The invention discloses a GIS equipment deformation defect automatic detection method based on unmanned aerial vehicle three-dimensional laser point cloud data. Comprising the steps of first-time data collection, first-time section model construction, first-time overall model construction, first-time error data elimination, first-time section fault analysis, second-time data collection, first-time abnormal coordinate calibration, second-time section model construction, second-time overall model construction, second-time error data elimination, second-time section fault analysis and first-time overall fault analysis. The method overcomes the defects of conventional manual detection, two-dimensional visual processing, a multi-element sensor, a satellite navigation system and other methods for detecting the deformation defect of the GIS equipment, and enables the automatic monitoring of the deformation defect of the GIS equipment to be more accurate, convenient and economical, thereby achieving the purpose of improving the operation reliability of the substation equipment.

    本发明公开了一种基于无人机三维激光点云数据的GIS设备变形缺陷自动检测方法,包括第1次数据采集、第1次区段模型构建、第1次整体模型构建、第1次错误数据剔除、第1次区段故障分析、第2次数据采集、第1次异常坐标标定、第2次区段模型构建、第2次整体模型构建、第2次错误数据剔除、第2次区段故障分析、第1次整体故障分析。本发明克服了常规人工检测、二维视觉处理、多元传感器、卫星导航系统等检测GIS设备变形缺陷方法的缺点,使GIS设备变形缺陷自动监测更加精准、便捷、经济,从而达到提高变电站设备运行可靠性的目的。
