Abstract:

Information compression is one of the most important technologies of information transmission. With the development of 3D display and 3D video technology, video transmission will not only be limited in 2D video in the future. However, the large amounts of data of the 3D video have hindered its transmission. Therefore, 3D video compression with a high compression ratio and high compression efficiency must be designed, which can not only solve the transmission of 3D video but is also conducive to promoting the 3D video and 3D display for further development. This paper describes the progress in 3D video compression, and gives some advices for further study, based on summarizing the technologies of video compression.
