Abstract

The invention provides a virtual view rendering method which comprises the following steps of: (S1) according to a first view and a second view at a first reference viewpoint and a second reference viewpoint, respectively calculating a first disparity map of the first view relative to the second view and a second disparity map of the second view relative to the first view; (S2) according to the first view and the first disparity map as well as the second view and the second disparity map, rendering a virtual view, and respectively establishing a first index map and a second index map of the virtual view, corresponding to the first disparity and the second disparity; (S3) detecting a hole with the area exceeding a first threshold in the virtual view, determining the corresponding regions of the hole in the first view and the second view according to the first index map and the second map, and taking values in the corresponding regions to fill the hole; and (S4) filling the rest holes in the virtual view. Image processing traces are not obvious by using the method, and the reality of the virtual view is strong.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a virtual view rendering method. Background technique [0002] Stereoscopic display technology has good application prospects in television, film, medical treatment, education and other aspects. Currently, there are two main types of stereoscopic display technologies: display technology based on binocular stereoscopic imaging and naked-eye multi-viewpoint stereoscopic display technology. Among them, the naked-eye multi-viewpoint stereoscopic display technology does not need to wear auxiliary viewing equipment, which is more in line with people's viewing needs. [0003] The naked-eye multi-viewpoint display technology requires multiple images from different viewpoints as film sources. The acquisition methods of multi-viewpoint images include multi-viewpoint acquisition, 3D modeling, and virtual view rendering. The virtual view rendering method based on depth map or disp...
