MP3-based point cloud compression

초록

Geometry-based Point Cloud Compression (G-PCC) and Video-based Point Cloud Compression (V-PCC), which are standards developed by MPEG, can be used in compressing the point cloud data. However, these standards do not yet support encoding and decoding in many devices. In order to utilize the point cloud data in many devices, we conducted a study on compression and restoration of the point cloud using legacy codec. Legacy codec has already been used and verified in many devices. And if it is possible to compress and restore point cloud data by utilizing legacy codec, point cloud data can be used on many devices. In this paper, we proposed a method to design point cloud compression based on MP3. We chose MP3 for its proven, popular use, and ubiquitous support of encoder and decoder. We compared proposed method with the G-PCC reference software for performance evaluation.
