Title:
METHOD AND APPARATUS FOR EVALUATING IMAGE ACQUISITION ACCURACY, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/253827
Kind Code:
A1
Abstract:
The present disclosure provides a method for evaluating the image acquisition accuracy of a Demura device, comprising: controlling a display panel to display a detection screen, the detection screen comprising a plurality of test point patterns at intervals; performing image acquisition on the detection screen using the Demura device to obtain an image to be processed corresponding to the detection screen, the size and shape of said image being the same as those of the corresponding detection screen; and determining the image acquisition accuracy of the Demura device according to the difference between the position of each test point pattern in the detection screen and a corresponding position in said image. The present disclosure also provides an apparatus for evaluating the image acquisition accuracy of a Demura device, an electronic device, and a non-transitory computer-readable storage medium.
