[0079] Based on the first embodiment above, in the inspection method of the transmission line in this embodiment, the step S20 specifically includes:
[0080] Step S201: Determine the first and last coordinates of the 3D point cloud in the X-axis direction.
[0081] It should be noted that the 3D point cloud in this embodiment is the original point cloud, and the 3D point cloud contains many points (tens of thousands of points). Coordinates, x1 is tail coordinates.
[0082] Step S202: Thinning the 3D point cloud to obtain a target 3D point cloud.
[0083] In this embodiment, the point cloud is uniformly thinned before the function fitting, and then the fitting is performed, which can simplify the calculation. In this embodiment, the three-dimensional point cloud can be thinned to a certain amount, for example, to 1000 points, of course, in this embodiment, the number of thinned points can also be set according to actual needs, which is not limited in this embodiment, and the...

The invention discloses a power transmission line inspection method, device and equipment and a storage medium, and belongs to the technical field of power transmission line inspection. According to the invention, the three-dimensional point cloud of the power transmission line is obtained; fitting a three-dimensional parabola of the power transmission line according to the three-dimensional point cloud; determining an inspection path of the unmanned aerial vehicle based on a preset shooting position and the three-dimensional parabola; the unmanned aerial vehicle is controlled to inspect the power transmission line according to the inspection path, a three-dimensional parabola is obtained through three-dimensional point cloud fitting, then the inspection path is determined according to the three-dimensional parabola, finally, the unmanned aerial vehicle is controlled to inspect according to the inspection path, the accurate inspection path is obtained through fitting, and later inspection result analysis is facilitated.
Description
technical field [0001] The invention relates to the technical field of transmission line inspection, in particular to a transmission line inspection method, device, equipment and storage medium. Background technique [0002] Overhead high-voltage transmission lines are an important way of power transmission in the power industry. They are directly related to the economic growth of the entire country and people's normal work and life. The safe and stable operation of transmission lines directly affects the supply of high reliability and stable power in the power system. Therefore, regular and effective inspection and maintenance of transmission lines has become an important task in the power industry. At present, the inspection of transmission lines relies on unmanned aerial vehicles to conduct inspections according to the inspection path. [0003] However, at present, most of the inspections on the status and environment of transmission line conductors and ground wires are m...
