Description

Dispositif pour la prise de photographies à partir d'un point élevé au-dessus du sol. Device for taking photographs from a point high above the ground.
L'invention a pour objet un dispositif gui sert à prendre des photographies à partir d'un point élevé au-dessus du sol, sans que le photographe soit lui-même obligé de se déplacer jusqu'à ce point élevé. On sait que l'on fait couramment de la photographie aérienne à partir d'avions ou d'hélicoptères. Le photographe est à bord avec son appareil photographique. De plus, les photographies de ce genre sont prises à partir d'un point déjà relativement élevé étant donné que les avions, et même les hélicoptères, ne peuvent pas descendre à une très basse altitude en tous lieux, notamment dans les rues des villes et des villages, dans les lieux publics, etc.... Or, il est fréquemment utile de pouvoir photographier une maison, un bâtiment, un terrain, un monument, une manifestation en plein air, etc... d'un point de vue plus élevé que la surface du sol, par exemple d'une hauteur de 5 à 50 m, ou quelquefois plus, alors qu'il n'est pas envisageable de se servir à cette fin d'un avion ou d'un hélicoptère. II est souvent utile aussi de pouvoir photographier à partir d'un point élevé un détail d'une façade de bâtiment, d'une statue, d'une toiture, etc..., ce qu'un avion ou un hélicoptère ne permet pas de faire, non seulement pour des raisons pratiques mais aussi pour des raisons économiques quand on tient compte du coût de l'heure d'utilisation de ces engins.The subject of the invention is a device which is used to take photographs from a high point above the ground, without the photographer himself having to move to this high point. We know that aerial photography from planes and helicopters is common. The photographer is on board with his camera. In addition, photographs of this kind are taken from an already relatively high point since planes, and even helicopters, cannot descend to a very low altitude in all places, especially in the streets of cities and villages, in public places, etc ... However, it is often useful to be able to photograph a house, a building, a ground, a monument, an outdoor demonstration, etc ... from a point of view higher than the surface of the ground, for example from a height of 5 to 50 m, or sometimes more, when it is not possible to use a plane or a helicopter for this purpose. It is often also useful to be able to photograph from a high point a detail of a building facade, a statue, a roof, etc., which an airplane or a helicopter does not allow. to do, not only for practical reasons but also for economic reasons when you take into account the cost of the hour of use of these machines.
L'invention a pour but principal d'apporter un dispositif qui rend possible, d'une manière économique et rapide, de prendre des photographies à partir d'un point élevé au-dessus du sol, le photographe restant à niveau du sol , dans des circonstances où l'emploi d'un avion ou d'un hélicoptère n'est pas envisageable.The main object of the invention is to provide a device which makes it possible, in an economical and rapid manner, to take photographs from a high point above the ground, the photographer remaining at ground level, in circumstances where the use of an airplane or a helicopter cannot be envisaged.
Selon l'invention, on fixe à un moyen d'élévation à partir du sol, d'un type quelconque approprié, un organe porteur sur lequel sont montés une caméra de télévi sion ayant un axe de visée et un appareil photographique ayant un axe de prise de vues; l'un de ces deux appareils - caméra ou appareil photographique - est monté réglable en position de façon que l'axe de visée et l'axe de prise de vues se coupent à une distance prédéterminée qui est la distance à laquelle se trouve le sujet à photographier; le dispositif comprend en plus des moyens de liaison entre la caméra et un écran de télévision resté au sol ainsi que des moyens de télécommande à partir du sol de la position et du fonctionnement de l'appareil photographique.According to the invention, a carrier member on which a television camera is mounted is fixed to a means of elevation from the ground, of any suitable type. an axis of view and a camera having an axis of view; one of these two devices - camera or photographic device - is mounted adjustable in position so that the line of sight and the axis of shooting intersect at a predetermined distance which is the distance at which the subject is to photograph; the device further comprises means of connection between the camera and a television screen remaining on the ground as well as remote control means from the ground of the position and operation of the camera.
De préférence, l'organe porteur est réuni au moyen d'élévation au-dessus du sol par l'intermédiaire d'un support substantiellement en C ayant deux branches parallèles, une première branche servant à la réunion de ce support avec le moyen d'élévation, la seconde branche supportant l'organe porteur. Avantageusement, les deux branches du support en C sont horizontales en position d'utilisation et sont espacées suffisamment pour que l'organe porteur puisse être monté tournant autour de la seconde branche de façon à pouvoir occuper une première position dans laquelle il se trouve avec la caméra de télévision et l'appareil photographique entre les branches du support et une seconde position dans laquelle il se trouve en dehors de ces branches. Selon un mode de réalisation préféré de l'invention, la seconde branche du support est constituée au moins partiellement par l'arbre d'un moteur électrique à télécommande à partir du sol; l'organe porteur est constitué de préférence par une plaque qui est fixée à la carcasse de ce moteur et qui porte sur une de ses faces principales l'appareil photographique et la caméra de télévision.Preferably, the carrier member is joined by means of elevation above the ground by means of a support substantially in C having two parallel branches, a first branch serving to join this support with the means of elevation, the second branch supporting the carrier member. Advantageously, the two branches of the support in C are horizontal in the position of use and are spaced sufficiently so that the carrier member can be mounted rotating around the second branch so as to be able to occupy a first position in which it is located with the television camera and the photographic camera between the branches of the support and a second position in which it is outside these branches. According to a preferred embodiment of the invention, the second branch of the support is formed at least partially by the shaft of an electric motor with remote control from the ground; the carrier member preferably consists of a plate which is fixed to the carcass of this motor and which carries on one of its main faces the photographic camera and the television camera.
De préférence, l'appareil photographique est orientable en position et muni d'une aiguille se déplaçant avec lui en regard d'une plage graduée fixée à la plaque, la graduation indiquant la distance à laquelle l'axe de visée et l'axe de prise de vues se coupent.Preferably, the camera is orientable in position and provided with a needle moving with it opposite a graduated range fixed to the plate, the scale indicating the distance at which the line of sight and the line of sight intersect.
Selon un premier aspect de l'invention, pour les hauteurs de 5 à 30 m environ, le moyen d'élévation est un mât télescopique à développement vertical, l'organe porteur est monté au sommet de ce mât.According to a first aspect of the invention, for heights of 5 to 30 m approximately, the lifting means is a telescopic mast with vertical development, the carrier member is mounted at the top of this mast.
Selon un second aspect de l'invention, pour les hauteurs de 10 m à 50 m et au-delà, le moyen d'élévation est un ballon captif, de préférence un ballon à gaz chauds de type montgolfière en dessous duquel l'organe porteur est suspendu.According to a second aspect of the invention, for heights from 10 m to 50 m and beyond, the lifting means is a captive balloon, preferably a hot-air balloon of the hot air balloon type below which the carrier member is suspended.
On donnera maintenant, sans intention limitative et sans exclure aucune variante, une description de deux exemples de réalisation. On se reportera aux dessins annexés dans lesquels :We will now give, without limiting intention and without excluding any variant, a description of two exemplary embodiments. Reference is made to the appended drawings in which:

- la figure 3 est une vue générale schématique montrant les moyens de liaison et de télécommande,FIG. 3 is a general schematic view showing the connection and remote control means,
- la figure 4 est une vue en élévation, sans échelle précise, montrant un mode de réalisation de l'invention selon son second aspect.- Figure 4 is an elevational view, without precise scale, showing an embodiment of the invention according to its second aspect.
Selon le premier aspect de l'invention, un véhicule automobile 1 est équipé d'un mât télescopique 2, à air comprimé, d'un type connu en soi, par exemple tel que les mâts vendus par la Société française Compagnie Electro-Mécanique. Un mât de ce genre peut être développé jusqu'à une hauteur de 5 à 30 mètres. L'emploi de l'air comprimé est plus commode, mais n'est pas une obligation dans le cadre de l'invention. De plus le mât 2 est muni sur un côté d'un bras d'orientation 3 permettant de le faire tourner sur 360°. Au sommet du mât 2 est fixé un support 4 à profil en C qqi a deux branches parallèles 4A, 4B. La première branche 4A est utilisée pour la fixation au mât 2 en position horizontale, grâce à un raccord vertical 5. La seconde branche 4B est constituée, ou elle est prolongée, par l'arbre 6 d'un moteur 7 à la carcasse 8 duquel est fixé un organe porteur 9. On peut utiliser pour ce montage un moteur de la Société allemande Hirschmann, par exemple. Ainsi, on peut régler l'inclinaison de l'ensemble par rapport à l'horizontale.According to the first aspect of the invention, a motor vehicle 1 is equipped with a telescopic mast 2, with compressed air, of a type known per se, for example such as the masts sold by the French company Compagnie Electro-Mécanique. A mast of this kind can be developed up to a height of 5 to 30 meters. The use of compressed air is more convenient, but is not an obligation within the scope of the invention. In addition, the mast 2 is provided on one side with an orientation arm 3 allowing it to rotate 360 °. At the top of the mast 2 is fixed a support 4 with a C profile which has two parallel branches 4A, 4B. The first branch 4A is used for fixing to the mast 2 in a horizontal position, thanks to a vertical connection 5. The second branch 4B is made up, or it is extended, by the shaft 6 of a motor 7 to the carcass 8 of which a support member 9 is attached. An engine from the German company Hirschmann, for example, can be used for this mounting. Thus, one can adjust the inclination of the assembly relative to the horizontal.
L'organe porteur 9 est avantageusement, mais non obligatoirement, une plaque ayant une face principale 9A sur laquelle sont montés côte à côte une caméra de télévision 10 et un appareil photographique 11. La caméra de télévision 10 a une ligne de viséeThe carrier member 9 is advantageously, but not necessarily, a plate having a main face 9A on which are mounted side by side a television camera 10 and a photographic camera 11. The television camera 10 has a line of sight
12 dessinée en trait mixte et l'appareil photographique 11 a une ligne de prise de vues 13 dessinée en trait mixte simple; cet appareil 11 est monté réglable en orientation autour d'un pivot 14 de façon que sa ligne de prise de vues 13 coupe la ligne de visée 12 de la caméra 10 en un point 15. A titre d'indication pratique, ce point 15 peut se trouver à une distance de 10 m de la caméra 10 et le réglage peut permettre de l'éloigner, en 15', jusqu'à une distance de 20 m ou plus; la ligne de prise de vues est représentée en trait mixte double dans ce dernier cas.12 drawn in phantom and the camera 11 has a shooting line 13 drawn in simple phantom; this device 11 is mounted adjustable in orientation around a pivot 14 so that its line of views 13 intersects the line of sight 12 of the camera 10 at a point 15. As a practical indication, this point 15 can be at a distance of 10 m from camera 10 and the adjustment can allow it to be moved away, in 15 ', up to a distance of 20 m or more; the shooting line is represented by a double dashed line in the latter case.
Pour faciliter le réglage, l'appareil photographique est muni d'une aiguille 16 déplaçable devant une plage graduée 17 dont la graduation correspond à l'éloi- gnement des points 15, 15', etc.... On notera que le croisement en un point 15 ou 15' de la ligne de visée 12 et de la ligne de prise de vues 1 pourrait se faire par l'orientation de la caméra de télévision 10.To facilitate adjustment, the camera is provided with a needle 16 which can be moved in front of a graduated range 17, the graduation of which corresponds to the distance from the points 15, 15 ′, etc. It will be noted that the crossing in a point 15 or 15 ′ of the line of sight 12 and of the shooting line 1 could be done by the orientation of the television camera 10.
La face principale 9A supporte aussi une boîte de relais 18 qui servent à la commande à distance des appareils. L'orientation de l'appareil photographique 11 vers un point 15, ou 15', ou autre, peut se faire manuellement avant le développement du mât 2. Elle peut aussi, dans une variante, être commandée à partir du sol, au moyen d'un moteur analogue au moteur 7 accouplé à l'appareil photographique 11.The main face 9A also supports a relay box 18 which are used for the remote control of the devices. The orientation of the camera 11 to a point 15, or 15 ′, or the like, can be done manually before the development of the mast 2. It can also, in a variant, be controlled from the ground, by means of a motor similar to the motor 7 coupled to the camera 11.
La figure 3 montre schématiquement les moyens de liaison et de télécommande entre les organes supportés au sommet du mât et les organes restés au niveau du sol. Ces derniers comprennent un écran de télévision 19 relié à la caméra 10 par un câble coaxial 20 auquel sont adjoints des câbles 21 d'alimentation électrique. Il existe aussi, au niveau du sol, un organe de commande 22 relié par un câble 23 à trois conducteurs au moteur 7 pour faire tourner ce dernier, à vitesse très lente, afin de donner l'inclinaison désirée à l'ensemble supporté par le mât 2.FIG. 3 schematically shows the means of connection and remote control between the members supported at the top of the mast and the members remaining at ground level. The latter include a television screen 19 connected to the camera 10 by a coaxial cable 20 to which cables 21 for power supply are added. There is also, at ground level, a control member 22 connected by a cable 23 with three conductors to the motor 7 to rotate the latter, at very slow speed, in order to give the desired inclination to the assembly supported by the mast 2.
Un bouton poussoir 24, également au niveau du sol, est relié par un câble 25 à deux conducteurs à la boîte de relais 18. Cette dernière est elle-même raccordée par deux câbles 26, 27 à l'appareil photographique 11. Le même bouton poussoir 24 peut servir à commander la fermeture successive de deux relais, l'un commandant la prise de vue et l'autre l'avancement de la pellicule. Ces moyens de commande dépendent de l'appareil photographique utilisé; comme on le sait certains appareils sont munis d'un moyen automatique d'avancement de la pellicule.A push button 24, also at ground level, is connected by a cable 25 with two conductors to the relay box 18. The latter is itself connected by two cables 26, 27 to the camera 11. The same button pusher 24 can be used to control the successive closing of two relays, one controlling the shooting and the other advancing the film. These control means depend on the camera used; as we know some devices are equipped with an automatic means of advancing the film.
De préférence, l'appareil photographique 11 est du type à mise au point automatique après qu'il ait été orienté sur le point 15, 15', etc... surveillé par la caméra de télévision 10 et où se trouve approximativement le sujet à photographier.Preferably, the camera 11 is of the autofocus type after it has been oriented at point 15, 15 ′, etc., monitored by the television camera 10 and where the subject to be located approximately is located. photograph.
Comme on l'a dit, l'orientation de l'appareil photographique 11 pourrait être télécommandée, à l'aide d'un moteur 7 et d'un organe de commande 22 supplémentaires. L'écran de télévision 19 et l'organe de commande 22 sont raccordés, au sol, à une source d'énergie électrique convenable, non représentée. Les moyens de contrôle et de commande décrits ci-dessus sont susceptibles de nombreuses modifications, selon le degré de perfectionnement que l'on veut y apporter à l'aide des moyens de télécontrôle et de télécommande disponibles. Par exemple, l'invention n'exclut pas l'emploi de moyens de télécommande sans fil, comme on en utilise pour la télécommande des modèles réduits d'automobiles ou d'avions.As said, the orientation of the camera 11 could be remote controlled, using a motor 7 and an additional control member 22. The television screen 19 and the control member 22 are connected, on the ground, to a suitable source of electrical energy, not shown. The control and command means described above are susceptible to numerous modifications, depending on the degree of improvement which it is desired to bring to it by means of the available remote control and remote control means. For example, the invention does not exclude the use of wireless remote control means, as is used for the remote control of model cars or planes.
Ces derniers moyens conviennent plus particulièrement pour le second aspect de l'invention illustré par la figure 4.These latter means are more particularly suitable for the second aspect of the invention illustrated in FIG. 4.
Dans ce cas le moyen d'élévation à partir du sol est un ballon captif 28 retenu au sol par un câble 28A; bien entendu ce dernier peut servir à guider les câbles de télécommande et de télécontrôle quand des moyens sans fil ne sont pas utilisés intégralement. De préférence, le ballon 28 est du type à gaz chauds produite à partir d'une bouteille de propane liquéfié 29, de façon connue. Cette bouteille 29 est posée sur une plaque porteuse 30 sous laquelle est suspendu le support 4 en C, mais l'organe porteur 9 a pivoté sous l'action du moteur 7 autour de la branche 4B pour se trouver avec la caméra 10 et l'appareil 11 à une première position, entre les branches 4A, 4B, alors que, sur la figure 1, cet organe porteur 9 se trouve à sa seconde position, en dehors des branches 4A, 4B.In this case the means of elevation from the ground is a captive balloon 28 retained on the ground by a cable 28A; of course the latter can be used to guide the remote control and telecontrol cables when wireless means are not used in full. Preferably, the balloon 28 is of the hot gas type produced from a liquefied propane bottle 29, in a known manner. This bottle 29 is placed on a carrier plate 30 under which the support 4 at C is suspended, but the carrier member 9 has pivoted under the action of the motor 7 around the branch 4B to be with the camera 10 and the device 11 in a first position, between the branches 4A, 4B, while, in FIG. 1, this carrier member 9 is in its second position, outside the branches 4A, 4B.
La suspension sous la plaque porteuse 30, à l'aide de la branche 4A, se fait aussi par l'intermédiaire d'un embout vertical 5, mais au moyen d'un moteur d'orientation 31, identique par exemple au moteur 7, disposé verticalement, pour permettre l'orientation de l'ensemble sur 360º autour d'un axe vertical. Dans l'exemple de la figure 1, si le mât 2 n'était pas orientable à l'aide du bras d'orientation 3, un moteur d'orientation pourrait aussi être interposé entre le mât 2 et l'embout 5. Le fonctionnement du dispositif est le suivant.The suspension under the carrier plate 30, using the branch 4A, is also done by means of a vertical tip 5, but by means of an orientation motor 31, identical for example to the motor 7, arranged vertically, to allow orientation of the assembly over 360º around a vertical axis. In the example of FIG. 1, if the mast 2 was not orientable using the orientation arm 3, an orientation motor could also be interposed between the mast 2 and the end piece 5. The operation of the device is as follows.
On règle d'abord l'emplacement du point 15, où se coupent la ligne de visée 12 de la caméra 10 et la ligne de prise de vues 13 de l'appareil photographique 11 en fonction de l'éloignement estimé ou mesuré du sujet à photographier, en orientant l'appareil 11 (quand ce réglage n'est pas télécommandé comme expliqué plus haut), puis on élève le mât 2 ou on laisse monter le ballon 28 à la hauteur convenable. On vérifie le cadrage du sujet sur l'écran de télévision 19, on corrige éventuellement à l'aide de l'organe de commande 22 et du bras d'orientation 3 (ou du moteur d'orientation 31), puis on déclenche l'appareil photographique 11 au moyen du bouton poussoir 24. The location of point 15 is first adjusted, where the line of sight 12 of the camera 10 and the line of view 13 of the camera 11 intersect according to the estimated or measured distance from the subject to photograph, by orienting the camera 11 (when this setting is not remote-controlled as explained above), then the mast 2 is raised or the balloon 28 is allowed to rise to the appropriate height. The framing of the subject is checked on the television screen 19, it is possibly corrected using the control member 22 and the orientation arm 3 (or the orientation motor 31), then the camera 11 by means of push button 24.
