Abstract:
A method for determining whether a distance that a CW-TOF range camera provides for a scene is degraded by multipath interference (MPI) comprising operating the camera to determine a propagation phase delay and a phase delay coefficient for each of a plurality of modulation frequencies of light that illuminates the scene and using the phase delay coefficient and/or the phase delay to determine whether a distance provided by the camera is compromised by MPI.

Claim (Index 21):
A continuous wave time of flight (CW-TOF) range camera comprising:\n a light source operable to transmit light to illuminate a scene that the camera images; a photosensor having pixels configured to register amounts of light reflected by features in the scene from the transmitted light; and a controller configured to:\n control the light source to illuminate the scene with light modulated at each of a plurality of M different modulation frequencies; \n for each modulation frequency, acquire frames of the photosensor that image the scene and provide for each pixel a voltage useable to provide a range image of the scene; \n for a given pixel and for each of the modulation frequencies, process the frames to determine a propagation phase delay associated with the voltages that the frames provide for the given pixel; and \n use the propagation phase delay for one or more of the modulation frequencies to determine whether the propagation phase delay is degraded by multipath interference (MPI).
