Calibrating Time-Of-Flight Cameras


By applying clever calibration and compensation methods, distance errors of a Time-of-Flight camera can be significantly reduced. However, to achieve this, the TOF camera needs a calibration of every pixel at several distances over the full pixel field.

Commonly this requires a space consuming setup with the camera mounted on a stage with a moving target plate. It also needs substantial time. For larger field of views, typically only the center part of the pixel field is calibrated for practical reasons.
