Abstract

The emergence of commercial time of flight (ToF) cameras for realtime depth images has motivated extensive study of exploitation of ToF information. In principle, a ToF camera is an active sensor that emits an amplitude modulated near-infrared (NIR) signal, which illuminates a given scene. The per-pixel phase difference of the modulation between reflected light and a reference signal determines the path length, and hence a depth map, of the scene.
