ISO/IEC 23488:2022该文档指定了一种基于图像的表示模型，该模型使用一组图像和可选的底层3D模型来表示目标对象/环境，用于在任意视点处准确和高效地表示对象/环境。它适用于广泛的图形、虚拟现实和混合现实应用，这些应用需要用各种对象和环境来表示场景的方法。本文件:-定义用于基于图像的表示和3D重建技术的术语；-指定用于基于图像的表示的所需元素；-指定基于基于图像的表示在虚拟空间中表示真实世界的方法；-指定如何将可见图像块与底层3D模型集成以从任意视点更准确和丰富的对象/环境表示；-指定所提出的模型如何允许多对象表示；-提供了所提出的表示模型的基于XML的规范和实际实现示例（见附录A）。

ISO/IEC 23488:2022 This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments.
This document:
- defines terms for image-based representation and 3D reconstruction techniques;
- specifies the required elements for image-based representation;
- specifies a method of representing the real world in the virtual space based on image-based representation;
- specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints;
- specifies how the proposed model allows multi-object representation;
- provides an XML based specification of the proposed representation model and an actual implementation example (see Annex A).
