Technical scheme in the embodiment of the present application is solve above-mentionedly easily to make mistakes in the process of stripe order recognition determining fringe structure light, and therefore, there is the technical matters that workload is large, general thought is as follows:
When utilizing a striated structure light source, fringe structure light is transmitted on an object under test, and in the reflection through object under test, when a projection surface forms the first image, obtain the M stripe information of the M stripe light be distributed on this object under test, wherein, in this M bar shape information, N bar shape information is had to be different, wherein, M be more than or equal to 2 integer, N be less than or equal to M and be more than or equal to 2 integer.Then, based on this M bar shape information, M positional information in the M stripe light in many stripe light corresponding with this M bar shape information is determined; Finally, based on this M positional information, can determine that the depth information of object surveyed by this band.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
The method of a kind of information processing that the embodiment of the present application provides is applied in an electronic equipment, and this electronic equipment can be specifically that the depth camera of structure based light is first-class, and as shown in Figure 1, the method specifically comprises:
S101, when utilizing a striated structure light source, fringe structure light is transmitted on an object under test, and through the reflection of described object under test, when a projection surface forms the first image, obtain the M bar shape information of the M stripe light be distributed on described object under test, wherein, there is N bar shape information not identical in described M bar shape information, wherein, M be more than or equal to 2 integer, N be less than or equal to M and be more than or equal to 2 integer;
S102, based on described M bar shape information, determines M positional information of the M stripe light in described many stripe light corresponding with described M bar shape information;
S103, based on a described M positional information, determines the depth information of described object under test.
Concrete, in S101, obtain the M bar shape information being distributed in the M stripe light that described band is surveyed on object specifically can have two kinds of shape informations, and the first is the M stripe width information obtaining M stripe light; The second is the character pattern information obtaining M stripe.
Below, first the situation that the first obtains the M stripe width information of M stripe light is described in detail.
When utilizing a striated structure light source fringe structure light to be transmitted on an object under test, this striated structure light source just forms the different striped light of many stripe width, wherein, the K stripe width information of K stripe light in M stripe light in this many stripe light that width is different, and, in many stripe that width is different, in M stripe light, there is the J stripe width information of J stripe light, wherein, do not have overlapping between this J stripe light with K stripe light.
As shown in Figure 2, because the information of the fringe structure light obtained is different, such as, at first area A, obtain width of fringe information and be followed successively by (2, 4, 7, 3, 5) striped, so, when determining that width of fringe is the striped of 7, can be just 2 according to the width of fringe before closing on this stripe, 4, width of fringe is below 3, 5, thus determine this striped, certainly, in order to striped more accurately can be confirmed, the information of a few stripe can also be increased forwards, backwards more, such as, at second area B, obtain width of fringe information and be followed successively by (1, 3, 6, 2, 9, 8, 7), so, just can confirm that width information is the stripe information of 2 according to three groups, front and back width of fringe information.
By above-mentioned example, the striped that just can overcome the brightness such as prior art medium-width is difficult to the technical matters confirmed.
When the second obtain be the character pattern information of M stripe be described in detail.
When utilizing a striated structure light source fringe structure light to be transmitted on an object under test, striated structure light source just forms the figuratum striped light of band, concrete, on any stripe light in M stripe, equally spaced setting has identical patterns corresponding to center, this pattern is used for identifying this striped light, and the pattern in M stripe light in arbitrary neighborhood two stripe is not identical.
As shown in Figure 3, for the character pattern in a wherein stripe, such as, the equally spaced pattern arranging equilateral triangle type in this stripe, two adjacent stripe can arrange square respectively, the centrosymmetric pattern such as pentagram.
Specifically when designing interval, needing consideration two kinds of factors, the first, being advisable, to ensure that in same subject existing striped has again pattern to be detected to be no more than in scene the width (or height) needing the smallest object differentiated.The second, the strip length between pattern should not be too little, because striped has the effect pointed the direction, length is too short, and walking direction is easily made mistakes.
It is above-mentioned that in many stripe, arrange different character pattern can be all arrange different patterns in every stripe, certainly, in order to reduce used number of patterns, and also can by the corresponding striped of insertion in order of the pattern period in pattern set.That is, can periodically repeat to arrange pattern on striped.Certainly, can also carry out classification to many stripe, every one-level striped has a reference stripe, only can arrange pattern in reference stripe, the reference stripe of multistage striped also all arranges different character pattern.
The concrete design for pattern, mainly with simply, discrimination original text is that principle designs, and be convenient to striped like this and be easy to detect or recognize, and different patterns is also not easily obscured.Meanwhile, for pattern designing requirement optimum be adopt centrosymmetric pattern, the center sub-pixel location of so easy accurate Calculation pattern, thus improve the precision of disparity computation.
By the above-mentioned mode arranging character pattern in many stripe, also solve existing fringe structure light easily to make mistakes, cause the technical matters that workload is large, and, utilize the mode that the pattern on striped is encoded to striped, remain the directional characteristics of striped, improve the robustness of decoding patterns.
By above-mentioned two kinds of shape informations according to many stripe thus confirm striped order time be not easy to make mistakes, then, according to width information or the character pattern information of striped, the positional information of striped can be confirmed.Specific as follows:
Before the M stripe width information of above-mentioned acquisition M stripe light, the method also comprises:
Obtain M standard location information of M stripe light.Concrete this M standard location information is specially and obtains after smooth flat reflects when not having object under test.
Then, in S102, based on this M stripe width information, judge that whether M second place information of the M stripe light in many stripe light corresponding with this M stripe information is identical with M standard location information of M stripe information, when not identical, determine M positional information of this M stripe light.
Specifically judging whether the positional information of the M stripe obtained changes relative to the standard location information of M stripe, when changing, according to the positional information of the striped of change, determining the positional information of current fringes.
Then, based on this M positional information, the range difference between this normal place is determined; According to this range difference, determine the depth information with this object under test.
In a particular embodiment, if after judging that whether M second place information of the M stripe light obtained in many stripe light corresponding to M stripe information is identical with M standard location information of M stripe information, if obtaining identical result, so illustrate that this object under test does not exist depth information, if obtain not identical result, illustrate that this object under test exists depth information, then, according to the distance difference had between the positional information of striped of different width of fringe information and standard location information, the depth information of object under test is calculated by certain algorithm.
In like manner, based on this M stripe character pattern information, judge that whether the 3rd positional information of the M stripe light in many stripe light corresponding with this M stripe pattern-information is identical with M article of standard location information of M stripe information; When difference, determine M positional information of this M stripe light.Thus based on this M positional information, determine the range difference between this standard location information, according to range difference, determine the depth information of this object under test.
