摘要
提出了基于特征及约束的反求工程参数化建模体系;研究了反求工程中特征及约束的定义、分类及表达,建立了参数化特征约束重构的最优化数学模型;探讨了参数化反求软件与通用CAD系统的集成技术;文章最后给出了一参数化曲面反求建模的实例。
Parametric technology is introduced to reverse engineering and a new scheme for parametric model reconstruction is proposed in this paper. The key techniques including definition, classification and representation of features and constraints are studied. A mathematic model is also put forward to rebuild parametric combined feature. The integration method between parametric reverse engineering software and CAD system, is discussed. Finally, an example of surface reconstruction is given to show the difference between parametric and traditional reverse engineering.
