摘要
点云数据处理以及点云的曲面、曲线拟合是逆向工程中一个重要的研究课题,其重要任务就是将实际物理模型重建生成几何模型,而核心问题就是如何从采样点出发重建曲线、曲面模型。本文以C++开发平台和MATLAB为基础,对三维激光扫描数据利用B样条、NURBS、三角网格曲面拟合方法和曲线拟合方法进行研究探索。
Point cloud data processing and point cloud of curved surface and curve fitting in reverse engineering is an important re -search topic .Reverse engineering is an important task to actual physical model reconstruction , but the geometric models generated from the core problem is how to reconstruct the sampling point curve and surface model .C＋＋development platform and MATLAB based on 3D laser scanning data using B -spline, NURBS, triangular mesh surface method and the curve fitting method of research and exploration .
