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.
