Method, device and system for detecting crosstalk of parallax naked-eye 3D display

Abstract

The invention provides a method, a device and a system for detecting parallax glasses-free 3D display crosstalk, and relates to the technical field of 3D display. The method for detecting parallax glasses-free 3D display crosstalk comprises the following steps: making 3D display equipment display test images corresponding to viewpoints to form display images corresponding to the viewpoints, wherein each test image includes multiple viewpoint images; making image acquisition equipment acquire the display image corresponding to each viewpoint at the observation position of the viewpoint; comparing each display image with each color block image in a standard color block map to get crosstalk data of each display image, wherein the standard color block map includes multiple color block images of different gray values and crosstalk data corresponding to each color block image; and comparing the multiple pieces of crosstalk data corresponding to the multiple display images, and determining 3D display crosstalk of the 3D display equipment according to the comparison result. The display image corresponding to each viewpoint is acquired at the observation position of the viewpoint, and then, the display crosstalk of the 3D display equipment is determined through comparison.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to a method, device and system for detecting crosstalk in a parallax-type naked-eye 3D display. Background technique [0002] In the current parallax 3D display technology, the left and right eye images cannot be completely separated and accurately projected into the corresponding eyes, so that part of the left eye image information will enter the right eye, and part of the right eye image information will enter the left eye. , produce interference, this interference is called 3D crosstalk. Therefore, 3D crosstalk is an important parameter to measure the performance of a parallax 3D display device, and excessive 3D crosstalk will seriously affect the 3D experience. Therefore, the detection of 3D crosstalk is very important in the production and debugging process of the parallax 3D display device. [0003] Existing 3D crosstalk detection methods require special detection...
