Paper Abstract

Reversed Engineering of a Product Model (RPM) is a theoretical model whereby a series of high definition CCD camera images are taken of an existing facility. Through these images and an interactive CAD system, a CAD model can be created. This paper will concentrate on the basic research and tasks required to accomplish the RPM model. The research falls into two primary areas. These are (Phase 1) Image Capture; Input Image Coordinates, Control and Scale, and (Phase 2) Design and Implementation of a CAD system. The tasks for Phase 1 breakdown as follows: 1) determine method to position the camera; 2) determine lighting configuration; 3) determine common shapes and features to be considered; 4) determine pre- treatment of images before viewing; 5) determine method of viewing; 6) study how to reconstruct 3D model from 3 or more 2-D views; 7) study how to store; present and manipulate images; 8) compute image coordinate systems; 9) study the conversion of the bit-mapped data to graphics data. The tasks for Phase 2 breakdown as follows: 1) determine the requirements of the CAD system; 2) determine whether an existing CAD system can be used; 3) design and implement the CAD system.
