反求工程CAD建模技术研究

摘要

将设计思想或实物原型迅速、直接、精确地转变为可以再加工的CAD模型，是产品创新设计和快速原型制造面临的关键技术.综合国内外反求工程CAD建模的研究和应用现状，分析了反求工程CAD建模问题的特点和需要进一步解决的主要问题，讨论了目前工程界普遍采用的反求工程CAD建模技术与思路，以及作者在解决这一系列问题中取得的进展情况.%How to transform the design idea and physical objects into a CAD model rapidly, directly and accurately is a key technique in reverse engineering (RE). It is also a bottle neck in product innovation design and rapid prototyping. After reviewing the state-of-the-art of CAD modeling in RE, some key techniques required further exploration are discussed. Some general approaches and ideas being applied to RE modeling are studied. The progress that authors have made in the related fields are also presented.
