Abstract:
The new products or tools development are often based on already existing products, prototypes or physical models, mostly very complex shapes. Such free form surface can be accurately reconstructed only on the basis of a large number of measuring points. By the classic measuring methods, it is very difficult or impossible to measure sufficient number of points. The digitization is realized by and ATOS measurement systems. A result of digitization with optical measuring system ATOS is detailed poligonized mesh or point cloud. Depending on application, creating of the model’s surface is carried out with introduction of certain assumptions and approximations, based on knowledge of processing technology of model whose geometry is reconstructed. All commands necessary for reconstruction are placed in CATIA Workbenches under group Shape. The presented procedure is hardware- and time-consuming. It generates accurate digitized object’s surface, mathematically defined by NURBS.
