Graph-based Surface Merging in CAD-guided Dimensional Inspection of Automotive Parts
نویسندگان
چکیده
A CAD-guided camera planning system for dimensional inspection of automotive parts has been developed in this paper. This system utilizes the CAD information of inspected parts and the camera model to plan camera viewpoints that satisfy certain task constraints. To overcome some limitation inherited in the existing method, a new CAD data representation is adopted to combine the advantages of parametric surface and triangulation. A graph-based surface merging algorithm is proposed to reduce the number of at patches, eventually, the number of viewpoint. Tests on di erent real part models show that the surface merging algorithm is e ective. This algorithm can also bene t many other CAD-guided robot path planning applications.

A CAD-guided vision sensor planning system is developed in our lab. To improve the efficiency of the inspection system, the path planning problem is rendered as a Traveling Salesman Problem(TSP). A new approach is developed to solve the TSP into its suboptimality quickly. First, viewpoints are clustered into several groups. Second, clustered Traveling Salesman Problem is solved by favoring the ...
