Abstract:
1. A laser projection system for projecting an image on a workpiece, comprising: a photogrammetry assembly and a laser projector, each communicating with a computer; said photogrammetry assembly including a first camera for scanning the workpiece, and said laser projector projecting a laser image to arbitrary locations with said laser image being readable by said camera, with a location of said photogrammetry assembly relative to a location of said laser projector being correlated from the laser image projected to arbitrary locations; said photogrammetry assembly signaling the coordinates of the work piece to the computer by scanning light conveyed from the direction of the workpiece with said computer being programmable for determining a geometric location of the workpiece from the light conveyed from the direction of the workpiece; and said computer establishing geometric correlation between said photogrammetry assembly, said laser projector, and the workpiece and signaling said laser projector to project a template onto a geometric desirable location of the workpiece.
