All-purpose stereoscopic picture synthesizing process based on pole mirror grating LCD freedom stereo display equipment

Abstract

The invention discloses a universal three-dimensional picture synthesis method based on lenticular grating LCD (liquid crystal display) free three-dimensional display device, comprising the following steps: 1) measuring the actual lines LPI value and actual elevation angle Alpha value of the lenticular grating; 2) carrying out sampling on N viewport pictures according to the required viewport number N and resolution factor H*V of synthesizing three-dimensional pictures, the vertical resolution factor of each viewport image being sampled to be V / v, and the horizontal resolution factor being sampled to be H / h, wherein, N is more than or equal to 2, v*h is equal to N, and v is an integral value mostly close to N; 3) filling the RGB (red, green, blue) components of N sampled viewport pictures in the RGB components of the three-dimensional pictures according to the actual lines LPI value, the actual elevation angle Alpha value and the dot pitch DOT of an LCD display so as to obtain the required three-dimensional pictures. The universal three-dimensional picture synthesis method is applied to lenticular grating with random lines LPI value and random elevation angle Alpha value, and can quickly and accurately synthesize three-dimensional pictures with random viewport numbers and random resolution factor.

Description

technical field [0001] The invention relates to a general stereoscopic image synthesis method based on a lenticular lens grating LCD autostereoscopic display device. Background technique [0002] With the continuous development of display technology, people have developed a variety of free stereoscopic display technologies that can directly watch stereoscopic images with naked eyes without the aid of stereoscopic glasses and other auxiliary visual aids, mainly including lenticular grating stereoscopic display, narrow Slit grating stereoscopic display, holographic stereoscopic display and volumetric 3D stereoscopic display, etc. Among the numerous autostereoscopic display technologies, the autostereoscopic display technology based on lenticular lens has become the more common autostereoscopic display technology because the lenticular grating is easy to process and the stereoscopic effect is outstanding. [0003] The three-dimensional grating is generally attached to the outs...

Problems solved by technology

[0004] Based on the consideration of implementation complexity and versatility, the stereoscopic image synthesis method matched with the existing lenticular-based LCD autostereoscopic display device is generally only applicable to the lenticular grating with a specific line number LPI value and an inclination angle α value, and Generally, only stereoscopic images with a fixed number of viewpoints and a fixed resolution can be synthesized. Such a stereoscopic image synthesis method obviously lacks universality, which greatly limits the application field of autostereoscopic display devices based on lenticular gratings.
