摘要
以三维激光点云数据为基础的逆向工程技术在飞行器设计、生产制造和运营维护等各个阶段的工作中都有重要意义。点云空洞的修复是点云数据处理中最重要的环节之一。然而由于飞机机翼存在不同翼型结构的复杂性,目前常规的点云空洞修复方法对机翼点云的修复效果并不理想。文章提出了一种基于多项式插值模型的机翼点云空洞修复方法,该方法主要通过构建机翼点云剖面线多项式插值模型的方法,从线到面实现对机翼点云空洞修复。此外,还通过设置实验对照组的方法将提出的空洞修复方法与商业软件Geomagic Studio所提供的空洞修复方法进行修复精度的对比实验。实验结果表明,在针对机翼点云的空洞修复中,文章提出的修复方法的最大正负偏差值(最大+/-)、平均正负偏差值(平均+/-)和标准差(RMSE)3个空洞修复精度的评价指标都要优于Geomagic Studio软件所提供的方法。
Reverse engineering technology based on 3D laser point cloud data is of great significance in all stages of aircraft design,production,manufacturing,and operation and maintenance.The repair of point cloud hole is one of the most important links in point cloud data processing.However,due to the complexity of different airfoil structures of aircraft wings,the current conventional point cloud hole repair method is not ideal for the repair effect of wing point cloud.To solve this problem,this paper proposes a wing point cloud hole repair method based on polynomial interpolation model,which realizes the wing point cloud hole repair by constructing the wing point cloud profile line polynomial interpolation model from line to surface.In addition,this study also compared the repair accuracy of the proposed cavity repair method with the cavity repair method provided by the commercial software Geomagic Studio by setting up the experimental control group.The experimental results show that in the hole repair of wing point cloud,the maximum positive and negative deviation(maximum+/-),average positive and negative deviation(average+/-)and standard deviation(RMSE)are better than the methods provided by Geomagic Studio software.
