LASER PROJECTION SYSTEM AND METHOD

摘要

A laser projection system for projecting an image on a workpiece includes a photogrammetry assembly and a laser projector, each communicating with a computer. The photogrammetry assembly includes a first camera for scanning the workpiece, and the laser projector projects a laser image to arbitrary locations. Light is conveyed from the direction of the workpiece to the photogrammetry assembly. The photogrammetry assembly signals the coordinates light conveyed toward the photogrammetry assembly to the computer with the computer being programmable for determining a geometric location of the laser image. The computer establishes a geometric correlation between the photogrammetry assembly, the laser projector, and the workpiece for realigning the laser image to a corrected geometric location relative to the workpiece.

1. A laser projection system o 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; 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.
