摘　　要：输电线路通常需要穿越各种的复杂地貌,导致输电线路路径的施工难度极大、成本极高,因此研究了阵列干涉激光雷达点云滤波在输电线路路径优化设计中的应用。将使用阵列干涉激光雷达收集的输电线路环境三维点云数据进行滤波降噪,同时构建点云数据空间索引模型,进而利用随机森林算法从空间索引模型中提取输电线路路径特征并以此优化路径选择。实验数据显示,该方法的综合评分值为91.357 8,降低了对环境的影响和建设成本,提高了能源传输效率。Transmission lines usually need to traverse various complex landforms,which makes the construction of transmission line paths extremely difficult and costly.Therefore,the application of array interferometric LiDAR point cloud filtering in the optimization design of transmission line paths was studied.This paper will filter and denoise the three-dimensional point cloud data collected from the transmission line environment using array interferometric LiDAR,and construct a spatial index model for the point cloud data.Then,this paper will use the random forest algorithm to extract the path features of the transmission line from the spatial index model and optimize path selection accordingly.The experimental data shows that the comprehensive score of this method is 91.3578,which reduces the impact on the environment and construction costs,and improves energy transmission efficiency.
