Introduction

English | 简体中文

XRPrimer is a fundational library for XR-related algorithms. The XRPrimer provides reusable data structures, efficient operaters and extensible interfaces both in C++ and Python.

Major Features

  • Various camera models and conversion tools (Pinhole, Fisheye, Omni etc.)
  • Basic 3D operations (Triangulation, Projection etc.)
  • Multi-camera extrinsic calibration tools
  • Rendering and visualization tools

Operation Systems

It currently supports the following systems.

  • Linux
  • iOS

Installation

Python

If using xrprimer in a Python project, it can be installed by:

pip install xrprimer

If you want to use the latest updates of xrprimer, please refer to Python Installation for detailed installation.

C++
