To there is two kinds of shape informations, the first is the M stripe width informations for obtaining M stripe light；Second is to obtain M stripes
Character pattern information.
Below, the situation of the M stripe width informations of the first acquisition M stripe light is described in detail first.
When fringe structure light is transmitted on an object under test using a striated structure light source, the striated structure light source is just
The different fringe light of a plurality of width of fringe is formed, wherein, K bars in M stripe light in the different a plurality of fringe light of width
The K stripe width informations of fringe light, moreover, having J stripe light in M stripe light in the different more stripes of width
J stripe width informations, wherein, do not have between the J stripes light and K stripe light overlapping.
As shown in Fig. 2 because the information of the fringe structure light of acquisition is different, for example, in first area A, bar is obtained
Line width information is followed successively by（2,4,7,3,5）Striped, then, it is determined that width of fringe be 7 striped when, it is possible to according to
The stripe close on before width of fringe be 2,4, width of fringe below is 3,5, so that it is determined that the striped, certainly, is
Be able to confirm that more accurate striped, can also more several stripes of increase forwards, backwards information, such as, in second area B, obtain
Width of fringe information is obtained to be followed successively by（1,3,6,2,9,8,7）, then, it is possible to confirmed according to front and rear three groups of width of fringe information
Width information is 2 stripe information.
Pass through above-mentioned example, it is possible to which the technology for overcoming the striped of the brightness such as prior art medium-width to be difficult to confirm is asked
Topic.
Second acquisition be M stripes character pattern information in the case of be described in detail.
When fringe structure light is transmitted on an object under test using a striated structure light source, striated structure light source just shape
Into with figuratum fringe light, specifically, equally spaced setting has center on any one stripe light in M stripes
Corresponding identical patterns, the pattern are used for identifying the fringe light, and the pattern in M stripe light in the stripe of arbitrary neighborhood two is not
Identical.
As shown in figure 3, by taking the character pattern wherein in a stripe as an example, such as, it is equally spaced in this stripe
The pattern of equilateral triangle type is set, can set square, five-pointed star etc. centrosymmetric respectively in two adjacent stripes
Pattern.
Specifically design be spaced when, it is necessary to consider two kinds of factors, first, with no more than the minimum thing for needing to differentiate in scene
The width of body（Or height）It is advisable, to ensure that existing striped has pattern to be detected in same subject again.Second,
Strip length between pattern should not be too small, because striped has the function that to point the direction, the too short then walking direction of length is easy
Error.
It is above-mentioned that different character patterns is set in more stripes can be that different patterns is all set in every stripe,
Certainly, can also be corresponding by the insertion in order of the pattern periodicity in pattern set in order to reduce used number of patterns
Striped in.That is, it can periodically repeat to set pattern on striped.It is, of course, also possible to more stripes are carried out
Classification, there is a reference stripe per one-level striped, only pattern, the reference stripe of multistage striped can be set in reference stripe
On different character patterns is also all set.
Specifically for the design of pattern, mainly with simple, discrimination original text is designed for principle, is so easy to striped quilt
Readily detect or recognize, moreover, different patterns is not easy to obscure.Meanwhile for pattern design requirement it is optimal be
Using centrosymmetric pattern, the so easy accurate center sub-pixel location for calculating pattern, so as to improve the essence of disparity computation
Degree.
By way of setting character pattern, also solve existing fringe structure light in more stripes above-mentioned and easily go out
Mistake, the technical problem that workload is big is caused, moreover, the mode encoded using the pattern on striped to striped, remains bar
The directional characteristics of line, improve the robustness of decoding patterns.
It is error-prone so as to not allow when confirming striped order according to the shape information of more stripes by above two, connect
, according to the width information of striped or character pattern information, can confirm that the positional information of striped.It is specific as follows：
Before the M stripe width informations of above-mentioned acquisition M stripe light, this method also includes：

Whether M second place information of the M stripe light in light is identical with M standard location information of M stripe information, in not phase
Meanwhile determine M positional information of the M stripe light.
The positional information for the M stripes for specifically judging to obtain changes relative to whether the standard location information of M stripes has
Become, when there is change, according to the positional information of the striped of change, to determine the positional information of current fringes.
Then, based on the M positional information, it is determined that with the distance between normal place difference；According to the range difference, it is determined that
With the depth information of the object under test.
In a particular embodiment, if it is determined that obtaining the M stripes in a plurality of fringe light corresponding to M stripe information
After whether M second place information of light is identical with M standard location information of M stripe information, if obtaining identical
As a result, then illustrate that depth information is not present in the object under test, if obtaining the result differed, it is deep to illustrate that the object under test is present
Information is spent, then, according to the distance between the positional information of the striped with different width of fringe information and standard location information
Difference, the depth information of object under test is calculated by certain algorithm.
Similarly, based on the M stripe character pattern information, more stripes corresponding with the M stripe pattern-informations are judged
