Power transmission line intelligent inspection system based on LiDAR

Abstract

The invention provides a power transmission line intelligent inspection system based on LiDAR and further provides a power transmission line intelligent inspection method based on LiDAR. The power transmission line intelligent inspection system comprises a three-dimensional quantifying information acquiring unit, a three-dimensional rebuilding unit and an intelligent inspection analysis unit. The three-dimensional quantifying information acquiring unit is suitable for acquiring power transmission equipment actual space three-dimensional quantifying information and power transmission line peripheral environment ground feature three-dimensional quantifying information, namely, point cloud data provided by LiDAR; the three-dimensional rebuilding unit is suitable for three-dimensional rebuilding of a power transmission line body and a corridor based on power transmission equipment actual space three-dimensional quantifying distribution information and power transmission line peripheral environment ground feature actual three-dimensional quantifying information; the intelligent inspection analysis unit is suitable for carrying out safety distance detection based on three-dimensional rebuilding results, carrying out safety distance analysis according to safety distance detection results and power transmission line safety standards and pointing out power transmission lines not catering to the safety standards or giving an alarm about the power transmission lines not catering to the safety standards. By means of the power transmission line intelligent inspection system and the power transmission line intelligent inspection method, requirements for line inspection data and function digitalization, standardization and visualization are achieved.

Description

technical field [0001] The invention relates to the field of high-voltage transmission line operation of a power system, in particular to a LiDAR-based intelligent inspection system for transmission lines. Background technique [0002] The current transportation inspection management mode of transmission lines and conventional manual operation methods are not only labor-intensive, difficult working conditions, but also low in labor efficiency, especially in the inspection of transmission lines in mountainous areas and across large rivers, as well as in ice disasters, Floods, earthquakes, landslides, power grid emergency failures and abnormal weather conditions during nights, line maintenance personnel have to rely on ground transportation or walking on foot, use ordinary instruments or the naked eye to inspect the line and deal with equipment defects, which takes a long time and manpower High cost and high risk. The existing line inspection work also has the following probl...
