Example Embodiment

[0023] Example one

[0024] figure 1 This is a schematic diagram of the naked eye 3D display calibration fixture provided in the first embodiment of the present invention. This embodiment can be applied to the case of 3D display module calibration. Such as figure 1 As shown, the naked eye 3D display correction fixture specifically includes:

[0025] The calibrated camera 110 is used to capture images displayed on the display screen that are interleaved according to the preset layout period and the preset layout period offset, the preset layout slope and the preset layout slope offset.

[0026] Specifically, the calibration camera 110 is placed on a sliding rail and can be slid relative to the sliding rail, and the optical axis of the calibration camera 110 is aligned with the center of the display screen. When the screen displays the images interwoven according to the design layout period and the preset layout period offset, the design layout slope and the preset layout slope offset...

Abstract

The embodiment of the invention discloses a naked eye 3D display correction fixture and correction method. The naked eye 3D display correction fixture comprises a correction camera, a sliding rail, atraction motor and a computer; the correction camera is used for shooting a red-blue intertwined image displayed on a display screen; the sliding rail is parallel to the normal of the plane of the display screen and is used for carrying the correction camera; the traction motor is arranged on the sliding rail and used for pulling the correction camera to slide at different positions of the slidingrail; and the computer is used for intertwining and displaying the red-blue image, receiving images shot by the correction camera and then conducting image analysis and comparison according to the images shot by the correction camera and the simulation intertwined image to determine the actual period offset, the actual slope offset and the center view point offset. According to the naked eye 3D display correction fixture, the actual period offset and the actual slope offset are determined by analyzing the shot images and the simulation image at at least two positions, automated correction ofa 3D module is achieved, the correction precision and efficiency are improved, and the labor cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of 3D display, and in particular to a naked-eye 3D display correction jig and correction method. Background technique [0002] With the development of 3D display technology, users can directly watch 3D display effects through the naked-eye 3D display module without wearing auxiliary equipment such as 3D glasses. The 3D display module includes optical components and display screens. When the optical components and display screens are installed and used after they leave the factory, their actual imaging parameters usually have certain errors from the design parameters. Before performing 3D imaging, 3D imaging is required. Calibration of module imaging parameters. [0003] In the prior art, the 3D display calibration is mostly done manually, that is, the parameters are continuously corrected in the form of trial and error, and the calibration value is obtained through manual judgment....
