Problems solved by technology

However, due to the production error of the cylindrical lens grating, the installation error between the 2D display screen and the cylindrical lens grating, etc., there is an error between the factory parameters and the actual parameters, so it is necessary to re-measure the parameters of the cylindrical lens grating display
However, the existing measurement techniques (such as shearing interferometry, moiré fringe method, etc.) have low measurement accuracy, and need to be applied to optical instruments, and the cylindrical lens grating needs to be measured separately. extremely unfavorable

Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The existing lenticular grating display is to add a lenticular grating on the 2D display panel. The pixel light is refracted by the lenticular lens to project the parallax composite image to the left and right eyes of the human body, and the three-dimensional effect is obtained through the three-dimensional fusion of the human visual center. see figure 1, wherein, the human eye 101 is used to receive the formed parallax composite image; the cylindrical ...

Abstract

The invention discloses a grating parameter output method and device, applied to the technical field of accurate measurement of parameters of 3D displays. The method comprises the following steps: obtaining a preset grating pitch and an inclination angle of a cylindrical lens grating display, and determining a view point matrix composite graph; displaying the view point matrix composite graph on the cylindrical lens grating display to generate a parallax composite graph; adjusting the grating pitch and the inclination angle of the cylindrical lens grating display to generate a final parallax composite graph; and outputting numerical values of the grating pitch and the inclination angle of the cylindrical lens grating display corresponding to the final parallax composite graph. According to the invention, the accurate measurement of the grating pitch and the inclination angle of the cylindrical lens grating display is achieved, and the mounting error between the cylindrical lens grating and a 2D display is effectively avoided, thereby being more labor-saving and time-saving.

Description

technical field [0001] The invention relates to the technical field of 3D display parameter measurement, in particular to a method and device for grating parameter output. Background technique [0002] 3D display technology has gradually matured and entered the lives of the public, bringing people higher-quality video enjoyment. Cylindrical lens 3D display technology stands out in 3D display technology for its good 3D display effect and high brightness. [0003] The existing lenticular lens grating 3D display (hereinafter referred to as lenticular lenticular grating display) is mainly composed of a 2D display screen and a lenticular lenticular grating. However, due to the production error of the lenticular lens grating and the installation error between the 2D display and the lenticular lenticular grating at the factory, there is an error between the factory parameters and the actual parameters. Therefore, it is necessary to re-measure the parameters of the lenticular lenti...
