Description

TECHNICAL FIELD

[0002] Since the binocular near-eye display detection needs to simulate the object distance range of 0.2 meters to infinity, the object distance range is large, and the existing method generally uses an industrial camera and an industrial lens to obtain an image (as shown in the figure), the existing binocular near-eye display detection system generally uses an industrial camera with low pixels and an industrial lens, and the industrial lens cannot simulate multiple object distance ranges, and can only detect a specific object distance; in addition, the existing binocular near-eye display detection system cannot realize software control of simulated object distance switching, and the use scene is single; in addition, the existing binocular near-eye display detection system cannot adjust the binocular interpupillary distance, and cannot adapt to detection applications of various interpupillary distances. Therefore, the application of the binocular near-eye display detection system which can be software controlled and electrically switched to simulate the object distance can well solve the pain points of the prior art and facilitate detection and production.

The screw rod assembly and the guide rail assembly in the above structure are all existing purchased components, and the frame is also prior art, so the specific structure of the screw rod assembly and the guide rail assembly and the structure connected with the frame are not described in detail, and the mounting structure of the lens on the frame is also prior art and is not the improvement point of the present application, so the specific structure is not described in detail.
