Abstract: A method for incorporating two dimensional images such as those captured by a video camera, which is moving and whose optics, particularly zoom and focus, are controlled by a human or by automatic means, into a virtual three dimensional coordinate system is provided In one embodiment the method acquires calibration data over the functional range of the studio camera optics, and then in operation dynamically performs the appropriate transformations needed to map the video stream to the virtual coordinate system, even as the acquiring studio camera moves, zooms, and changes focus.

Abstract: A device and method for producing a model of the surface of one aspect of a three dimensional object. The model is produced by extracting a three dimensional mesh from a pattern projected on the object. The three dimensional object maybe in motion.

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.

Abstract: A method is presented that allows multiple devices for generating three dimensional surface models of moving objects to be used simultaneously. A timing pattern is used to control and trigger the devices in order to operate seven of the devices without interference. In one embodiment, a method of employing optical filters is also described that then allows operation of forty nine of the devices at the same time if the normal visible spectrum is to be used for simultaneous video acquisition. In another embodiment, if no simultaneous video acquisition is required, the optical filtering technique can support up to one hundred fifty four imaging devices operating simultaneously.
