<p>A 3D triangulation scanner includes a projector, a camera, and a processor. At least one of the projector and the camera has a zoom lens and a motorized zoom adjustment mechanism. The processor is responsive to executable instructions that uses triangulation calculations to calculate 3D coordinates of points on a surface that are based at least in part on a baseline length, an orientation of the projector and the camera, a position of a corresponding source point on an illuminated pattern source of the projector, and a position of a corresponding image point on a photosensitive array of the camera. The 3D coordinates of the points are calculated at one time and at another time, at least one of the projector FOV being wider at the one time than at the another time or the camera FOV being wider at the one time than at the another time.</p> |
