3D projection quality evaluation system that can reflect the viewing effect of the entire auditorium

Abstract

The invention is applicable to the 3D projection display technical field, provides a 3D projection quality evaluation system capable of reflecting the viewing effect of a whole cinema. The system comprises a projector for projecting a test image on a metal screen; multiple 3D glasses which are distributed at multiple preset detection locations in the cinema and are respectively used for receiving the test image reflected by the metal screen at own detection locations; multiple first color and brightness testers; multiple second color and brightness testers; a quality parameter evaluation module which are connected with the multiple first color and brightness testers and second color and brightness testers, are used for carrying out weighted processing to the color and brightness parameters detected by the first and second color and brightness testers and making a quality evaluation result. According to the system of the invention, the 3D glasses worn by the audience in viewing collect the projection quality parameters at multiple locations; the 3D projection quality is evaluated by software; the projection quality of the 3D projection system in the whole cinema can be learned visually; corresponding adjustment is convenient; and the viewing quality of a user is ensured.

Description

technical field [0001] The invention belongs to the technical field of 3D projection display, and in particular relates to a 3D projection quality evaluation system that can reflect the viewing effect of the entire auditorium. Background technique [0002] The advent of 3D movies has undoubtedly given the audience a new sensory experience, three-dimensional visual impact, and powerful fighting scenes, adding more excitement to the movie. [0003] If the screening quality can be evaluated and then adjusted accordingly according to the evaluation results, the audience's viewing experience can be better guaranteed. At present, there is a projection quality evaluation technology that uses the position close to the projector as the 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 me...

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
