摘要
机载激光雷达(LiDAR)技术的快速发展为获取高时空分辨率的地球空间信息提供了一种全新的技术手段。笔者在某市电力选线项目中利用机载激光雷达技术,获得高精度点云,根据点云建立三维模型,并通过大量外业采集数据进行精度检核,最后将生成产品导入电力选线软件中,实现了在室内完成电力选线工作。实验表明,在电力选线项目中,利用机载激光雷达技术提高了作业效率,具有广阔的应用前景。
The rapid development of the LiDAR technology provides a new technical means for obtaining high space -time resolution of earth space information .Author used LiDAR technology to obtain high accuracy point cloud ,which based on point cloud to set up 3D model, checked the accuracy through a lot of data from the field , put the products into the power line selection software and com-pleted route choice of electric power indoor in a certain area of Sichuan .Experimental results show that using LiDAR technology can improve the working efficiency greatly and has wide application prospects in route choice of electric power .
