| Abstract: | The 3D profile measuring technology is an important approach,and composite surface modeling is the main content for researching in reverse engineering.The principle of laser scanning system and the types of cloud data are argued.For grid data,a quick and efficacious method for modeling is designed.It includes the cloud data smoothing,the character line extracting,the cloud data segmenting and the surface constructing,which were illustrate by anexample. |
