摘要

Switching from a coordinate measuring machine (CMM) to a laser scanning system has reduced the cost of reverse engineering automotive components by 90% while improving accuracy by a factor of 10. Generating a Class A surface model of an automobile door, for example, with a CMM required about three weeks of scanning and six weeks of surface modeling and resulted in a model whose accuracy left much to be desired. Switching to a gantry-mounted laser scanner reduced scanning time to 16 hours andsurface modeling time to 16 hours. The accuracy of models produced with the laser scanner is substantially higher than before, typically 0.001 inch over the length of a larger component such as an automotive door.
