基于逆向工程的船用螺旋桨数字化检测方法

A New Digital Detection Method of Marine Propeller Based on Reverse Engineering

针对传统螺旋桨检测方法操作困难、效率低、检测精度差等问题,采用三维激光扫描仪对船用螺旋桨进行测量并获得完整的三维点云数据,利用CATIA软件对点云数据进行预处理,对处理后的点云进行模型重建得到满足精度要求的曲面,对重建的螺旋桨模型与设计模型进行偏差分析,得到桨叶上各点的偏差值,通过该方法可以实现船用螺旋桨的数字化检测。

In view of the problems of difficult operation,low efficiency and poor detection precision of the traditional propeller detection method,a three-dimensional laser scanner was used to measure the marine propeller and obtain complete 3D point cloud data.The CATIA software was used to preprocess the point cloud data,and the processed point cloud was reconstructed to meet the accuracy requirement.The deviation analysis of the reconstructed propeller model and the design model were acquired by the CATIA,and the deviation of each point on the blade was obtained.This method can realize the digital detection of the marine propeller and save time and labor.
