Abstract

The invention provides a binocular video depth map calculating method. The method includes the following steps of carrying out edge detection on two pictures, carrying out picture segmentation on the two pictures, carrying out classification on detected edges by using of picture segmentation results, and carrying out depth calculation through improvement of a BP algorithm. According to the method, edge detection results are obtained through improving of a canny operator, then relation of the edges and the segmentation results is analyzed, the BP algorithm is improved, single transmission is carried out in different areas, and a message transmission mechanism is changed; single processing is carried out on a shielded part so as to enable the shielded part not to influence transmission of correct messages, the iteration speed is increased, and precision is improved.

Description

technical field

[0001] The invention relates to the technical field of computer multimedia, in particular to a method for obtaining a binocular video depth map. Background technique

[0002] Stereoscopic video is a new type of video technology that can make people feel three-dimensional. It can make users have a clear sense of reality and presence. It is the development direction of future multimedia technology. The currently commonly used stereoscopic video architecture is as follows: transmit two pieces of video at the same time, one of which is a planar video sequence to be converted, and the other is a corresponding depth map sequence, which contains the depth information of each pixel in each frame. DIBR (Depth-Image-Based Rendering, based on depth map rendering) technology can obtain virtual perspectives of real-world scenes in one or more directions, and finally synthesize stereoscopic videos. In the stereoscopic video architecture using DIBR technology, the most imp...
