Technical Field

The invention relates to the field of data processing systems and methods special for supervision, in particular to a binocular fusion failure judgment method, a fusion function detection method and a system thereof.

Background

The fusion function detection and training is to project 2 visual targets to the left and right eyes of the testee respectively, so that the brain of the testee can combine the images of the 2 visual targets. The distance between the 2 sighting marks is changed until the brain fusion of the testee fails, 2 independent sighting mark images are formed, and the fusion range of the testee can be determined according to the relative displacement of the 2 sighting marks.

The traditional fusion function detection mainly comprises two detection modes, wherein one mode is that 2 similar visual targets with recognizable difference are projected to eyes of a testee, and then 2 graphs with different characteristics are seen according to subjective reflection of the testee to judge fusion failure. The method has the problems that the real image is not fed back faithfully subjectively or how to match the inspection process is not understood, and the like, so that the inspection result is inaccurate. For example, when the user wants to obtain a good examination result, it is possible to feed back that only one image is seen after 2 images have been viewed.

The other method is that 2 identical pictures or two visual targets with depth characteristics after image combination are projected to eyes of a tested person, and then the depth graph after image combination can be seen according to subjective reflection of the tested person or the depth graph after image combination can be objectively and correctly identified to judge the image fusion failure. This approach requires that the user has depth perception as a precondition, and depth perception as a level III function for binocular single vision, which is not possessed by some users having the fusion function, so that the fusion range cannot be objectively checked without stereoscopic vision.
