The detailed description of the invention of embodiment one, therefore the most detailed part, Ke Yican in the description that the present embodiment is for step 201-step 203
See the related description in previous embodiment one, do not repeat at this.
The split screen image that can directly use shooting to obtain in the embodiment of the present invention is combined, and obtains complete scene effect
Really image, but in practice, during test, photographic head and splicing test equipment cannot be substantially parallel, the split screen image therefore obtained
Ratio is the most different, so every split screen image is in addition to the split screen content that splicing test equipment shows, also can photograph part unnecessary
Image contributions splicing effect.In this case the scene effect figure obtained is as shown in Figure 8.In this case, tester
Or it is difficult to light exact p-value result.
For these problems, the embodiment of the present invention, can be for before split screen image sets is combined into scene effect image
Split screen image is optimized, and removes unnecessary part.
Step 204, obtains arbitrary split screen image；
Step 205, receives the rectification position for described split screen image；
Step 206, carries out perspective transform process according to described rectification position for split screen image；
Step 207, the split screen image sets after described perspective transform being processed is combined into scene effect image.
In embodiments of the present invention, the split screen image of photographic head shooting is intercepted, only focused on splicing test equipment
The split screen content of display, and the split screen image tilting certain angle distortion is carried out correction process, make the scene being finally spliced into
Effect image is more prone to distinguish, eliminates tester and repeatedly adjusts photographic head and the work finally repeatedly confirmed image,
Improve work efficiency.
Split screen image after correction process can be as it is shown in figure 9, eliminate except splicing in split screen image after correction process
Other superfluous content outside the split screen content that test equipment shows.
In a preferred embodiment, in order to not increase operation easier, acquisition can be increased on PC end software interface
The step of splicing four apex coordinates of test equipment, as long as tester is before performing test, opens any one photographic head and claps
The split screen image taken the photograph, double-clicks four summits of telescreen successively, can get rectification coordinate position, four as shown in Figure 10
At red point.
The picture of shooting every time, according to four apex coordinates of the telescreen got, is carried out at perspective transform by instrument
Reason, corrects deformation picture, and the image before and after rectification is as shown in figure 11, it can be clearly seen that, the image after rectification only remains
