Method and system for testing performance indexes of naked-eye 3D (three dimension) display equipment

Abstract

The invention discloses a method and a system for testing performance indexes of naked-eye 3D (three dimension) display equipment. The method and the system mainly solve the problem that the existing testing technology can be only used for timesharing equipment and light splitting equipment, can only evaluate performances by depending on local information, and is failed to test performances of the naked-eye 3D display equipment. The technical scheme for realizing the method and the system includes designing objective evaluation indexes characterizing the performances of the 3D display equipment and measuring methods for the objective evaluation indexes according to the features of a human vision system for sensing dimensional images; computing to obtain seven indexes of the display performances of the naked-eye 3D display equipment by means of images acquired by a stereo camera, namely the left-passage luminance crosstalk level CTL, the right-passage luminance crosstalk level CTR, the left-passage luminance contrast ratio CL, the right-passage luminance contrast ratio CR, the luminance difference value dL, the luminance contrast difference value dC and the moir strength index dM, and testing the performances of the naked-eye 3D display equipment according to the above indexes. The method and the system for testing performance indexes of the naked-eye 3D display equipment can be used for quality checking and classification of the naked-eye 3D display equipment and guarantees that quality of the naked-eye 3D display equipment sold in the market can meet the standard.

Description

technical field [0001] The present invention relates to the technical field of testing, in particular to the testing and objective evaluation of performance indicators of naked-eye 3D display equipment, including left channel luminance crosstalk CT L , right channel luminance crosstalk CT R , left channel brightness contrast C L , right channel brightness contrast C R , luminance difference dL, luminance contrast difference dC and moiré intensity index dM, which can be used for performance index testing, quality inspection and screening of naked-eye 3D display devices when they leave the factory. Background technique [0002] 3D display technology, that is, three-dimensional display technology, is a display technology that reproduces three-dimensional information in space. It transmits three-dimensional information to the human visual system through a dedicated display device, and the human brain forms three-dimensional perception based on the three-dimensional information...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the existing test methods are mainly aimed at 3D display devices with spectroscopic or time-sharing technology, and there is currently no effective and feasible method for testing the display performance indicators of naked-eye 3D display devices, which will lead to no objective indicators for naked-eye 3D displays when they leave the factory. The system can evaluate its display performance. Failure to use this type of product quality inspection, identification and screening will easily lead to the distribution market of products with substandard display quality, resulting in dizziness and other physical discomfort reactions during user use.
