三维散乱数据曲面重构技术综述

A Survey of Curved Surface Reconstruction Technique from 3-D Scattered Data

三维散乱数据白面重构技术是复杂曲面测量几何造型系统的关键技术。它有整体拟合和局部拟合两种方法。局部拟合因其具有与通用CAD系统相同的数学模型,所以它是复杂曲面测量几何造型系统的常用方法。目前,国内外专家学者在这方面做了大量的理论研究和实际探索,并取得丰硕成果。这种将测量系统与造型系统结合起来的曲面重构技术在工程实际中具有广阔的应用前景。

The technology on curved surface reconstruction from 3-D scattered data is the key technology of measure and geometric modeling systems for complicated curved surface. It includes unitary fitting and local fitting methods. The local fitting method is a common method of measure and geometric modeling systems for complicated curved surface because of its mathematical model the same as that of current CAD system. The technology, which links a measure system and geometric modeling system, will take on a wide prospect in practical application of engineering. At present, domestic and foreign experts have acquired plentiful and substantial achievements theoretically as well as practically.
