摘要:点云编码是支撑点云广泛应用的关键技术之一,是近期技术研究和标准化领域的热点。对点云几何信息和属性信息编码技术演进进行了回顾,并比较了针对稠密点云和稀疏点云的几种典型编码方法的编码效率。未来点云编码研究将集中在利用帧间预测去除动态点云、不同帧之间的相关性、端到端点云编码、任务驱动的点云编码等方面。

Abstract: 3D point cloud compression is one of the key technologies supporting the widespread use of point clouds. Recently, it is one of the focuses for both research and standardization groups. The latest advance of the compression technologies for both the 3D point cloud geometry and attribute information is reviewed. Compression efficiencies of several typical compression technologies for both the 3D dense and sparse point clouds are compared. In the future, more studies will focus on inter-frame prediction to exploit the correlations between different frames, end-to-end point cloud compression, and task-driven point cloud compression. 
Keywords: 3D point cloud compression; geometry information coding; attribute information coding
