摘要:
A laser projection system is disclosed. The system includes a laser projector that projects a light beam to the surface of an object and scans that projected light beam over at least a portion of the surface, wherein a portion of the projected beam is diffusely reflected from the surface back to the system. The system further includes an optical signal detector that receives the feedback light beam and converts it to an image signal, a light suppression means for suppressing unwanted light from entering the optical signal detector, and a computer for producing a measurement of the distance from the projector to the object surface, and controlling the system to buck the laser projector into a coordinate system of the object using three or more features on the object, wherein at least one of the three or more features serves as a targetless fiducial point.
