Carriage of Geometry-based Point Cloud Data progresses to Committee Draft
At its 131st meeting, WG11 (MPEG) has promoted the carriage of Geometry-based point cloud data (ISO/IEC 23090-18) to the Committee Draft stage, the first milestone of ISO standard development process. This standard is the second standard introducing the support of volumetric media in the industry-famous ISO base media file format (ISOBMFF) family of standards after the standard on the carriage of video-based point cloud data (ISO/IEC 23090-10). This standard (i.e., ISO/IEC 23090-18) supports the carriage of point cloud data within multiple file format tracks in order to support individual access of each attributes comprising a single point cloud. Additionally, it also allows the carriage of point cloud data in one file format track for simple applications. Understanding the point cloud data could cover large geographical area and the size of the data could be massive in some application the standard support 3D region-based partial access of the data stored in the file so that the application can efficiently access the portion of data required to be processed. It is currently expected that the standard will reach its final milestone by mid-2021.
