The specific embodiment of embodiment one, therefore the present embodiment is for not detailed place in the description of step 201- step 203, Ke Yican
See the related description in previous embodiment one, i will not repeat them here.
It can be directly combined using the split screen image that shooting obtains in the embodiment of the present invention, obtain complete scene effect
Fruit image, but in practice, the split screen image that camera and splicing test equipment can not be substantially parallel, therefore obtain when test
Ratio is also different, so it is extra also to take part in addition to the split screen content that splicing test equipment is shown for every split screen image
Image contributions splicing effect.In this case the scene effect figure obtained is as shown in Figure 8.In this case, tester
Still it is difficult light exact p-value result.
For these problems, the embodiment of the present invention, can be for before split screen image group is combined into scene effect image
Split screen image optimizes, and removes extra part.
Step 204, arbitrary split screen image is obtained；
Step 205, the correction position for the split screen image is received；
Step 206, perspective transform processing is carried out for split screen image according to the correction position；
Step 207, by the perspective transform, treated that split screen image group is combined into scene effect image.
In embodiments of the present invention, the split screen image of camera shooting is intercepted, only focuses on splicing test equipment
The split screen content of display, and the split screen image for being tilted a certain angle distortion is subjected to correction process, make the scene being finally spliced into
Effect image is more easier to distinguish, eliminates the work that tester adjusts camera repeatedly and finally confirms repeatedly to image,
Improve working efficiency.
Split screen image after correction process can be as shown in figure 9, eliminate in split screen image after correction process except splicing
Other superfluous contents except the split screen content that test equipment is shown.
In a preferred embodiment, in order not to increase operation difficulty, acquisition can be increased on the software interface of the end PC
It is clapped as long as tester before executing test, opens any one camera the step of splicing four apex coordinates of test equipment
The split screen image taken the photograph successively double-clicks four vertex of video screen, can get correction coordinate position, and four as shown in Figure 10
At red dot.
