Abstract
A laser scanning method and system for determining an outline of an object. A laser beam is projected at the object and a surface underlying the object. The surface is configured to reflect the laser beam differently than the object. The laser beam is reflected off the object and the surface producing reflected beams. The reflected beams are received by a control which determines whether the beam was reflected from the object or the surface. By identifying this with the laser position the control can identify the part outline. As the laser beam is scanned over successive positions along the surface, the outline of the object is precisely determined.
