RESEARCH ON 3D RECONSTRUCTION OF OBJECTS FROM ENGINEERING DRAWING

A novel 3D reconstruction method based on engineering drawing understanding is presented．A series of algorithms are set up．First，reconstruction processes are extended to engineering drawings containing semi-section or full section views．Second，feature recognition is made easier by analyzing the structure and semantics of engineering drawings．Third，3D reconstruction is carried out together with feature recognition so that the reconstruction result can be further processed at a high level of intelligence．
