AUTOMATIC MODELLING OF PHOTOGRAPHED PARTS IN CATIA CAD ENVIRONMENT

In this study, a system was developed that can model parts in catia cad program automatically by using photographic images obtained from the parts. the system, called imagecad, can use very kind of photography that was taken for prismatic and cylindrical parts. it can recognize geometric entities, such as lines, circles, arc and free curve, in the image by according to the selection of the user. imagecad can save generated knowledge of the entities in a suitable format for the catia program. imagecad, is controlled by using menus that were done in the catia interface, turn whatever you want photographs into 3b cad models. the obtained cad models have suitable structure that can be used for all catia application. visual basic programing language was preferred to design the system.
