A Method for Repairing Holes in Aviation Blades Based on Line Laser
摘要: 针对航空叶片的孔洞修复问题，本文提出了基于线激光的孔洞修复方法。使用Alpha Shape边缘轮廓提取算法提取航空叶片的内外边缘，使用基于KD树的欧几里德分割算法分割出孔洞部位的边缘，接着使用基于最小二乘的点云曲线拟合算法，根据线激光扫描的点云线条拟合曲线方程，再将孔洞区域的边缘数据导入拟合后的曲线模型得到孔洞部位曲面数据，完成航空叶片孔洞的修复工作。
Abstract:
For the repair of holes in aviation blades, this article proposes a hole repair method based on line laser. Using the Alpha Shape edge contour extraction algorithm to extract the inner and outer edges of aviation blades, using the KD tree based Euclidean segmentation algorithm to segment the edges of the hole area. Then, using the least squares based point cloud curve fitting algorithm, fitting the curve equation based on the point cloud lines scanned by line laser, and importing the edge data of the hole area into the fitted curve model to obtain the surface data of the hole area, Complete the repair work of aviation blade holes.
