Embodiment Construction

[0030] In the embodiment of the present invention, during the encoding process of video images of multiple views, the frame number and viewpoint identifier of the reference frame information are written into the code stream as auxiliary enhancement information and sent to the decoding end. In this way, in the process of decoding the video image information of multiple views, the frame number and viewpoint identifier of the reference frame information can be obtained by decoding from the received multi-viewpoint video coded stream. After decoding and obtaining the frame number and viewpoint identifier of the reference frame information at the decoding end, the currently used reference frame information can be determined according to the frame number and viewpoint identifier of the reference frame information; further, the reference frame information can be determined according to the reference frame information Frame information restores the current frame where an error occurred...

Abstract

The invention relates to a multi-viewpoint encoding-decoding method and a device thereof. The method mainly comprises the following steps that: in the process of encoding a multi-viewpoint video image, a frame number and a viewpoint mark of reference frame information are written into a code stream and sent to a decoding end, so as to ensure that the decoding end can decode the acquired frame number and the viewpoint mark of the reference frame information, and can determine the reference frame information adopted currently according to the frame number and the viewpoint mark of the reference frame information; then recovery processing can be further carried out to a current frame having an error according to the reference frame information. Therefore, the realization of the embodiment of the invention ensures that inter-frame information which can be effectively utilized in error code recovering process can be determined at the decoding end according to the viewpoint mark information, so as to improve the multi-viewpoint video encoding-decoding performance.

Description

technical field [0001] The present invention relates to codec technology, in particular to a multi-view codec technology. Background technique [0002] With the rapid development of multimedia communication technology, people are no longer satisfied with the traditional fixed-viewpoint vision and 2D (two-dimensional) plane vision. In many application fields such as entertainment, education, sightseeing and surgery, there have been multi-view video, free The demand for point-of-view video and 3D (three-dimensional) video. [0003] In order to meet the corresponding requirements, multiple cameras can be used to obtain a group of video signals of the same scene at different spatial positions and different angles at the same time. This group of video signals is called multi-viewpoint video. After that, the obtained group of Video signals are compressed, encoded and transmitted, and the process of compressing and encoding the group of video signals is called multi-view video cod...
