Abstract

The embodiment of the invention discloses a detection method and a detection apparatus of image arrangement parameters of a display device, a device and a storage medium. The method comprises the following steps: based on a preset image generation algorithm and a plurality of preset image arrangement parameters, generating periodically varying pattern images arranged in an array form, and pushingthe pattern images to a display device for displaying; driving an image acquisition device to collect detection images displayed after the pattern images pass through a grating film, and acquiring thecollected detection images; identifying a target array region, where a moire fringe satisfying a preset condition is, from each array region of the detection images, and taking the preset image arrangement parameters corresponding to the target array region as target image arrangement parameters of the display device. Through the method, the apparatus, the device and the storage medium provided by the technical scheme above, detection precision of the image arrangement parameters is improved, and implementation of automation and requirements of yield fast generation are facilitated.

Description

technical field [0001] Embodiments of the present invention relate to glasses-free 3D technology, and in particular to a method, device, device, and storage medium for detecting layout parameters of a display device. Background technique [0002] With the development of science and technology, 3D display technology has become a research focus in the field of display. Among them, the realization of naked-eye 3D display effect provides great convenience for users to watch images and videos. When performing naked-eye 3D display, the display effect of the display screen mainly depends on the accuracy of layout parameters (such as layout cycle and grating slope). Therefore, in order to improve the naked-eye 3D display effect, the detection and Calibration becomes the most important link in the calibration process of naked-eye 3D display devices. [0003] At present, manufacturers of naked-eye 3D display devices mainly use parameter detection systems to manually detect their para...
