Then discusses the optical measurement method especially, founds a method and step about digitized measurement of large-scale complex parts. The ATOS optical scanning system is used to measure the automobile bonnet, gauge board, etc.

• 重点讨论了光学测量方法,利用ATOS光学扫描系统,以大尺寸复杂零件汽车引擎盖、仪表盘等的数字化测量为实例,找到了数字化测量大型复杂零件的方法和步骤。
