3D Reconstruction from Orthographic Projection Views Based on Solid Features

The reconstruction of 3-D solids from 2-D projections is an important research in reverse engineering. In this paper, a new method based on features for automatic reconstruction is proposed. The main features of the algorithm are to improve the speed of the reconstruction process. A 3D object is considered to be 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. These features are then combined by Boolean operations so as to form the 3D object finally. The algorithm does not match all loops of views, and 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.
