RealSense cameras achieve their accuracy through a clever hardware design that combines stereo vision with an active infrared projector. Unlike passive systems that rely solely on ambient lighting, the structured-light approach projects a texture pattern onto the scene, allowing the camera to compute depth even on smooth or featureless surfaces. This capability unlocks substantial potential for operating robots indoors, where controlled lighting and uniform surfaces can defeat conventional stereo cameras. For researchers working in laboratories, warehouses, and other indoor environments, this robustness translates directly into more reliable experimental results.
