基于特征的曲面模型重建方法

曲面重建就是根据曲面实物模型的点云，重建其几何和拓扑信息，并再现特征的过程，复杂曲面重建质量直接影响曲面产品的性能，影响后续设计分析和制造加工，为了提高重建曲面质量，满足产品对其光顺和精度要求，文章对曲面重建中的几何建模技术和光顺，连续性的束条件进行了系统地分析研究，对基于特征的曲面模型重建方法进行了探讨，最后结合摩托车车身覆盖件3D模型设计给出了应用实例。

Feature-based Surface Model Reconstruction Technique

Surface reconstruction is reproduction process of geometric topology information and feature bases on surface practicality model. The quality of surface reconstruction directly influences performance of production, analysis and manufacture. To improve quality of design and meet requirement of fair, precision, it's researched by the numbers the geometric modeling and constraint of surface reconstruction. Feature-based surface model reconstruction technique is discussed in this article. Combine with 3D model design of motor body covering, an engineering application is given finally.
