Abstract

The invention discloses a binocular video depth map obtaining method based on image segmentation and motion estimation. The method includes the following steps: respectively performing single-frame image segmentation for two images; performing depth calculating by aid of the stereo matching algorithm based on image segmentation; and rectifying depth extracting results by aid of motion estimation. A depth map extracted in the binocular video depth map obtaining method based on image segmentation and motion estimation is accurate in edges, an ideal effect can also be obtained on shielded portions, accuracy and timeliness are both considered, and the distance relation between scene objects is truly reflected.

Description

technical field

[0001] The invention relates to the field of computer multimedia technology, in particular to a method for obtaining a binocular video depth map based on image segmentation and motion estimation. Background technique

[0002] Stereoscopic video is a new type of video technology that can make people feel three-dimensional. It can make people see almost exactly the same scene as the real world through video, and produce a sense of reality and presence. Therefore, it will definitely become the development direction of future multimedia technology. . At present, the commonly used stereoscopic video architecture is as follows: two videos are transmitted 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, Through DIBR (Depth Image Based Rendering, based on depth map rendering) technology, obtain the virtual perspective of th...
