摘要
提出了一种基于3D点云深度信息的函数拟合与三角剖分相结合的方法,构建了高速滑动电接触构件的表面损伤特征提取模型,将损伤区域3D特征数据进行三角剖分,计算了构件表面损伤体积和质量。实验结果表明,该算法计算准确度可达97.3%。
One method which combines the triangulation and the function fitting based on 3D point cloud depth information is proposed. The extraction model of surface damage features in high speed sliding electric contact components is built. The 3D feature data in the damaged area are divided into triangulation and the surface damage volume and mass of the components are calculated. The experimental results show that the accuracy in computation of the proposed algorithm can reach 97.3%.
