Abstract
A method, a system, a processing device and a computer storage medium for evaluating a viewpoint density are provided. The method includes: acquiring a quantity of viewpoints of a display panel; comparing a size of an image spot radius of each viewpoint and image point spacing between the viewpoint and an adjacent viewpoint, and selecting one viewpoint as a reference viewpoint, calculating a crosstalk value between another viewpoint except the reference viewpoint and the reference viewpoint; and evaluating a viewpoint density for the auto-stereoscopic display according to the comparison of the size of the image spot radius of each viewpoint and the image point spacing between the viewpoint and the adjacent viewpoint and the calculated crosstalk value between the another viewpoint and the reference viewpoint.
