摘要
对自由曲面重构中存在的问题进行了分析 ,提出以自动计算特征线为参考 ,进行交互建模的思路。对交互建模中反求目标的确定、点云分块边界的处理、模型框架的要求以及曲面拟合边界的选择进行了阐述 ,对交互建模的两种特殊情况 ,给出了曲面重构方案。实践表明该建模方法可以得到工程中满意的曲面模型。
This paper presents a interacted-modeling methods, which is based on how to interact with the computer to generate the desired CAD model with referencing the outcome of the automatic algorithm.Further more,this paper introduces how to determine the aim of RE ,the boundary of the segmented point clouds, the requirement of model framework and fitted surface boundary selection. Finally the described methods are illustrated with two special examples. The practical engineering application of RE suggests that the interacted-modeling method can meet the engineering needs.
