Problems solved by technology

[0006] The disadvantage of using a single reference image to project a virtual viewpoint is that when the virtual camera is too far away from the known camera, the holes caused by a large number of occlusions in the virtual screen are difficult to be effect

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Aiming at the problems of artifacts and holes in virtual view synthesis, a new method of view rendering based on depth image is proposed. This method first uses the synchronous generation mechanism of the viewpoint to obtain the image and depth information of the virtual viewpoint, and erases the background artifacts according to the depth information; secondly, further eliminates the hole and foreground edge distortion in the viewpoint image through the dept...

Abstract

The invention discloses a method for drawing a depth image on the basis of a 3D video and a free-viewpoint television. The method for drawing the depth image on the basis of the 3D video and the free-viewpoint television includes the following steps of synchronizing a production mechanism, erasing background artifacts, combining viewpoints, and conducting hole filling and boundary treatment on the basis of the depth. According to the method for drawing the depth image on the basis of the 3D video and the free-viewpoint television, through a hole filling and boundary treatment method based on the depth, the problems of the hole filling and distortion of the foreground boundary are solved.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method for rendering depth images based on 3D video and free-viewpoint television. Background technique [0002] With the continuous development of digital multimedia technology, people continue to put forward higher requirements for video interactivity and sensory experience. Traditional two-dimensional video is viewed from a fixed plane perspective, and people can only passively accept visual information. The key to the entire video technology Concentrating on the codec method, this traditional 20 video has become more and more mature with the introduction of the H.264 codec standard. On this basis, various digital high-definition televisions (HOTV) have entered people's daily life one after another. , but in addition to obtaining a higher video resolution, the user cannot get a further video experience. The progress of the times has made this traditional method o...
