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.
