Method for detecting stereo degree of autostereoscopic display by using random dot stereopsis
A stereoscopic display and random point technology, applied in the directions of instruments, optical components, optics, etc., can solve the problems of inability to accurately judge the stereoscopic degree of the free stereoscopic display screen, and unable to distinguish the true stereoscopic effect, so as to achieve the effect of intuitive detection and real-time judgment.

Embodiment Construction
[0052] Embodiments of the present invention will be further described in detail below in conjunction with the drawings and specific implementation methods. The embodiments of the present invention take a lenticular lens grating stereoscopic display as an example.
[0053] Generate a random dot map based on the resolution requirements for the stereogram of the lenticular display to be tested. Assuming that the lenticular lens grating display requires the resolution of the subsequent stereoscopic image to be N×M, then a random dot map with the same resolution of N×M and a grid structure with random gray values is generated. The resolution of each small square is A×B, which can be adjusted according to the comfort of human eyes, such as image 3 , Figure 4 and Figure 6 , Figure 7 shown. Figure 5 and Figure 8 respectively image 3 , 4 The group of random dot plots where and Figure 6 , 7 Two random point stereograms are obtained by combining the random point maps....
