Important Notice

We are happy to announce that the RealSense GitHub repositories have been successfully migrated to the RealSenseAI organization. Please make sure to update your links to the new RealSenseAI organization for both cloning the repositories and accessing specific files within them.

https://github.com/IntelRealSense/librealsense --> https://github.com/realsenseai/librealsense

Note 1: A redirection from the previous name IntelRealSense is currently in place, but we cannot guarantee how long it will remain active. We recommend that all users update their references to point to the new GitHub location.

Note 2: Users who install the SDK via APT are required to update the APT key as explained in the following guide

Branch Policy

We have updated our branch policy: From now on, we will also push beta releases to the master branch, so users can access up-to-date code and features. In the near future, beta binaries will also be pushed to public distribution servers (e.g., APT). The last validated official release can be found on our Releases page on GitHub.

Use Cases

Below are some of the many real-world applications powered by RealSense technology:

Getting Started

Start developing with RealSense in minutes using either method below.

1️. Precompiled SDK

This is the best option if you want to plug in your camera and get started right away.

Download the latest SDK bundle from the Releases page.
Connect your RealSense camera.
Run the included tools:
- RealSense Viewer: View streams, tune settings, record and playback.
- Depth Quality Tool: Measure accuracy and fill rate.

Setup Guides - precompiled SDK

Note: For minor releases, we publish Debian packages as release artifacts that you can download and install directly.

2️. Build from Source

For a more custom installation, follow these steps to build the SDK from source.

Clone the repository and create a build directory:

git clone https://github.com/realsenseai/librealsense.git
cd librealsense
mkdir build && cd build

Run CMake to configure the build:
```
cmake ..
```
Build the project:
```
cmake --build .
```
