Abstract
A CW-TOF camera that uses a piecewise constant or linear discretized indicator function of first and second modulation frequencies of light that the camera transmits to illuminate a scene and a round trip time tR for light from and back to the camera for features in the scene to disambiguate wrapped phase shifts that the camera acquires for the features.
