Research o nProduct Reverse Analysis Based on ICT Image

摘要

This paper presents and approach fo product reverse analysis based on ICT slicing inage. It includes the detection of dominant points on edge lines, inside andoutside boundaries recongnition based on simple loop, solid modeling, 3D machining features recongnition based on 2D drawing features and the relation determination of corresponding drawing feature between successive ICT image slices. The accuracy fo solid models ahd been improved through above methods and the key techniques for accuracy improvement of 3D modeling are analyzed. The research work can help design engineers to analyze the proudct's design ideas, operation principle and construction charaters.
