摘　　要：曲面重构是逆向工程的核心内容,目前大多数曲线曲面的研究都是围绕NURBS数学模型展开的。以NURBS数学模型为基础,对曲线曲面重构的方法、步骤、及其常见问题的分析处理进行了研究讨论,提出了曲线与点云相互结合重构曲面的方法,并进行了无动力排风扇叶片曲面的重构。结果表明,提出的方法是有效的和可行的,且具有一定的工程实用价值。The surface reconstruction is the core of reverse engineering.Most of the researches on the curve reconstruction and the surface reconstruction are based on NURBS at the present time.Based on the mathematical model of NURBS,this essay analyzed the method and the frequent problems of the curve reconstruction and the surface reconstruction,and put forward the surface reconstruction method of combines curve and point cloud.Finally,the surface reconstruction of non-power row fan based on this method is processed.The results show that this method is effective and feasible,and has practical value of engineering.
