Multiple cameras are used to obtain the first difference between first position and the second position and the first image and the second image,
Therefore the cost of camera can be reduced.
Also, since the embodiment of the present invention uses single camera, solve due to being shot using multiple cameras
When object, the parameter (such as camera lens curvature, brightness) of multiple cameras has differences, and influences the synthesis essence of terminal device shooting
The problem of accuracy, shooting effect to influence terminal device so that the image of shooting is more accurate.
Further, offer object distance of embodiment of the present invention measurement method can be by obtaining object away to realize background
