Abstract

The invention discloses a method and a system for acquiring a depth map of a binocular stereo video sequence. The method comprises the following steps: performing clustering on a first image in two images, adopting a region growing manner to transform all clusters to connected regions, and recording average five-dimension coordinates of all regions and adjacent information between two regions; receiving manual signs for marking foreground and background of the first image input by an operator, and calculating connection weight and sign weight of the regions; taking the connection weight and sign weight of the regions as input, and transferring the Graphcut algorithm to partition the foreground and the background of the first image; and taking the second image of the two images as a reference image, according to the partition result, calculating a disparity map of the foreground based on the partial self-adaption weight stereo matching algorithm, calculating a disparity map of the background based on the Rank transformation stereo matching algorithm, and then transforming the disparity maps into depth maps. The system is a system executing the method. The method and the system have the benefits of correct result and low complexity.

Description

technical field

[0001] The invention belongs to the field of computer image processing, in particular to a method and system for acquiring a depth map of a binocular stereoscopic video sequence. Background technique

[0002] With the rapid development of the current society, the demand for cultural entertainment appreciation is also increasing. The requirements for watching TV and movies are not only high-definition color, but also more realistic three-dimensional effects for movie viewers. The research and application of stereoscopic video has become a current hot issue. Stereoscopic video-related technical issues are also considered urgent issues.

[0003] Stereoscopic video is divided into traditional binocular stereoscopic video and multi-viewpoint video. Binocular stereoscopic video is composed of two video sequences. The point of view is single, which is far from the three-dimensional experience in real life. The multi-viewpoint video can adapt to the needs of naked-...
