Abstract

The present invention relates to a WebGL-based image projection fusion method, which includes obtaining a depth map obtained by rendering a loaded scene with a projection camera; using the depth map to draw and project all objects in the scene that need to be projected . The present invention realizes projecting projected images such as videos and pictures onto corresponding object surfaces in a virtual 3D scene, renders correct results, improves rendering efficiency, and improves the quality of obtained projected images. This rendering method can be widely used in visual field analysis, monitoring 3D visualization and other fields. The invention also relates to a WebGL-based image projection fusion device, storage medium and equipment.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a WebGL-based image projection fusion method, device, storage medium and equipment. Background technique [0002] Currently, when obtaining the projected image in the scene, it is usually necessary to render each frame repeatedly, resulting in extremely low rendering efficiency. In addition, the projection content area and the non-content area in the finally obtained projection image have a clear boundary, and the image quality is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a WebGL-based image projection fusion method, device, storage medium and equipment for the deficiencies of the prior art. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] A method for image projection fusion based on WebGL, said ...
