Abstract
A noncontact optical three-dimensional measuring device that includes a projector and a camera; a processor electrically coupled to the projector and the camera; and computer readable media which, when executed by the processor, causes the first signal to be collected at a first time and the second signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first signal and the distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second signal and the distance.
