Construction method and correction and fusion method for single-video-card three-channel stereo visual system

Abstract

The invention discloses a construction scheme for a stereo visual projection system performing single-video-card three-channel image output and a stereo image software correction and fusion method based on an GPU (graphics processing unit), belongs to the technical field of visual simulation, overcomes the defects of larger amount, high cost, complicated scheme and the like of passive dual-machine stereo projection hardware equipment and is a multi-channel stereo visual implementation scheme with economy, feasibility and simple structure. The stereo visual system adopts a single video card to output three channels of stereo visual images to three stereo projectors and comprises a visual pattern generation system, a protection display system and a video distribution and monitoring system, segmentation of stereo images in a frame buffer as well as geometric correction and edge blending of left and right eye subgraphs is finished on the basis of a vertex shader and a pixel shader of the GPU, and complete frame buffer images are formed through splicing processing. The methods are mainly applied to visual system simulation for adopting the single video card to output three-channel left-right format or up-down format stereo images to the projectors, so that generation and projection of three-channel stereo images are realized.

Description

technical field [0001] The invention belongs to the technical field of visual simulation, and specifically refers to a realization scheme of a stereoscopic visual projection system for single graphics card three-channel image output and a GPU-based stereoscopic image software correction and fusion method. The present invention is mainly used for the simulation of the visual system in which three-way left-right format or up-and-down format stereoscopic images of a single graphics card are output to a projector, so as to achieve the generation and projection of three-channel stereoscopic images. Background technique [0002] The large field of view dome stereo vision system can provide viewers with the realistic sense of scenery, three-dimensional sense, the feeling of infinity in nature and the large field of view environment that meets the vision of human eyes, so that observers can obtain more comprehensive information and achieve The feeling of being there. The vision sys...

Problems solved by technology

[0004] Although there have been some precedents for the application of multi-channel stereoscopic display technology at home and abroad, most of them use passive stereoscopic projection with a pair of projectors, or active stereoscopic projection with plate screens. The scheme is complex and other disadvantages, and there is little research on the software correction and fusion of multi-channel stereo projection, especially the multi-channel active DLPLink3D stereoscopic projection system composed of a single graphics card and its software correction and fusion processing method have not yet been related. to report
