Abstract

The invention relates to a shielding scene drawing method and device and a storage medium, and belongs to the technical field of light field drawing. The method comprises the following steps: sending a shooting signal carrying an initial sampling rate to a pre-arranged camera array, and when shooting is completed, obtaining a shot multi-view image from the camera array; performing mathematical quantization on the scene surface in the multi-view image to obtain a surface shielding model for describing a shielding scene; converting the surface shielding model into a light field function of a shielding scene under a two-dimensional plane; performing spectral analysis on the light field function to obtain a minimum sampling rate; a new shooting signal is sent to the camera array, the new shooting signal carries the sampling period, the new shooting signal is used for the camera array to shoot again according to the minimum sampling rate, and a new multi-view image is obtained. According to the method, the problem of light field drawing with a shielding phenomenon in a scene can be solved, and a high-quality new viewpoint drawing effect can still be realized while viewpoints are reduced.

Description

technical field [0001] The present invention mainly relates to the technical field of light field rendering, and in particular relates to a rendering method, device and storage medium for an occlusion scene. Background technique [0002] In the information age, 3D video technology realizes immersive visual experience. These visual experiences are mainly realized through IBR technology. The light field rendering technology is one of the commonly used methods of IBR technology. First, a set of multi-viewpoint images of the scene is captured through the camera array, and then any new viewpoint of the scene can be drawn by a simple interpolation method. The biggest advantage of this technology is that it does not need to rely on the precise geometric information of the scene surface, or only relies on a small amount of scene surface geometric information in the process of drawing new viewpoints. However, the biggest disadvantage of this technique is that it needs to acquire a ...
