Abstract

This study presents a simple test procedure of reverse engineering system for rapid modeling and manufacturing of products with complex freeform surfaces. Its ultimate purpose is to explore a fast, efficient, economical and experimental route to reproduction of existing physical objects with digital camera and CNC machine tools for small and medium-sized manufacturers on a P2P-based multimedia collaborative environment. This paper focuses on developing a prototype of a photogrammetry based 3D digitization, B-spline surface model reconstruction, and tool path generation based on Open CASCADE kernel. Experiments show that the method is applicable for reverse modeling of freeform objects with moderate accuracy requirements. Therefore, the presented schema is a valid alternative to laser scanning techniques and coded light-based triangulation approaches with an important reduction of the hardware costs.
