The invention provides a real-time detection method for the safe distance of ground objects under the power line. By registering the laser point cloud data and image data in real time, the color laser point cloud in the area near the power line is generated in real time, and then the color point cloud is processed by using a deep learning algorithm. Real-time classification to obtain the 3D laser point cloud corresponding to the power line, and then use the laser point cloud data to fit the sag equation of the power line in real time to obtain a 3D model of the power line, and finally use the plumb line method to detect the safe distance of the ground objects below in real time. In the present invention, the whole process is fully automated without manual intervention, and real-time detection of the safety distance of ground objects under the power line is realized.
Description
technical field [0001] The invention relates to the technical field of power line detection, in particular to a method for real-time detection of the safety distance of ground objects below the power line. Background technique [0002] The current high-voltage power lines in my country's power grid have complex structures and large scales, and the line channel environment is very complicated. Foreign objects, trees under the lines, illegal construction, and illegal buildings can easily lead to insufficient line safety distances and short-circuit accidents. Once an accident occurs, the consequences will be serious. The huge current may cause serious injury to personnel, and the fault will cause damage to line equipment, tripping and outage, which will impact the operation of the power grid. At the same time, the fault will affect the power supply in urban areas and disrupt the normal production and life of enterprises and residents. order, resulting in major economic losses. ...
