MPEG Geometry-Based Point Cloud Compression (G-PCC) Standard

Advances in 3D representation technology have promoted the development of digital museums, automated driving, and other virtual/augmented reality applications. The 3D point cloud is widely used in these emerging applications, thanks to its efficient and concise simulation of 3D objects and scenes, and it provides free views to users via its geometry (the coordinate in 3D space) and attribute (e.g., color, reflectance). Nevertheless, the vast amount of data carried by point clouds limits the deployment of the related applications in terms of efficient communication and storage. To tackle this problem, the Moving Picture Experts Group (MPEG) has launched standardization for directly coding point clouds in 3D space, i.e., geometry-based point cloud compression (G-PCC) codec.
