Be S
kThe energy in zone, it changes along with the variation of masterplate T.If the excursion of T is less,
Also be approximately constant.In order to make D (S
k, T) minimum, then
Should be maximum.Adopt herein the normalization cross correlation algorithm (Normalized Cross Correlation NCC) eliminates the mistake coupling that luminance difference causes, correlation function can be expressed as:
E (S wherein
k) and E (T) be respectively S
kAverage gray value with T.When C (Δ x, Δ y) is maximum, D (S
k, T) minimum can be thought (x
L, y
L) and point (x
L+ Δ x, y
L+ Δ y) coupling.Δ x, Δ y are respectively horizontal parallax and the vertical parallax between two width of cloth images.For parallel vidicon recited above system, vertical parallax is approximately 0, and horizontal parallax can be expressed as:

Because the position of spacing, angle and the vertical direction of the two dimensional image that obtains by step 201 when mobile cameras can't accurately be controlled, and therefore need handle by the conversion process module.Comprise the steps:
Step 204a: be as the criterion with piece image wherein, another width of cloth image is carried out the scan line registration process, obtain two width of cloth images through corresponding right and left eyes after the scan line registration process;
Because people's eyes horizontal level height is identical, therefore there is not the difference of vertical direction during imaging in the scene content of being watched on binocular.And at mobile cameras in the moving process of another angle shot, may have the inconsistent of vertical direction, the picture line registration process realizes the vertical direction alignment of left and right sides stereo-picture to scene content.Compare by stereo-picture reconstruction of three-dimensional model of place or range finding with other and obtain depth information by stereoscopic photograph, needed precision is lower.
The picture line registration process can be in the following way: in the scene overlay region of left and right sides image, create two or more search columns on the left side image and the right image, and each hurdle of image resolved into a plurality of grayscale sub-image according to color component, adopt a kind of matching algorithm that each point in each subimage search column is mated and calculate vertical offset, adjust alignment two width of cloth images thereby utilize these vertical offset to be extrapolated to entire image.

Reset maximum disparity and be because at mobile cameras in the process of another angle shot, can mobile spacing too small, thereby make that the parallax of two photos is less, third dimension is not strong when causing stereoscopic photograph to show, or the spacing that moves is excessive, cause parallax excessive, cause easily and watch fatigue.As shown in Figure 8, it is as follows to reset the processing procedure concrete steps of maximum disparity:
A: at first two width of cloth images after the scan line alignment are carried out the solid coupling, obtain the disparity map of left image correspondence;
B: obtain the maximum disparity value in the disparity map;
C: the best parallax value that will pre-set is divided by the maximum disparity value that obtains, thereby obtains the zoom factor of parallax;
D: utilize this zoom factor that the parallax of every bit in the disparity map is carried out convergent-divergent;
E: utilize parallax and left image reconstruction right image behind the convergent-divergent;
F: stereo-picture is right preferably thereby obtain effect.

Step 304A; At first need to cut apart and obtain each target in the image, and each target incorporated into be display foreground or background.
Display foreground and background can adopt based on the iterative method of threshold value to be cut apart, and iterative method is based on optimization thought, and its flow process such as Figure 10 show that step is as follows:
A: obtain the maximum gradation value and the minimum gradation value of image, be designated as Z respectively
MAXAnd Z
MIN, make initial threshold T
0=(Z
MAX+ Z
