It tells about in detail below and whether meets preset condition and determine usual practice really：
The left-eye image that stereoscopic display device is shown first be the first color image, eye image be the second color image, first Color image is different from the second color image.Optionally, the first color image be red (R), green (G), a kind of in blue (B) when, Second color image is red (R), the one of which in green (G), blue (B) in two kinds of remainder, that is, pixel is different.Here It is illustrated so that left-eye image is red image, eye image is green image as an example.
First camera and third camera shoot left-eye image respectively, referred to as left camera, second camera and the 4th Camera shoots eye image respectively, referred to as right camera.If there is crosstalk, then the image that left camera takes will not be complete Portion is red pixel, has part-green pixel；And the image that right camera takes will not be entirely green pixel, have portion Dividend color pixel.
A comprehensive value model value P can be set0, will be to the comprehensive evaluation value P of shooting picture1With comprehensive value model Value P0It is compared, if P1≥P0, then it is assumed that left camera takes complete red picture, and right camera photographed complete green picture.It calculates P1There are following two methods：
(1) if left camera and right camera photographed red image and the green image that stereoscopic display device is shown respectively, Processing unit handles red image and green image respectively.Here it is the image shot with left camera according to red pixel quantity It calculates, the image of right camera shooting is calculated according to green pixel quantity.
Number R1, the green pixel number G1 of red pixel in the left-eye image of left camera shooting are calculated, the right side is calculated and takes the photograph As the number G2 for the eye image Green pixel that head is shot, the number R2 of red pixel, left-eye image sum of all pixels and right eye The sum of all pixels of image is identical, is M, comprehensive evaluation value P1=(R1/M) * (G2/M), then according to the overall merit mark of setting Quasi- value P0, P0Value range be 0~1.Specific value can foundation：Camera is to red green sensitivity and ambient light The factors sets itself such as parameter of line, camera lens, for example：Light is too strong, lens aperture tune it is too big, the red photographed is caused to be lost Very, user can be by P at this time0Numerical value setting it is smaller.If P1≥P0, then it is assumed that left camera takes complete red picture, and the right side is taken the photograph As head photographed complete green picture.
(2) if there are non-black backgrounds in left-eye image and eye image, red pixel or green pixel can be influenced Evaluation, R or G pixel quantities is caused to become larger, whole result of calculation is had an impact.So in order to more accurate The quantity of R and B is calculated, it is further comprising the steps of that the method for being calculated as below can be used：
Figure step is scratched, by the difference of image pixel value, the edges of regions position of shooting picture image is determined, then plucks out The green image region in red image region and eye image in left-eye image.It then calculates red in red image region The number r1 of pixel, the number g1 of green pixel calculate the number g2 of green image region Green pixel, of red pixel Number r2, whole picture scratches figure image pixel number m, comprehensive evaluation value P1=(r1/m) * (g2/m), then according to the overall merit of setting Standard value P0, P0Value range be 0~1.If P1≥P0, then it is assumed that left camera takes complete red picture, and right camera photographed Complete green picture.
Moreover, it is judged that the method whether stereoscopically displaying images of acquisition meet preset condition is not limited to the above method, Also other various ways, such as：(1) image is calculating after being converted into extended formatting, and for example RGB is converted to after HSV It calculates again；(2) standard value (sum of all pixels in i.e. whole sub-picture) is adjusted at any time, is then being calculated according to the feature of image at any time Single pixel is in the ratio of whole image sum of all pixels.

21. a kind of computer readable storage medium, including with the stereoscopic display device with tracks of device, the first image collector It puts, first tracks the computer program that target, the second image collecting device, the second tracking target are used in combination, the computer Program can be performed to complete following steps by processing unit：
S1 indicates the first position when detecting that stereoscopic display device is traced into positioned at the first tracking target of first position The first stereoscopically displaying images that stereoscopic display device described in corresponding image acquisition device is shown；
S2 determine the corresponding image acquisition device in the first position to first stereoscopically displaying images whether meet Preset condition；
S3 when determining that first stereoscopically displaying images meet the preset condition, indicate the stereoscopic display device start with Track is located at the second tracking target of the second position and recorded for the first moment, and first moment starts for the stereoscopic display device T2 at the time of T1 or, first stereo-picture meet the preset condition at the time of tracking the second tracking target；
S4 indicates the corresponding image in the second position when detecting that stereoscopic display device traces into the second tracking target Harvester acquires the second stereoscopically displaying images that the stereoscopic display device is shown；
S5 determine the corresponding image acquisition device in the second position to second stereoscopically displaying images whether meet The preset condition,
S6 records the second moment T3 when determining that second stereoscopically displaying images meet preset condition；
S7 calculates the difference of the T3 and T1 or calculates the difference of the T3 and T2, and the difference is determined as tracking Row's figure delay time；
Wherein, first position is different from the second position.
