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

Abstract

The invention is applicable to the technical field of 3D projection display, and provides a projection quality evaluation system of a 3D projection system based on multi-point detection. Including: a projector, used to project test images to the metal screen; multiple 3D glasses, distributed in multiple preset detection positions in the auditorium, respectively used to receive test images reflected by the metal screen at their own detection positions; multiple The first color brightness tester; a plurality of second color brightness testers; a quality parameter evaluation module, connected with a plurality of first and second color brightness testers, for detecting the first and second color brightness testers The color brightness parameters are averaged to make a quality evaluation result. The present invention uses the 3D glasses worn by the audience to collect projection quality parameters at multiple positions, and then uses software to evaluate the 3D projection quality, so that the projection quality of the 3D projection system in the entire projection hall can be intuitively understood, and it is convenient to make corresponding adjustments. It can guarantee the viewing quality of users.

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
