Abstract
A device and technique are presented to calibrate an imaging device for generating three-dimensional surface models of moving objects and calculating three-dimensional coordinates of detected features relative to a coordinate system embedded in the device. The internal projector and camera parameters, i.e., zoom, focus, aperture, optical center, logical pixel size, aspect ratio, are determined for all projectors and cameras and all possible focal planes of the device in operation.
