Research of 3D part reconstruction from Orthographic Projections Based on Solid Features

Abstract A new method based on solid features for automatic reconstruction is proposed in this paper. The main features of the algorithm are to improve the speed of the reconstruction process. A 3D object is composed of one, or more than one part. The idea of the algorithm is to extract closed loops from orthographic views and to match loops from two views in order to build features, which are then combined by Boolean operations so as to form the 3D object finally. The algorithm does not match all loops of views, while redundant loops are deleted when feature is found. The example from a working implementation is given to demonstrate the efficiency and capability of the proposed algorithm
