Optical grating prism three-dimensional display rendering method based on optical field acquisition

Abstract

The invention relates to an optical grating prism three-dimensional display rendering method based on optical field acquisition. The method comprises steps of uniformly presetting multiple vision points on an LCD panel, and rendering initial synthesis index plans of the views respectively by use of a multi-view rendering method put forward by the Philip research laboratory; moving a camera to each view to successively display each initial synthesis index plan and carrying out optical field acquisition of images to merge the optical fields into a real optical field; optimizing the real optical field to allow the real optical field to be close to an ideal optical field maximally; and according to a mapping rule from the initial synthesis index plans displayed on the LCD panel to an observation plane, reversely searching to obtain a target synthesis index plan. According to the invention, for different specifications of three-dimensional displays, the target synthesis index plan is obtained through the above calibration method; a three-dimensional image to be displayed on the display device are rendered by use of corresponding target synthesis index plan, so crosstalk can be effectively reduced; and three-dimensional displaying of various views can be rendered without additional hardware devices.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display optimization of images, in particular to a grating prism three-dimensional display rendering method based on light field collection. Background technique [0002] Three-dimensional display technology has broad prospects because it is closer to the actual perception of human beings. The research purpose of the light field 3D display system is to explore how to restore the light field, that is, how to control the outgoing direction and angle of each light ray. [0003] The grating prism display device includes an LCD display (Liquid Crystal Display, liquid crystal display), transparent plexiglass and a lenticular grating plate. By installing transparent organic glass between the LCD display screen and the lenticular lens grating plate, the distance between the two is the focal length of the lenticular lens grating unit. The pixels of N viewpoints will be enlarged and projected to...

AI Technical Summary

Problems solved by technology

[0004] 1. The grating prism display still has the problem of crosstalk between adjacent viewpoints;

[0005] 2. The number of viewpoints displayed by the grating prism is small, which affects the final effect of 3D display

Although these methods solve the problem of viewpoint crosstalk to a certain extent, the overhead of hardware cost is large, or the amount of calculation is large
