Abstract

The invention provides a depth-map gaining method of plane videos. The depth-map gaining method comprises the following steps of: detecting and extracting a foreground moving object in an original plane video, calculating a blocking relation of the foreground moving object and obtaining a mask image of the foreground moving object; carrying out background reconstruction on the original plane video according to the mask image of the foreground moving object so as to obtain a background video sequence with removal of the foreground moving object; solving a background depth-map sequence for the background video sequence; solving an initial depth-map sequence for the original plane video; and obtaining a depth-map sequence of the original plane video according to initial depth information of the foreground moving object in the initial depth-map sequence and geometric information of the foreground moving object in the background depth-map sequence. According to the method provided by the embodiment of the invention, the depth map of each frame in the plane video can be accurately gained; the gained depth map is clear in edge, explicit in depth hierarchy, good in smooth performance and high in time-domain stability.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for obtaining a depth map of a plane video based on background reconstruction and motion detection. Background technique [0002] In the stereoscopic video processing technology, the generation of the depth map of the planar video refers to obtaining the sequence of depth maps identifying the stereoscopic information of the scene through the planar video. [0003] At present, the commonly used depth map generation method mainly uses the geometric information of the planar video, camera parameters, and the color features of the objects in the planar video for global calculation. In addition, the depth map of the non-key frame can be calculated through the key frame image and the corresponding depth map, and the calculation method mainly includes methods such as depth diffusion or contour tracking. This method has a better effect in scenes with small changes in k...
