ABSTRACT:
An improved method of calibrating a laser projector to reference points includes the steps of moving a reflective member in the path of a laser beam. The reflective member is moved towards a reference point, and a control for the laser projector operates in one mode of operation to move the laser beam with the reflective member. The reflective member is moved, and moves the laser beam towards one of the reference points. Once the laser beam is adjacent to the reference point, the reflective member is removed from the laser beam member. The laser projector then identifies the location of the reference point, and begins to calibrate itself relative to the work surface. This process is repeated until the calibration is complete.
