Description

technical field

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

[0002] Various existing video media generally exist in the form of a plane, but the above-mentioned video media has lost the depth information of a specific scene while acquiring it.

[0003] Stereoscopic video technology, as the development direction of future multimedia technology, is a new type of video technology that can provide stereoscopic effect. Compared with single-channel video, stereoscopic video generally has two video channels, and the amount of data is much larger than single-channel video, so efficient compression of stereoscopic video is particularly important. Specifically, the stereoscopic video not only contains the surface information about the scene of the traditional two-dimensional video, but also contains the three-dimensional information related to the specific position of the...
