Methods and devices for detecting invariable visible displays, computer processing devices, and computer-readed recording materials

Abstract

The invention relates to a method and apparatus for detecting displays, devices, computer programs, and computer-readable recording media, in the field of display technology. The method includes the following steps: receive a command to detect a cylindrical lens for the target screen, the command to detect a cylindrical lens must include at least the target viewing point (101); respond to the detection command, obtain a captured view image of the target screen at the target viewing point, the target screen is a screen with a cylindrical lens on the light-emitting surface (102); when the view image includes the target content, use the view image as the view image (103); and based on the image parameters of the observation point image, the detection parameters are obtained to output the cylindrical lens on the target screen (104).
