基于随机采样一致算法的卡车车厢点云分割
Point cloud segmentation of truck compartment based on RANSAC algorithm
摘要
Abstract
To address the challenge of segmenting truck bodies due to their diverse types and the difficulty in segmenting deformed compartments,a segmentation approach based on RANSAC is proposed.Initially,the compartment surface is evenly divided to obtain multiple planar patches.A Kd-tree is employed to establish topological and geometric relationships among these patch point clouds.The Euclidean distance from a point to a plane is used as the criterion for initial segmentation,with a distance threshold applied.Subsequently,an angle threshold is de-signed in conjunction with the RANSAC algorithm to optimize and merge the patches,achieving precise segmen-tation of various types of truck bodies.The experimental results demonstrate that the truck segmentation model developed can segment multiple types of truck bodies.Specifically,the maximum relative errors in measuring the dimensions of double-sided,four-sided,and five-sided trucks are 0.048,0.031,and 0.046 m,respectively.The measurement accuracy meets engineering requirements.关键词
