Example Embodiment

[0087] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0088] When using drones to inspect transmission lines, since the transmission line is a multi-scale and complex man-made facility, it is mainly composed of multiple sets of ground wires, insulators of various types and orientations, and drainage at both ends of the connecting tower. Lines and different types of towers and other large parts, and many small parts such as shock-proof pendants, spacers, pressure equalizing rings, and line clamps are installed in t...

Abstract

The invention relates to a processing method and system of power transmission line inspection images. According to the processing method and system, after inspection images of power transmission lines to be detected are obtained, based on feature information contained in the inspection images, only inspection images in which wires and/or towers exist are identified, and blurred and deviated inspection images are eliminated, and therefore, the number of inspection images to be analyzed can be decreased, and time for browsing and analyzing the inspection images can be shortened; the inspection images in which wires and/or towers exist are ranked, and therefore, invisible inspection images can be constructed into a tangible retrieval structure, and inspection personnel can conveniently utilize the retrieval structure to fast and effectively find defects in a power transmission circuit to be detected; and therefore, compared with the prior art, the processing method and system can greatly improve the efficiency of power transmission line inspection.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance, and more specifically relates to a processing method and system for transmission line inspection images. Background technique [0002] With the rapid development of the national economy, the demand for electric energy is increasing, which inevitably requires a more reliable power supply system. Therefore, the safe and reliable maintenance of the national grid system is of irreplaceable importance to the development of the entire national production and economy. effect. [0003] The high-voltage overhead transmission line in the power grid system is an important part of ensuring the entire power supply. Therefore, in order to ensure the safe and reliable operation of the power grid system, the high-voltage overhead transmission line must be regularly overhauled. However, due to the long transmission distance of EHV / UHV transmission lines, high towers, crossing a large number...
