      Abstract: Three-dimensional high efficiency video coding (3D-HEVC) is the latest 3D video coding standard launched by Joint Collaborative Team on 3D Video Coding Extension Development (JCT-3V). The research of 3D-HEVC-based video coding technology promotes its application and becomes a hot research topic of current 3D video coding technology. In this paper, a three-dimensional video coding scheme based on 3D-HEVC and especially three-dimensional texture and depth coding based on 3D-HEVC were reviewed. First, three-dimensional texture coding was analyzed by utilizing texture characteristics of video sequences, and then their problems were analyzed. Second, the three-dimensional depth coding based on texture characteristics and region were discussed and analyzed. Finally, combined with the latest research results, the development of three-dimensional video coding technology was prospected and new research topics were put forward.
