信息技术 - 计算机图形、图像处理和环境数据表示 - 混合和增强现实内容的信息模型 - 核心对象和属性

[中文适用范围]： 本文档指定了用于表示混合和增强现实（MAR）场景/内容描述的信息模型，即用于以下方面信息构造：a）表示虚拟现实场景图和结构，以便可以表示全面的混合和增强现实内容；b）表示混合和增强现实场景中用于增强的物理对象；c）将物理对象表示为混合和增强现实场景中其他（虚拟或物理）对象的增强；d）提供将上述物理对象与混合和增强现实场景中相应的目标对象（虚拟或物理）进行空间关联的方法；e）提供支持动态 MAR 场景描述的其他必要功能和抽象，例如事件/数据映射和动态增强行为；f）描述这些构造与 MAR 系统之间的关联，MAR 系统负责获取和解释该信息模型并通过 MAR 显示设备进行渲染/呈现。 [外文原描述]： This document specifies the information model for representing the mixed and augmented reality (MAR) scene/contents description, namely, information constructs for: a) representing the virtual reality scene graph and structure such that a comprehensive range of mixed and augmented reality contents can also be represented; b) representing physical objects in the mixed and augmented reality scene targeted for augmentation; c) representing physical objects as augmentation to other (virtual or physical) objects in the mixed and augmented reality scene; d) providing ways to spatially associate aforementioned physical objects with the corresponding target objects (virtual or physical) in the mixed and augmented reality scene; e) providing other necessary functionalities and abstractions that will support the dynamic MAR scene description such as event/data mapping, and dynamic augmentation behaviours; f) describing the association between these constructs and the MAR system which is responsible for taking and interpreting this information model and rendering/presenting it out through the MAR display device.
