokalisierbar.In accordance with at least one embodiment of the method, the light sources are activated several times in succession with the bit sequence, and in each case only a part of the arrangement is detected by the at least one image recording device. In other words, an image sequence is directed only to a part of the arrangement. Remaining parts of the arrangement can be detected by further picture sequences. By juxtaposing several image recording areas of the individual image sequences, all the light sources of the arrangement can then be localized.

Gemäß zumindest einer Ausführungsform des Verfahrens ist die Anordnung der Lichtquellen zur Ausleuchtung oder zur Beleuchtung eines Gebäudeteils vorgesehen. Alternativ oder zusätzlich ist die Anordnung der Lichtquellen an einem Gebäudeteil angebracht oder zur Anbringung an einem Gebäudeteil eingerichtet. Die Anordnung kann also Teil eines Beleuchtungssystems zur Architekturbeleuchtung sein.In accordance with at least one embodiment of the method, the arrangement of the light sources is provided for illuminating or for illuminating a building part. Alternatively or additionally, the arrangement of the light sources is attached to a building part or set up for attachment to a building part. The arrangement can thus be part of a lighting system for architectural lighting.

Darüber hinaus wird ein Computerprogramm angegeben. Das Computerprogramm weist einen Programmcode auf, durch das ein Verfahren gemäß mindestens einer der vorhergehenden Ausführungsformen ausgeführt wird, wenn das Computerprogramm in einem Computer abgearbeitet wird. Merkmale des Verfahrens sind daher auch für das Computerprogramm offenbart und umgekehrt.In addition, a computer program is specified. The computer program has a program code, by means of which a method according to at least one of the preceding embodiments is executed when the computer program is executed in a computer. Features of the method are therefore also disclosed for the computer program and vice versa.

Schließlich wird eine Lokalisierungseinheit zur Lokalisierung von Lichtquellen eines Beleuchtungssystems angegeben. Das Lokalisierungssystem umfasst mindestens einen Rechner sowie eine Datenverbindung, die dazu eingerichtet ist, mit der Anordnung der Mehrzahl von Lichtquellen des Beleuchtungssystems verbunden zu werden. Die Lichtquellen oder Gruppen von Lichtquellen sind hierbei einzeln ansteuerbar. Weiterhin beinhaltet die Lokalisierungseinheit mindestens ein digitales Bildaufnahmegerät. Die Lokalisierungseinheit ist ferner dazu eingerichtet, ein Verfahren gemäß einer der vorhergehenden Ausführungsformen und/oder ein entsprechendes Computerprogramm auszuführen. Merkmale des Verfahrens sowie des Computerprogramms sind daher auch für die Lokalisierungseinheit offenbart und umgekehrt.Finally, a localization unit for locating light sources of a lighting system is provided. The location system includes at least one computer and a data link configured to be connected to the array of the plurality of light sources of the lighting system. The light sources or groups of light sources can be controlled individually. Furthermore, the localization unit includes at least one digital image capture device. The localization unit is further configured to execute a method according to one of the preceding embodiments and / or a corresponding computer program. Features of the method and of the computer program are therefore also disclosed for the localization unit and vice versa.

Nachfolgend wird ein hier beschriebenes Verfahren sowie eine hier beschriebene Lokalisierungseinheit unter Bezugnahme auf die Zeichnung anhand von Ausführungsbeispielen näher erläutert. Gleiche Bezugszeichen geben dabei gleiche Elemente in den einzelnen Figuren an.

FIG. 2
a schematic representation of a method described here for the localization of light sources.

In Figur 1 ist schematisch ein Beleuchtungssystem 5 mit einer Anordnung 10 mit einer Mehrzahl von Lichtquellen 1 illustriert. Solche Beleuchtungssysteme 5 sind in der Druckschrift WO 2010/088887 A2 sowie in der Druckschrift DE 10 2009 007 505 A1 angegeben, deren Offenbarungsgehalt durch Rückbezug mit aufgenommen wird.In FIG. 1 schematically illustrates an illumination system 5 with an arrangement 10 with a plurality of light sources 1 illustrated. Such lighting systems 5 are in the document WO 2010/088887 A2 as well as in the publication DE 10 2009 007 505 A1 whose disclosure is included by reference.

Bei den Lichtquellen 1 des Beleuchtungssystems 5 handelt es sich beispielsweise um Halbleiterlichtquellen wie Leuchtdioden. Mehrere der Lichtquellen 1 sind über eine Datenleitung 7a an eine Ansteuervorrichtung 8 angeschlossen. Bei der Datenleitung 7a handelt es sich insbesondere um einen Control Bus, der über ein RDM-Protokoll oder ein RDM-ähnliches Protokoll betreibbar ist. Das Beleuchtungssystem 5 umfasst mehrere Ansteuervorrichtungen 8. Die Anzahl der Ansteuervorrichtungen 8 sowie der Lichtquellen 1 ist in Figur 1 nur grob vereinfacht dargestellt.The light sources 1 of the illumination system 5 are, for example, semiconductor light sources such as LEDs. Several of the light sources 1 are connected to a drive device 8 via a data line 7a. The data line 7a is in particular a control bus which can be operated via an RDM protocol or an RDM-like protocol. The illumination system 5 comprises a plurality of drive devices 8. The number of drive devices 8 and the light sources 1 is shown in FIG FIG. 1 only roughly illustrated.

Die Ansteuervorrichtungen 8 sind über eine weitere Datenleitung 7b, beispielsweise über eine Internetverbindung oder über eine drahtlose Funkverbindung, mit einer Steuereinheit 9 verbunden. Bei der Steuereinheit 9 handelt es sich beispielsweise um einen Computer. Die Steuereinheit 9 gibt Steuersignale an die Ansteuervorrichtungen 8 aus, die durch die Ansteuervorrichtungen 8 aufbereitet und an die Lichtquellen 1 weitergeleitet werden können. Beispielsweise sind durch das Beleuchtungssystem 5 zeitlich veränderliche Beleuchtungsmuster darstellbar.The control devices 8 are connected via a further data line 7b, for example via an Internet connection or via a wireless radio link, to a control unit 9. The control unit 9 is, for example, a computer. The control unit 9 outputs control signals to the drive devices 8, which can be processed by the drive devices 8 and forwarded to the light sources 1. For example, time-variable illumination patterns can be displayed by the illumination system 5.

Über eine Datenverbindung 3, in Figur 1 durch eine Strich-Linie symbolisiert, ist eine Lokalisierungseinheit 4 mit dem Beleuchtungssystem 5 verbunden. Bei der Datenverbindung 3 handelt es sich um eine Drahtverbindung oder um eine drahtlose Funkverbindung.Via a data connection 3, in FIG. 1 symbolized by a dash line, a localization unit 4 is connected to the lighting system 5. The data connection 3 is a wired connection or a wireless radio connection.

Die Lokalisierungseinheit 4 umfasst einen Rechner 2, auf dem ein Programm mit einem Verfahren zur Lokalisierung der Lichtquellen 1 implementiert ist. Ferner ist mit dem Rechner 2 ein Bildaufnahmegerät 6 verbunden. Bei dem Bildaufnahmegerät 6 handelt es sich bevorzugt um eine so genannte Webcam. Mittels des Bildaufnahmegeräts 6 ist mindestens ein Teil der Anordnung 10 oder die gesamte Anordnung 10 der Lichtquellen 1 abbildbar. Ein Abstand der Anordnung 10 zu dem Bildaufnahmegerät 6 ist bevorzugt so gewählt, dass einzelne Lichtquellen 1 von dem Bildaufnahmegerät 6 auflösbar sind. Anders als in Figur 1 dargestellt ist es ebenso möglich, dass die Lokalisierungseinheit 4 zwei oder mehr Bildaufnahmegeräte 6 aufweist.The localization unit 4 comprises a computer 2, on which a program with a method for localizing the light sources 1 is implemented. Furthermore, an image recording device 6 is connected to the computer 2. The image recording device 6 is preferably a so-called webcam. By means of the image pickup device 6 is at least a part of the assembly 10 or the entire Arrangement 10 of the light sources 1 can be imaged. A distance of the arrangement 10 to the image recording device 6 is preferably selected such that individual light sources 1 can be resolved by the image recording device 6. Unlike in FIG. 1 it is also possible that the localization unit 4 has two or more image recording devices 6.

In Figur 2 ist ein Ausführungsbeispiel eines Verfahrens zur Lokalisierung der Lichtquellen 1 schematisch illustriert. Stark vereinfacht weist die Anordnung 10 gemäß Figur 2A lediglich drei Lichtquellen 1a, 1b, 1c auf.In FIG. 2 an embodiment of a method for the localization of the light sources 1 is schematically illustrated. Very simplified, the arrangement 10 according to FIG. 2A only three light sources 1a, 1b, 1c.

In einem Schritt des Verfahrens, vergleiche Figur 2B, wird eine Liste L erstellt, in der alle Lichtquellen 1a, 1b, 1c sowie deren Kennungen 14a, 14b, 14c aufgeführt sind. Die Kennungen 14a, 14b, 14c erlauben eine eindeutige, logische Identifizierung und Adressierung der Lichtquellen 1a, 1b, 1c der Anordnung 10. Gemäß Figur 2B weisen die Kennungen 14a, 14b, 14c schematisch jeweils nur 4 Bit auf. Bevorzugt umfassen die Kennungen 14a, 14b, 14c jedoch mindestens 32 Bit oder mindestens 48 Bit, sodass auch bei einer sehr großen Anzahl von Lichtquellen 1 der Anordnung 10 eindeutige Kennungen 14a, 14b, 14c vorliegen. Ein Erstellen der Liste L erfolgt beispielsweise mit Hilfe eines RDM-Protokolls oder eines RDM-ähnlichen Protokolls. In diesem Schritt des Verfahrens werden also alle Lichtquellen 1a, 1b, 1c der Anordnung sowie deren Kennungen 14a, 14b, 14c erfasst.In one step of the procedure, compare FIG. 2B , a list L is prepared in which all light sources 1a, 1b, 1c and their identifiers 14a, 14b, 14c are listed. The identifiers 14a, 14b, 14c allow unambiguous, logical identification and addressing of the light sources 1a, 1b, 1c of the arrangement 10. According to FIG FIG. 2B the identifiers 14a, 14b, 14c schematically each only 4 bits. However, the identifiers 14a, 14b, 14c preferably comprise at least 32 bits or at least 48 bits, so that even with a very large number of light sources 1 of the arrangement 10, there are unique identifiers 14a, 14b, 14c. The list L is created, for example, using an RDM protocol or an RDM-like protocol. In this step of the method, therefore, all light sources 1a, 1b, 1c of the arrangement as well as their identifiers 14a, 14b, 14c are detected.

In Figur 2C ist ein Bild P der Anordnung 10 dargestellt. Das Bild P ist mit dem Bildaufnahmegerät 6 der Lokalisierungseinheit 4 aufgenommen, vergleiche Figur 1. In Figur 2D ist eine Ansteuerung der Lichtquellen 1a, 1b, 1c in Abhängigkeit von der Zeit t illustriert. Gegenüber der Zeit t ist jeweils ein Verlauf einer Helligkeit I der Lichtquellen 1a, 1b, 1c, also Leuchtsequenzen 11a, 11b, 11c der einzelnen Lichtquellen 1a, 1b, 1c, aufgetragen.In Figure 2C an image P of the arrangement 10 is shown. The image P is taken with the image pickup device 6 of the localization unit 4, cf. FIG. 1 , In FIG. 2D is a control of the light sources 1a, 1b, 1c in Dependence on time t illustrated. Compared with the time t, in each case a profile of a brightness I of the light sources 1a, 1b, 1c, that is to say luminous sequences 11a, 11b, 11c of the individual light sources 1a, 1b, 1c, is plotted.

Die Lichtquellen 1a, 1b, 1c werden zeitgleich und synchron mit einer bestimmten Taktrate angesteuert, siehe Figur 2D. Für jeden Takt wird ein Bild P1-P10 aufgezeichnet. Zur Reduzierung von Hintergrundhelligkeit wird vor der weiteren Verarbeitung der Bilder P1-P10 bevorzugt von allen Bildern P1-P10 ein Ausgangsbild subtrahiert, wobei bei dem Ausgangsbild alle Lichtquellen 1a, 1b, 1c ausgeschaltet sind. Bei dem Ausgangsbild handelt es sich beispielsweise um das Bild P6 oder um ein vor der Einleitungssequenz 13 aufgenommenes Bild.The light sources 1a, 1b, 1c are driven simultaneously and synchronously with a specific clock rate, see FIG. 2D , For each bar an image P1-P10 is recorded. To reduce the background brightness, an output image is preferably subtracted from all the images P1-P10 prior to the further processing of the images P1-P10, with all the light sources 1a, 1b, 1c being switched off in the output image. The output image is, for example, the image P6 or an image taken before the introduction sequence 13.

Bevorzugt wird an alle Lichtquellen 1a, 1b, 1c gemeinsam zuerst ein Steuersignal mit einer Einleitungssequenz 13 mit beispielsweise sechs aufeinander folgenden Bits der Abfolge 101010 angelegt. Hieraus resultieren sechs zeitlich aufeinander folgende Leuchtzustände M in der dreimaligen Abfolge hell-dunkel. Es werden die Lichtquellen 1a, 1b, 1c also drei Mal nacheinander gemeinsam eingeschaltet und anschließend gemeinsam ausgeschaltet.Preferably, a control signal having an introduction sequence 13 with, for example, six consecutive bits of the sequence 101010 is applied jointly to all light sources 1a, 1b, 1c. This results in six temporally successive luminous states M in the three-time sequence light-dark. The light sources 1a, 1b, 1c are therefore switched on together three times in succession and then switched off together.

Durch das mehrmalige Einschalten und Ausschalten der Lichtquellen 1a, 1b, 1c während der Einleitungssequenz 13 sind in dem Bild P, vergleiche Figur 2C, Lichtquellenbereiche 12a, 12b, 12c identifizierbar. Die Lichtquellenbereiche 12a, 12b, 12c sind solche Bereiche in dem Bild P, in denen die Lichtquellen 1a, 1b, 1c abgebildet sind. Aus den Lichtquellenbereichen 12a, 12b, 12c wird zum Beispiel ein einzelner Bildpunkt, englisch Pixel, herangezogen, um die Leuchtsequenzen 11a, 11b, 11c darzustellen, vergleiche Figur 2D.By repeatedly turning on and off the light sources 1a, 1b, 1c during the introduction sequence 13, in the image P, compare Figure 2C , Light source regions 12a, 12b, 12c identifiable. The light source regions 12a, 12b, 12c are those regions in the image P in which the light sources 1a, 1b, 1c are imaged. From the light source areas 12a, 12b, 12c, for example, a single pixel, English pixel, is used to surround the Illuminated sequences 11a, 11b, 11c represent, compare FIG. 2D ,

Nach der Einleitungssequenz 13, die an alle Lichtquellen 1a, 1b, 1c gemeinsam angelegt wird, werden die Lichtquellen 1a, 1b, 1c synchron gemäß ihrer individuellen Kennungen 14a, 14b, 14c oder mit zumindest einer Bitsequenz aus den Kennungen 14a, 14b, 14c angesteuert. Zum Beispiel in dem Lichtquellenbereich 12a in den Bildern P7-P10 wird die Leuchtsequenz 11a mit der Bitsequenz 0101 aus der Kennung 14a aufgezeichnet. Jedes der Bilder P7-P10 ist genau einem Leuchtzustand M in den Leuchtsequenzen 11a, 11b, 11c zugeordnet. Die zeitliche Abfolge der Leuchtzustände M ist mit den Bildern P1-P10 der Bildersequenz eins zu eins korreliert.After the initiation sequence 13, which is applied jointly to all the light sources 1a, 1b, 1c, the light sources 1a, 1b, 1c are driven synchronously according to their individual identifiers 14a, 14b, 14c or with at least one bit sequence from the identifiers 14a, 14b, 14c , For example, in the light source area 12a in the images P7-P10, the luminous sequence 11a is recorded with the bit sequence 0101 from the flag 14a. Each of the images P7-P10 is associated with exactly one luminous state M in the luminous sequences 11a, 11b, 11c. The temporal sequence of the luminous states M is correlated with the images P1-P10 of the image sequence one to one.

Dadurch, dass die Kennungen 14a, 14b, 14c im zeitlichen Verlauf der Helligkeiten I und somit in den einzelnen Leuchtsequenzen 11a, 11b, 11c in den Lichtquellenbereichen 12a, 12b, 12c auftreten, lässt sich der Lichtquellenbereich 12a der Lichtquelle 1a, der Lichtquellenbereich 12b der Lichtquellen 1c und der Lichtquellenbereich 12c der Lichtquelle 1b eindeutig zuordnen, in Figur 2D durch einen Doppelpfeil symbolisiert.Due to the fact that the identifiers 14a, 14b, 14c occur in the time course of the brightnesses I and thus in the individual luminous sequences 11a, 11b, 11c in the light source regions 12a, 12b, 12c, the light source region 12a of the light source 1a, the light source region 12b of FIG Light sources 1c and the light source region 12c of the light source 1b uniquely assign, in FIG. 2D symbolized by a double arrow.

Optional kann den Kennungen 14a, 14b, 14c eine weitere Abfolge von Bits, beispielsweise eine Prüfsummensequenz 15, nachfolgen.Optionally, the identifiers 14a, 14b, 14c may be followed by a further sequence of bits, for example a checksum sequence 15.

Eine Dauer der Takte beträgt beispielsweise zirka 200 ms. Mit anderen Worten beträgt dann ein Zeitabstand zwischen zwei aufeinander folgenden Bildern P ebenfalls zirka 200 ms. In Figur 2 ist stark vereinfachend eine Abfolge von nur 10 Bits an die Lichtquellen 1a, 1b, 1c angelegt. Eine praktikable Abfolge von Bits, die an die Lichtquellen angelegt wird, umfasst beispielsweise eine Einleitungssequenz von 16 Bit, eine eindeutige Kennung von 48 Bit und eine Prüfsummensequenz von 16 Bit, entsprechend einer Sequenz von insgesamt 80 Bit. Durch die beispielsweise 48 Bit aufweisende Kennung ist eine sehr große Anzahl von Lichtquellen eindeutig adressierbar. Durch die Aufnahme der Anzahl der Bilder, die der Anzahl der Bits der Abfolge entspricht, ist innerhalb von kurzer Zeit auch eine Lokalisierung und Zuordnung der Lichtquellen bei einer großen Anzahl von Lichtquellen möglich, insbesondere unabhängig von der exakten Anzahl der Lichtquellen. Innerhalb von beispielsweise weniger als 30 Sekunden können so auch hunderte oder tausende von Lichtquellen des Beleuchtungssystems lokalisiert werden.A duration of the clocks is for example about 200 ms. In other words, then a time interval between two consecutive images P is also about 200 ms. In FIG. 2 is simplistic a sequence of only 10 bits applied to the light sources 1a, 1b, 1c. A practical sequence of bits applied to the light sources includes, for example, a 16-bit initiation sequence, a 48-bit unique identifier, and a 16-bit checksum sequence, corresponding to a total of 80-bit sequence. By having, for example, 48-bit identifier is a very large number of light sources uniquely addressable. By recording the number of images, which corresponds to the number of bits of the sequence, a localization and assignment of the light sources in a large number of light sources is possible within a short time, in particular independent of the exact number of light sources. Within less than 30 seconds, for example, hundreds or thousands of light sources of the lighting system can be located.
