基于形状约束的曲面重构及应用

Surface Reconstruction and Application Based on Shape Constraints

针对三维数据点重构自由曲面的光顺问题 ,探讨了一种基于形状约束的曲面重构技术。该技术基于能量优化思想 ,以物理变形能模型为目标函数 ,通过引入控制曲面形状的几何约束 ,从而实现曲面的三维重构。该方法不仅有利于重构曲面与CAD CAM系统的接口 ,而且有利于实现设计、制造、检测一体化。

On the base of the fairing of free-form surface reconstruction from 3D data points, this paper probes one method based on shape constraints. By making physical model as objective function and using geometric constraints, free form surface reconstruction is realized based on the idea of energy optimization. This method is not only beneficial to the connection of the reconstruction surface and CAD/CAM system, but also to the integration of design, manufacturing and inspection.
