rs-sdk

Cross-platform C++ library for Intel RealSense depth cameras (D400 series and L515) providing high-level control over 3D data streams.

The Intel RealSense SDK 2.0 (librealsense) provides the essential interface for depth-sensing hardware like the D435i and D455. It supports multiple languages (C++, Python, and C#) and integrates directly with frameworks like ROS and Unity. Developers leverage the `realsense-viewer` for real-time debugging and the `rs-enumerate-devices` tool for hardware diagnostics. The library manages complex tasks: spatial filtering, temporal alignment, and point cloud generation. It remains the industry standard for building vision-based systems in robotics and spatial computing.
