Abstract

The invention discloses a panorama gap real-time stitching method and system realized based on GPU, and the method comprises the steps: obtaining a gap needing to be stitched based on the position and direction of a camera, a panorama three-dimensional box, and the position and direction of the panorama; based on pixels near the gap needing to be sewn, sewing the gap needing to be sewn, and eliminating the gap; the research and development process is shortened, and the research and development efficiency is improved; flaws caused by errors, especially scenes of frequent change and large-scale resource application, are avoided; and the panoramic scene is more vivid and finer.

Description

technical field [0001] The invention relates to the technical field of VR, in particular to a GPU-based real-time stitching method and system for panorama gaps. Background technique [0002] The current immersive scenes rendered by VR devices include real-time rendering of 3D scenes and virtual scenes of panoramas. The former has higher requirements on hardware, while the latter has a strong sense of reality and low hardware requirements, so it has a wider range of applications, although its real-time performance is not high. When the panorama is rendered with a stereo box, defects such as gaps and light leakage may occur at the stitching due to texture setting problems. [0003] At present, the mainstream processing technology to solve the defects is to set the texture sampling algorithm to statically avoid these defects. First, the texture sampling design is performed, and then the normal rendering pipeline is performed. Contents of the invention [0004] The purpose of...
