Abstract

The invention is suitable for the technical field of stereographic projection display, and provides a quality evaluation method, device and system of a stereographic projection device. The method comprises the following steps of: acquiring a corresponding projected image of the projection device on a projection screen via an image acquisition unit according to an evaluation item signal input by a user; and calculating a corresponding evaluated value of the evaluation item according to the acquired image, comparing the evaluated value with a pre-stored maximum deviation value, and displaying the evaluated value. With the method, the device and the system, a plurality of projected images are acquired in real time in a manner of time sharing according to different evaluation items, evaluation on relative offset or rotation of left and right light paths, evaluation on chroma luminance of the left and right light paths, evaluation on a crosstalk value of a left eye and evaluation on the crosstalk value of a right eye can be implemented, and compared with the prior art, the invention has the advantages of the evaluation range is wide, comprehensive analysis on factors influencing the quality of the stereographic projection device is facilitated, so that display quality of the stereographic projection device is improved, and uncomfortableness in viewing and influence on human eyes caused by phenomena, such as pseudo stereographic display and the like, can be reduced.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic projection display, and in particular relates to a quality evaluation method, device and system of stereoscopic projection equipment. Background technique [0002] Stereoscopic projection is an application of stereoscopic display. Its basic principle is to send the left eye image and right eye image with corresponding parallax to the observer's left eye and right eye respectively, so that the observer can perceive the stereoscopic depth and form a stereoscopic image. Parallax refers to the slight horizontal disparity in the retinal image of both eyes when the left and right eyes watch the same object from different positions and angles. When the left-eye image and right-eye image sent to the observer have relative offset or rotation, or there is inconsistency in chromaticity and brightness, or crosstalk occurs, the observer will experience uncomfortable viewing or pseudo-stereoscopic display,...
