A Path Planning Model Based on Point Structure in On-Line Reverse System

The reverse engineering general with coordinate measuring machine or 3D scanner realize the parts digital，and the measuring equipment is very expensive which limit the reverse engineering application. To solve this problem, this paper uses the higher precision walking mechanism of numerical control machine, adds the special online probe to compose a digital measuring equipment ；it uses the CAD sketch model to drive, which researches the basic representation method of the path information，the distribution form of the measuring point in the different characteristic element，the distinction between the measuring point，the attribution rules and the derived form of the path information of the measuring point. It also includes the development of dedicated reverse soft and the automatic generation of the measuring program reverser path. This method provide a new low cost reverse engineering means which decrease measured data and simplify the reverse engineering.
