ABSTRACT:
A laser imaging system and method of projecting a laser template on a surface, including independently determining a position and orientation of the surface using an external metrology device, independently determining a position and orientation of a laser projector using the metrology device, generating a signal from the metrology device to a computer and orienting the laser projector relative to the surface to project a laser template. The apparatus includes a plurality of metrology transmitters at fixed locations, a plurality of metrology receivers at fixed locations relative to the surface and a plurality of metrology receivers at fixed locations relative to either the laser projector or laser targets within a field of view of the laser projector. A laser projector and frame assembly is also disclosed, wherein the metrology receivers are located on the frame and the frame includes laser targets for correcting laser drift. Kinematic supports for the metrology receivers are disclosed as well as an independent laser tracker.
