摘要
由于大多数机械零件产品都是按一定的特征来设计制造的 ,而在实物反求中进行点云拟合时并没有按特征来进行 ,未对特征进行识别。点云拟合是反求工程的关键环节之一 ,文章对点云拟合中的特征识别技术进行了研究 ,提出了特征识别与自由曲面拟合方法相结合的三维CAD模型重构策略。
Yet most of parts of mechanisms is designed and manufactured according to certain features, but the point-cloud fitting in the object's anti-processing is not processed according the features, and doesn't identify the features. Point-cloud fitting is one of the key process in object's anti-processing, the technology of identifying features is researched in this paper, and the strategy of combining identifying features and free surface fitting is pointed out to reconstruct the model of three-dimension CAD.
