Abstract

The invention discloses a virtual viewpoint synthesis method and a virtual viewpoint synthesis device and relates to the technical field of electronic information with an aim to solve problems about ambiguity, image overlapping, appearance of artificial edges and the like of object shade relations in virtual viewpoint synthesis. The virtual viewpoint synthesis method includes: respectively acquiring image information acquired through at least two video image acquisition devices, wherein the video image acquisition devices are different in shooting angle; according to depth image information in the image information, separating background images and foreground images from images acquired through the video image acquisition devices; performing three-dimensional transformation and image synthesis on a targeted viewpoint direction of the background images and the foreground images to form a virtual viewpoint image corresponding to the target viewpoint direction.

Description

technical field [0001] The invention relates to the field of electronic information technology, in particular to a method and device for synthesizing virtual viewpoints. Background technique [0002] With the rapid improvement of Internet technology and the rapid development of the electronic communication industry, digital image technology is a very powerful tool for the generation, dissemination and expression of video content, especially the stereoscopic display technology can express the depth and layering of the scene more realistically. Free-viewpoint stereoscopic television (FTV "Free-viewpoint TV") is one of them. The feature of free-viewpoint stereoscopic TV is that observers can watch images from different perspectives of scenes in the TV image in different directions of the TV, so it can provide more information than traditional media, so that users can dynamically see scenes from any perspective in real time. E.g, figure 1 The football field and video image acq...
