Abstract

The invention provides a visual test display system, which comprises an equipment information acquisition module used for acquiring parameter information of target display equipment and generating a corresponding retrieval code according to the parameter information; the visual testing module is used for acquiring visual testing items according to the retrieval codes based on a preset content database, performing visual testing and outputting a testing result; and the result display module is used for digitally analyzing the test result to obtain an analysis result, and visualizing the analysis result to obtain a graphical test result. According to the invention, the real visual effect of the human eyes is simulated by adopting the double probes, and the parameters of the display equipment are tested in a binocular stereo manner, so that the output parameters of the display equipment better accord with the visual comfort value of the human eyes.

Description

technical field [0001] The invention relates to the technical field of visual testing, in particular to a visual testing display system. Background technique [0002] At present, when performing visual testing of display devices, the testing process usually requires manual sending of instructions. Secondly, the testing process is limited to measuring optical parameters, and the related parameters of displayed stereo features are less measured, and monocular measurement is mainly used. This method relies on manual or mechanical transmission structure to spatially position the probe, so it does not support the detection of relevant parameters on the 3D display, the operation process is cumbersome, and the process is prone to delay, it is not real-time, and cannot be well reflected. The stereo vision effect of the human eye leads to poor reliability of the final test, such as the paper Yin,Ma,Zhong,etal.SLAM-Based Self-Calibration of a Binocular Stereo Vision Rig in Real-Time[J...
