Description

Combined analysis type VR glasses detection system
Technical Field
The utility model relates to VR projection lens module detection, in particular to a combined analysis type VR glasses detection system.
Background
The VR glasses 100 mainly comprise a VR projection lens and a VR screen, and the VR glasses 100 need to simulate an object distance range from 0.5 m to infinity, and the object distance range is large. For the existing method for detecting the VR glasses 100, an industrial camera and a special lens are generally used to form a human eye camera 200 at the exit pupil position of the VR glasses 100 to replace human eyes to obtain images (as shown in fig. 2), the form of the images on the industrial camera is analyzed through software, and the clear condition of the images is judged mainly according to an MTF data diagram, so that whether the position assembly of the VR projection lens and the VR screen meets the requirements is judged. Industrial cameras and special lenses must be very close to VR glasses 100, as well as the distance from human eye 300 to VR glasses 100 (as shown in fig. 1), which is detrimental to the AA process of VR glasses; in addition, the detection method using the eye camera 300 can only use one camera to detect the entire VR projection image plane, that is, the image displayed on the VR screen is projected onto the industrial camera through a special lens, and then the software selects a plurality of local areas of the image projected onto the industrial camera to analyze the sharpness thereof, so as to determine whether the assembly of the VR projection lens and the VR screen meets the standard, and the detection method has the following disadvantages: the number of the pixels of the whole screen is huge, but the resolution is ensured, so that the requirements on an industrial camera are very high, the cost is high, and the data transmission time is long because of the large data volume when the pixel data are transmitted to the background for analysis.
Thus, the present company adopts a local combinatorial analysis method to solve the above problems: the method comprises the steps that a plurality of areas, generally five areas, are directly selected on a VR screen, then images of each area are projected onto corresponding industrial cameras through corresponding combined analysis type VR glasses detection systems, data of the images on the five industrial cameras are collected through software, image forms are analyzed, and clear conditions of the images are judged, so that whether position assembly of the VR projection lens and the VR screen meets requirements or not is judged.
The method does not need to project the whole screen image, thus greatly reducing the resolution requirement for each industrial camera, greatly reducing the cost, reducing the total price of even five cameras compared with the previous one, reducing the data transmission quantity and greatly reducing the data transmission time. The application provides a combination analysis type VR glasses detection system.
