Information technology - Augmented reality software component interface

1 Scope

GB/T 44247-2024 specifies the software component interface for augmented reality in the Chinese standards system. An AR application sits on a stack that has to do several hard things at once, track the camera pose, understand the surfaces and the lighting of the room, recognise images and objects, detect collisions between virtual and real geometry, and it depends entirely on the platform underneath it; an application written for one vendor's runtime does not run on another's. This standard defines a common interface so that it can. It sets the classification of the interfaces and the call flow, then specifies them class by class: the session class, with the session, configuration and camera interfaces; the frame data class, with the frame image, image, image database and sparse spatial map interfaces; the trackable object class, including face augmentation; the collision detection class; and the environment understanding class. Two normative annexes define the special and enumerated data types. For an AR platform or application developer working to Chinese requirements, this is the interface.

This document specifies the software component interfaces for augmented reality, including session interfaces, frame data interfaces, trackable object interfaces, Collision detection class interface and environment understanding class interface. This document applies to the representation and application of augmented reality software component interfaces.

The following terms and definitions apply to this document.

3.1 Component The software system has relatively independent functions, can be clearly identified, the interface is specified by the contract, has obvious dependencies on the context, and can be independently deployed. Deployable assembler software entity. [Source: GB/T 36455-2018, 3.1]

3.2 componentinterface The only channel for software components to communicate and interact with the outside world.

3.3 Augmented reality The environment that uses computer-based modern high-tech means to generate additional information to enhance the real world perceived by users. The generated additional information is superimposed on the real scene in a fusion manner. [Source: GB/T 38247-2019, 2.1.2]

3.4 augmentedrealitysession A message mechanism for managing the operation of various parts in augmented reality.
