Cross power transmission line point cloud denoising method based on Beidou high-precision positioning

The invention discloses a crossing power transmission line point cloud denoising method based on Beidou high-precision positioning. The method comprises the following steps: step 1, correcting a crossing power transmission line point cloud through Beidou positioning information; step 2, classifying the point clouds of the crossing power transmission line; step 3, denoising the crossing power transmission line point cloud; the technical problem that the line monitoring result is affected due to the fact that the environment where the power transmission line is located is complex, the collected point cloud data is large in data size and much in noise and the point cloud data changes dynamically and seriously affects the quality of the point cloud data is solved. 本发明公开了一种基于北斗高精度定位的交跨输电线路点云去噪方法，所述方法包括：步骤1、通过北斗定位信息修正交跨输电线路点云；步骤2、对交跨输电线路点云进行分类；步骤3、对交跨输电线路点云进行去噪；本发明解决了由于输电线路所处环境复杂，采集到的点云数据数据量大、噪声多及点云数据动态变化，严重影响点云数据的质量，从而影响线路监测结果等技术问题。
