This is about how Kinect ranging/depth map/ works under the hood. Kinect supposedly is a TOF sensor ... that is, it measures range according to time of flight. Some systems for ranging transmit pulses and some system operate by transmitting CW [continuous wave]. Moreover, CW systems measure range ambiguously and so the systems use multiple modulation frequencies to derive unambiguous range from several ambiguous measurements -- this is part of the Kinect processing that occurs in the SDK.
Can you confirm that the Kinect is working CW? And I would like to know the modulation frequencies used for Kinect range/depth.
Also, for my problem I can work with relative ranges within a single sensed image; therefore I can use ambiguous range/depth information. How can I obtain this data ? that is, the raw Kinect sensor data without range processing and without other transformations in the SDK ?
