Natural three-dimensional television system

Abstract

The invention discloses a natural three-dimensional television system, which adopts a multi-destination stereo camera to attain a colorful image of a scene, adopts an image correcting module to compensate brightness and colors, adopts a content producing module to extract three paths of code streams as a main camera colorful image, a main camera depth image and the shade information of an auxiliary camera; adopts a standard coder to process layered coding, and transmits the generated compressed stream to the standard coder via a channel, to be analyzed and decoded into three paths of code streams; adopts a viewpoint reconstruction module to reconstruct the three paths of code streams into a main camera viewpoint, an auxiliary camera viewpoint and a virtual viewpoint, to be synthesized by a display module into an image adaptive to a display device, to be displayed on the display device. The invention has the advantages that the invention is compatible with traditional 2D system, has many sideward viewpoints for reconstruction and can confirm low transmission bit rate.

Description

technical field The invention relates to a natural three-dimensional television system, specifically including a depth-based three-dimensional television encoding and decoding method and a multi-view reconstruction method. Background technique Since the invention of television in the 1940s, it has gone through three stages: black-and-white television, color television, and digital high-definition television under development. Television technology is gradually developing towards large screen, colorization, high-definition, and multimedia. And three-dimensional TV (3DTV) has a sense of depth and presence, and will enable the audience to obtain the maximum three-dimensional experience, so it will become another new development direction after digital high-definition television technology. The three-dimensional perception produced by human eyes is mainly based on two aspects: binocular parallax and motion parallax. Binocular parallax began with the work of Charles Wheatstone ...

AI Technical Summary

Problems solved by technology

This is a 3DTV solution compatible with traditional 2D TVs. Although this solution can theoretically reconstruct the image of any viewpoint, it will produce a larger hole when the distance is far away, and the visual effect is poor, so it is only suitable for a single person Observation from limited angles
