Abstract

The embodiments of the invention provide a method and apparatus for detecting the tilt-over level of a pole tower. The method is applied to aerial photography devices. The method herein includes the following steps: an aerial photography device acquiring the laser radar data and image data of a target pole tower; based on the point cloud and image registration of direct linear transformation, thelaser radar data and the image data, generating color point cloud data; based on a pre-saved machine learning classification algorithm and sample data, acquiring the point cloud data of the target pole tower; and based on the point cloud data of the target pole tower, calculating the tilt-over rate of the target pole tower. The method herein can automatically measure the tilt-over level of a powerpole tower in a large area in an accurate manner, can present measurement data in images and data, and can facilitate achieve and follow-up management. Also, the method can avoid the problems of current measurement methods, such as heavy workload, high risks, and low efficiency.

Description

technical field [0001] The invention relates to the technical field of transmission line detection, in particular to a method and a device for detecting the inclination degree of a tower. Background technique [0002] The tower is one of the basic equipment in the transmission line, and the measurement of its inclination is an important part of the construction and operation and maintenance of the line. Because the pole tower is exposed to the outside for a long time, it is vulnerable to natural erosion and man-made damage, and it is prone to deformation or tilting, resulting in too small electrical safety distance, and even broken poles may occur. In urban areas or other densely populated areas and important intersections, once the tower falls, the consequences will be very serious. With the completion and operation of UHV transmission lines in my country, how to measure the inclination of transmission line towers with high precision and high efficiency is a matter of grea...
