Stereo display equipment, and correction method, device and system thereof

Abstract

The invention discloses stereo display equipment, and a correction method, a device and a system thereof which are used for improving the light splitting effect of the grating of the stereo display device. The correction method comprises the steps as follows: camera compensation parameters of the stereo display equipment are sent to the stereo display equipment; the stereo display equipment applies the camera compensation parameters and regulates pixel compensation parameters; the camera compensation parameters applied by the stereo display equipment is obtained, and a plurality of groups of image pairs consisting of left eye images and right eye images and displayed during the process of the pixel compensation parameters are regulated; a change law in the process of the pixel compensation parameters and regulated by the image pairs on the stereo display equipment is obtained; and according to the change law of the image pairs, a pixel compensation parameter is selected as a correction objective value. According to the embodiment of the invention, through regulating the camera compensation parameters and the pixel compensation parameters, the stereo display equipment can obtain an idea light splitting effect, so that high-definition stereo images are provided for viewers.

Description

technical field [0001] The invention relates to stereoscopic display technology, in particular to a stereoscopic display device and its calibration method, calibration device and calibration system. Background technique [0002] Stereoscopic display technology uses parallax features to present realistic stereoscopic images with spatial depth information. The naked-eye stereoscopic display device needs to install a grating in front of a display panel (panel), and provide at least two parallax images displayed on the display panel to the left eye and the right eye of the viewer respectively through the grating. [0003] In the naked-eye stereoscopic display technology, in order to enable the viewer to watch the ideal stereoscopic image in a relatively large area, the camera is used to track the position of the viewer, and the ideal stereoscopic image is provided to the viewer by adjusting the parallax image at any time. . [0004] For stereoscopic display devices equipped wi...

Problems solved by technology

[0004] For stereoscopic display devices equipped with cameras, although the cameras and display panels will be calibrated at the factory, due to the limitations of the production process and installation process, it cannot be completely guaranteed that the installation positions of each display panel and camera are in a horizontal position. The direction or installation angle meets the corresponding design requirements

[0005] When there is an error in the installation position of the camera in the horizontal direction or in the installation angle, the position of the viewer acquired by the camera will not be very accurate, so that the viewer cannot see a clear image through the grating, resulting in stereoscopic display of the stereoscopic display device.
