曲面重构技术是逆向工程中CAD建模的重要组成部分．基于三维散乱点云的曲面重构技术更是当前研究的热点。针对三维扫描数据点的曲面重构技术在实际系统中的应用，本文以三维散乱点云为研究对象，提出了一种非均匀有理B样条曲面构造方法，该方法根据已知数据点逼近目标曲面。通过系统应用验证，该方法是一种行之有效的曲面拟合重构方法。

Surface reconstruction is an important part of CAD technology modeling in reverse engineering, surface reconstruction of scattered point cloud technology based on three-dimensional is a research focus. To the application of surface reconstruction of three-dimensional scan data points in the actual system, the article take this three-dimensional scattered point cloud as the research object, proposed a non-uniform rational B- spline surface construction method, which targets according to the known data point approximation surface.Through the system application, this method is an effective method of surface fitting reconstruction.
