Research and Standardization Trends in Compression and Transmission Technologies for 3D Point Cloud

摘要

The demand for 3D spatial information is rapidly increasing across a wide range of industrial fields. For instance, 3D point cloud data is being actively adopted in sectors such as construction, civil engineering, and disaster prevention to enhance work efficiency and safety. However, 3D point cloud data typically involves extremely large data volumes, which presents a significant challenge; as a result, rapid sharing and utilization over public networks has yet to be fully realized. To address these issues, we are engaged in research and development of compression and transmission technologies for 3D point clouds, as well as contributing to international standardization. In this talk, as part of our initiatives aimed at industrial applications, we will present the latest trends in the international standardization of 3D point cloud compression technologies, such as Geometry-based Point Cloud Compression, and introduce case studies from demonstration experiments utilizing these technologies.
