Applied research of UG and imageware in 3-D Model reconstruction of reverse engineering

Reverse engineering technology is an important means of modern product design.As a new method for absorbing the advanced technology,reverse engineering is the main means of the advanced technology.Three-dimensional CAD model reconstruction is the key step in reverse engineering.It introduces the concept of reverse engineering and key technologies,analyses the application features of UG software in the field of reverse engineering,as well as the methods and process for surface structure in the UG software.The author summarizes the advantages of point cloud date handing and date processing process in Imageware software.The geometric date for automobile body parts is collected by applying the LSH-600 type non-contact 3d laser scanner and the process of collecting date is described in detail Finally the 3-D model of the automobile parts is taken as an example of reconstruction to illustrate the restructuring process combining the respective advantages of Imageware and UG.
