Comprehensive design recovery for mechanical components

在逆向工程领域，为了检查和设计恢复的目的，正在进行许多关于捕获对象形式的研究。当使用当代逆向工程技术重建一个对象时，沿着对象的表面收集许多三维数据点。利用最佳拟合多项式方法从点云数据构建曲面。由于误差（由于扫描和制造技术，磨损等），点云数据不对应于理想的副本；因此，设计修改可能是必要的。此外，除非使用计算机断层扫描（CT）扫描，否则使用现有方法模型是不完整的，这是成本过高的，因为数据收集系统不容易捕获关于凹陷或内部特征的信息。

In the area of reverse engineering, much research is being done on capturing the form of an object for inspection and design recovery purposes. When using contemporary reverse engineering techniques to reconstruct an object, many three dimensional data points are collected along the object's surface. Surfaces are constructed from the point cloud data using best-fit polynomial methods. Because of errors (due to scanning and manufacturing techniques, wear, etc.), the point cloud data does not correspond to an ideal replica; therefore, design modifications may be necessary. In addition, the model is incomplete using existing methods unless computer tomography (CT) scans are utilized, which is cost prohibitive, as data collection systems do not readily capture information on recessed or internal features.
