Abstract
A system and method for calibrating a laser scanning system is provided. Various embodiments involve the use of a calibration plate with reference markings which is positioned to receive a directed beam in a set of known laser scanner positions. The directed beam forms a laser spot on the calibration plate, and the laser spot is captured using an image acquisition assembly such as a digital camera along with a motorized mount. The movement of the image acquisition assembly may be coordinated with the movement of the laser scanner to track the laser spot across the plate. After photographing various positions, actual laser spot coordinates are deduced from their position relative to the known positions of the reference markings.
