Abstract

The invention discloses a 2D video three-dimensional method based on sample learning and depth image transmission. The problem that in an existing 2D video three-dimensional process, computation complexity is high, and applicability is poor is mainly solved. The method comprises the steps that (1) two frames of 2D video images are input; (2) the best depth values of pixel positions of the first frame of video image are obtained through the method based on sample learning; (3) the best depth values are subjected to postprocessing; (4) the depth values of pixel positions of the input second frame of video image are obtained through a depth transmission technology; and (5) through a drawing technology based on depth images, input video images and the obtained depth values of the pixel positions are combined, and left-right-format 3D video is formed. According to the method, computation complexity is low, high-quality depth images which are obvious in moving foreground, clear in edge and natural in structure can be obtained, so that 3D video which is good in stereoscopic vision effect is formed, and the method can be widely used in video processing relevant to 3D televisions.

Description

technical field

[0001] The invention belongs to the technical field of video processing, and relates to a video stereoscopic method, which can be used to convert 2D video into 3D stereoscopic video. Background technique

[0002] With the rapid development of 3D TV technology, people can watch more three-dimensional and realistic video programs through 3D TV, but the development of 3D TV is greatly limited due to the lack of 3D resources. In the prior art, 3D content is obtained by shooting with a 3D stereo camera, but the cost of this method is too expensive and the professional requirements are relatively high. Therefore, someone proposes to convert the existing 2D resources into a 3D stereoscopic format to make up for the shortage of 3D resources.

[0003] Converting 2D resources into a 3D stereoscopic format is to stereotype 2D video, that is, to generate a 3D stereoscopic video by estimating a depth image from a video sequence and using a depth image rendering technolog...
