Introduction

OpenXRLab XRAPI is an open-source implementation of the Google ARCore SDK and the "Information technology - Application interfaces of augmented reality system for mobile devices"(《信息技术 移动设备增强现实系统应用接口》). This standard specifies the data types and interface definitions for mobile device augmented reality system application development, and be used to guide the design, development and implementation of mobile device augmented reality systems. XIAPI is part of the OpenXRLab project. We hope that XIAPI can connect industry and academia, give full play to their respective advantages, and form a closed loop to promote ecological development.

Major Features

The augmented reality system on mobile devices consists of modules such as real-time tracking and positioning, scale estimation, landmark recognition and tracking, 3D reconstruction, illumination estimation, face alignment, gesture recognition etc.

XRAPI includes the following interface modules:

  • Real-time 6DoF pose tracking: Use input data from mobile devices to calculate 6DoF pose.
  • Illumination estimation: Use video streams to calculate illumination information.
  • Scale estimation: Use input data to calculate scale information about the physical world.
  • Marker recognition and tracking: Marker recognition and tracking based on video streams.
  • 3D reconstruction: Use 6DoF pose, scale information and depth data to reconstruct the 3D model of the scene.
  • Face alignment: Predicting a set of facial keypoints from a video stream.
  • Gesture recognition: Detect hand bounding boxes and classify gestures based on video streams.

Introduction to standards

Information technology - Application interfaces of augmented reality system for mobile devices

  • Scope of application: The standard specifies the data types and interfaces for mobile device augmented reality system application development.

  • Main issues to be solved: The application interface of the mobile device augmented reality system is a bridge that realizes the interaction between the device operating system, the augmented reality engine and the application program. The application interface is an indispensable basic link to realize the augmented reality function on the mobile device.In order to further improve the compatibility of mobile device augmented reality systems and guide the design, development and application of mobile device augmented reality systems, this standard specifies the data types and interface definitions for mobile device augmented reality system application development.
