A system and method are presented for calibrating a set of imaging devices for generating three dimensional surface models of moving objects and calculating three dimensional coordinates of detected features in a laboratory coordinate system, when the devices and objects are moving in the laboratory coordinate system. The approximate location and orientation of the devices are determined by one of a number of methods: a fixed camera system, or an attitude sensor coupled with an accelerometer, a differential GPS approach, or a timing based system. The approximate location and orientation of the device is then refined using to a very highly accurate determination using an iterative approach and de-focusing calibration information. |
