摘　　要：基于逆向工程技术对风力机叶片实体进行建模。应用三维数字化激光扫描测量技术,采集叶片实体表面点云,在对数据点云进行预处理后,采用NURBS曲面拟合方法,实现叶片实体模型的重构,进而为风力机风轮气动性能及风洞试验方面的研究提供所必要的叶片实体模型。Based on reverse engineering technology, the wind turbine blade entity model was built. The blade entity surface＇s points cloud was collected by 3D digital laser scanning measurement technology and was pretreatment, the blade entity model＇s reconstruction was implemented by NURBS surface fitting method, which provides the essential blade entity model for the research on the aerodynamic performance and wind tunnel test of the wind turbine rotor.
