本文件定义了混合和增强现实的范围和关键概念、相关术语及其定义，以及一个通用的系统体系结构，它们共同作为混合和增强现实（MAR）应用、组件、系统、服务和规范的参考模型。该体系结构参考模型建立了一套所需的子模块及其最低功能、相关信息内容以及由符合要求的MAR系统提供和/或支持的信息模型。 参考模型旨在供MAR应用程序、组件、系统、服务或规范的当前和未来开发人员使用，以描述、比较、对比和传达其架构设计和实施。MAR参考模型旨在应用于MAR系统，与特定算法、实施方法、计算平台、显示系统和所用传感器或设备无关。 本文件未规定特定MAR应用程序、组件、系统、服务或规范的设计、开发或实施方式。它没有规定这些设计和概念与编程语言的绑定，也没有规定通过任何编码技术或交换格式对MAR信息进行编码。本文档包含与参考模型有关的代表性系统类和用例列表。

This document defines the scope and key concepts of mixed and augmented reality, the relevant terms and their definitions and a generalized system architecture that together serve as a reference model for mixed and augmented reality (MAR) applications, components, systems, services and specifications. This architectural reference model establishes the set of required sub-modules and their minimum functions, the associated information content and the information models to be provided and/or supported by a compliant MAR system. The reference model is intended for use by current and future developers of MAR applications, components, systems, services or specifications to describe, compare, contrast and communicate their architectural design and implementation. The MAR reference model is designed to apply to MAR systems independent of specific algorithms, implementation methods, computational platforms, display systems and sensors or devices used. This document does not specify how a particular MAR application, component, system, service or specification is designed, developed or implemented. It does not specify the bindings of those designs and concepts to programming languages or the encoding of MAR information through any coding technique or interchange format. This document contains a list of representative system classes and use cases with respect to the reference model.
