Intel® RealSense™ Cross Platform API

Platform Build Status
Linux and OS X Build Status
Windows Build status

This project is a cross-platform library (Linux, Windows, Mac) for capturing data from the Intel® RealSense™ F200, SR300, R200, LR200 and the ZR300 cameras. This effort was initiated to better support researchers, creative coders, and app developers in domains such as robotics, virtual reality, and the internet of things. Several often-requested features of RealSense™ devices are implemented in this project, including multi-camera capture.

Developer kits containing the necessary hardware to use this library are available for purchase at this link. This project is separate from the production software stack available in the Intel® RealSense™ SDK, namely that this library only encompasses camera capture functionality without additional computer vision algorithms.

The Intel® RealSense™ Cross Platform API is experimental and not an official Intel product. It is subject to incompatible API changes in future updates.

A comprehensive suite of sample and tutorial applications are provided in the /examples subdirectory. For new users, it is best to review the tutorial series of apps which are designed to progressively introduce API features.

  • C API - With doxygen-style API comments
  • To build documentation locally from sources, on Ubuntu run the following commands:
    • sudo apt-get install doxygen
    • doxygen doc/Doxygen_API/Doxyfile

  1. Native streams: depth, color, infrared and fisheye.
  2. Synthetic streams: rectified images, depth aligned to color and vice versa, etc.
  3. Intrinsic/extrinsic calibration information.
  4. Majority of hardware-specific functionality for individual camera generations (UVC XU controls).
  5. Multi-camera capture across heterogeneous camera architectures (e.g. mix R200 and F200 in same application)
  6. Motion-tracking sensors acquisition (ZR300 only)

Compatible Devices

  1. RealSense R200
  2. RealSense F200
  3. RealSense SR300
  4. RealSense LR200
  5. RealSense ZR300

Compatible Platforms

The library is written in standards-conforming C++11 and relies only on the C89 ABI for its public interface. It is developed and tested on the following platforms:

  1. Ubuntu 14.04 and 16.04 LTS (GCC 4.9 toolchain)
  2. Windows 8.1 and Windows 10 (Visual Studio 2015 Update 2)
  3. Mac OS X 10.7+ (Clang toolchain)
  4. Ostro

Hardware Requirements

Developer kits containing the necessary hardware to use this library are available for purchase at this link. In addition, several consumer tablets and laptops with integrated cameras may also function, such as the HP Spectre x2 with R200.

Developer kits require USB 3.0. RealSense™ cameras do not provide backwards compatibility with USB 2.0. Not all USB host chipsets are compatible with this library, although it has been validated with recent generations of the Intel Host Controller chipset. An exhaustive list of incompatible hardware is not presently provided. On x86, a Haswell or newer architecture is recommended.

For small-form factor usages, this library has been demonstrated to work on the following boards:


The library has been integrated with a number of third-party components and operating systems. While most of these projects are not directly supported by the team, they are useful resources for users of this library.
