Projection quality evaluation system for 3D projection system based on multi-point detection

Abstract

The invention is applied to the technical field of 3D projection display, and provides a projection quality evaluation system for a 3D projection system based on multi-point detection. The projection quality evaluation system comprises a projector, a plurality of 3D glasses, a plurality of first colour brightness testers, a plurality of second colour brightness testers and a quality parameter evaluation module, wherein the projector is used for projecting a test image to a metal screen; the plurality of 3D glasses are distributed at multiple detection positions preset in a video hall and respectively used for receiving the test image reflected by the metal screen at the self detection positions; and the quality parameter evaluation module is connected with the plurality of first and second colour brightness testers and used for averaging colour brightness parameters detected by the first and second colour brightness testers and making a quality evaluation result. According to the invention, projection quality parameters are acquired at multiple positions through the 3D glasses worn by audiences while watching a film; 3D projection quality is evaluated by utilising software; therefore, the projection quality of the 3D projection system in the whole video hall can be known intuitionally; corresponding adjustments can be made conveniently; and the film watching quality of users can be ensured.

Description

technical field [0001] The invention belongs to the technical field of 3D projection display, and in particular relates to a projection quality evaluation system of a 3D projection system based on multi-point detection. Background technique [0002] The advent of 3D movies undoubtedly gave the audience a brand-new sensory experience. The three-dimensional visual impact and powerful fighting scenes added more excitement to the movie. [0003] And if it is possible to evaluate the projection quality and then make corresponding adjustments based on the evaluation results, the audience's viewing experience can be more guaranteed. At present, there is a projection quality evaluation technology that uses the position close to the projector as a test point to receive the test image reflected by the metal screen through 3D glasses, but the test position of this technology is fixed, and the evaluation result can only represent the viewing effect of the fixed position. When each area...

Problems solved by technology

At present, there is a projection quality evaluation technology that uses the position close to the projector as a test point to receive the test image reflected by the metal screen through 3D glasses, but the test position of this technology is fixed, and the evaluation result can only represent the viewing effect of the fixed position. When each area of ​​the metal screen has a large deviation in the reflectivity and color reproduction rate of the projected light, it is likely that the viewing effect at this fixed test point is good but the effect at other positions is poor, especially when the area of ​​the projection hall is large. When it is larger, this technology cannot truly reflect the projection quality of the entire cinema
