Problems solved by technology

[0005] 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 program 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 DLP Link 3D stereoscopic projection system composed of a single graphics card and its software correction and fusion processing method have not yet been developed. related reports

Abstract

The invention discloses a GPU-based single-graphics card three-channel stereo visual projection software calibration and fusion method, and belongs to the field of visual simulation technology. The method is based on a vertex shader and a pixel shader of a GPU to complete the segmentation of a stereo image in a frame buffer, left and right eye graph geometric correction and edge fusion, and finally, a complete frame buffer image is obtained by splicing processing. The method is suitable for single-graphics card multi-screen stereo image output, which combines the advantages of GPU programmable parallel processing so that the geometric correction and edge fusion operation for the rendering of the image are completed in the GPU, the processing speed of the geometric correction and edge fusion can be improved, and the impact of software correction and fusion on the visual rendering real-time performance is reduced.

Description

[0001] This application is a divisional application of a patent application with an application date of December 23, 2015, an application number of 201510980707.8, and an invention title of "A Single Graphics Card Three-Channel Stereoscopic Vision System Construction and Its Correction and Fusion Method". technical field [0002] 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 [0003] The large field of view dome stereo vision system ...
