【摘要】：以标准球作为测量基准,以线扫描激光传感器作为测量手段获取透平叶片的全数据测量点云.测量设备采用四坐标测量机搭载激光线扫描传感器的方式,以保证叶片的测量效率,并兼顾测量机的控制准确度.通过测量机获得透平叶片的点云数据,并对获得的截面点云数据进行误差补偿、去噪、简化等预处理操作,利用非均匀有理B样条曲线拟合算法得到叶片特征曲线.实验结果证明该方法可以有效地提高叶片前后缘的重构准确度,并为叶片的三维建模提供更为准确的原始数据.
[Abstract]:Taking the standard ball as the measuring datum and using the line scanning laser sensor as a measuring method to obtain the full data measurement point cloud of the turbine blade. The measuring equipment uses the four coordinate measuring machine to carry the laser line scanning sensor to ensure the blade measurement efficiency and take into account the control accuracy of the measuring machine. Point cloud data are used to make error compensation, denoising, simplification and other preprocessing operations. The blade feature curves are obtained by using the non uniform rational B spline curve fitting algorithm. The experimental results show that the method can effectively improve the reconstruction accuracy of the blade edge and provide more accurate 3D modeling for the blade. Raw data.
