ISO/IEC 23090-9:2023

Overview

ISO/IEC 23090-9:2023 is an international standard developed by ISO and IEC for the coded representation of immersive media, specifically focusing on geometry-based point cloud compression. This standard outlines the requirements and processes for efficiently compressing 3D point clouds, which are fundamental for various immersive experiences and next-generation media applications where visualization and manipulation of complex 3D scenes are needed. With the increasing adoption of augmented reality (AR), virtual reality (VR), and 3D video, this standard ensures interoperability and high performance for advanced immersive media content.

Key Topics

• Point Cloud Compression: Defines methods and syntax for geometry-based compression of 3D point clouds, optimizing storage and transmission without significant loss in quality.
• Coded Representation: Specifies how 3D geometry and attributes are encoded to maximize compatibility and minimize bandwidth requirements.
• Attributes Handling: Details on managing attributes such as color, opacity, reflectance, normal vector, material identifier, and user-defined properties associated with each point.
• Decoding Process: Defines the systematic approach for decoding compressed point cloud data back to its usable format in output applications.
• Syntax and Semantics: Establishes the framework for representing compressed point cloud data in a consistent and interoperable way.
• Profiles and Levels: Introduces profiles and levels to ensure scalability and to address the needs of different applications and device capabilities.
• Error Resilience and Scalability: Mechanisms for partial decoding, spatial scalability, and error handling are included to support various use cases and network environments.

Applications

Geometry-based point cloud compression under ISO/IEC 23090-9:2023 is crucial in the following sectors:

• Immersive Media Production: Powers next-generation content in AR/VR by enabling realistic 3D scene construction in entertainment, gaming, and virtual events.
• 3D Communication and Telepresence: Facilitates efficient transmission of real-time 3D scenes for collaboration, remote support, or virtual meetings.
• Digital Twins and Industrial Applications: Supports industries like construction, manufacturing, and asset management by compressing detailed 3D scans for simulation, inspection, and monitoring.
• Smart Cities and Mapping: Optimizes storage and network usage for large-scale 3D models captured from urban mapping or autonomous vehicle sensors.
• Medical Imaging: Enhances visualization and sharing of high-resolution 3D scans in healthcare diagnostics and telemedicine.

By following the ISO/IEC 23090-9:2023 framework, organizations and developers ensure high efficiency, reduced latency, and compatibility across platforms and devices.
