车载LiDAR数据电力线与塔杆提取方法
Extraction of Power Lines and Poles Based on Mobile LiDAR Data
摘要
Abstract
To implement the extractions of the power lines and poles with the data of mobile LiDAR,a new method was proposed on the fundamental of analyzing the features of power lines.Firstly,a mass of ground points were removed by using elevation distribution histogram statistics method.Secondly,the k-means was adopted to get separated power lines and poles point cloud,and then,the positions of poles were located with the help of their density characteristics.At last,a single power line could be extracted according to the power line's direction and the smaller-dispersion feature in the identical line.Then the polynomial model was used to establish the power line model.Experimental results showed that this method could achieve the factors' extraction of power lines well,although in complex areas.关键词
