Problems solved by technology

[0003] Due to the wide distribution area of ​​transmission lines, long transmission distance, complex and changeable terrain conditions, and strong weather influence, it is necessary to know the situation of various power facilities on transmission lines in real time. However, faults on transmission lines sometimes have Due to the characteristics of concealment and suddenness, it is difficult to achieve timely fault warning only by relying on the manual inspection of electric power workers.

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] Generally speaking, the recognition in the existing technology is mainly static recognition, and most of the current image recognition technologies (such as face recognition technology), all have many restrictions on the recognition of objects, such as must be stable, mainly in a static state; need to compare With good background conditions, there should be no too many interference objects; when the recognition effect is not good, it is difficult to adjust, etc. In addition, there are few algorithms for industries: the current image recognition technology is mainly based on characters, faces, logo graphics, etc., and there are very few targeted algorithm developments for common devices in a certain industry, such as the power industry.

Abstract

The invention provides an unmanned aerial vehicle-based intelligent identification method of electric power facilities. The method includes: carrying out lidar scanning on a to-be-patrolled power lineto obtain three-dimensional point cloud data of the to-be-patrolled power line, and carrying out key feature screening to extract and obtain key feature point information; combining position data inthe three-dimensional point cloud data to determine key point patrolling positions and key point patrolling targets of a current patrolling process on the basis of the key feature point information togenerate flight path planning data of the current patrolling process; collecting image data of the key point patrolling positions and the key point patrolling targets in a process of flying accordingto the flight path planning data; and carrying out content identification processing on the image data through a special image processing identification module to troubleshoot fault conditions existing in the to-be-patrolled power line. According to the method, optimal setting can be carried out for both positions and angles of shooting of the key point targets through refining platform handlingand controlling, and patrolling efficiency and accuracy of image identification are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an intelligent identification method and system for electric power facilities based on an unmanned aerial vehicle. Background technique [0002] The safe and reliable operation of power facilities is related to economic development and the normal operation of social life. Transmission lines are an important part of the power system. Ensuring the normal operation of transmission lines is the premise and guarantee for the safe operation of the entire power system. [0003] Due to the wide distribution area of ​​transmission lines, long transmission distance, complex and changeable terrain conditions, and strong weather influence, it is necessary to know the situation of various power facilities on transmission lines in real time. However, faults on transmission lines sometimes have Due to the characteristics of concealment and suddenness, it is difficult to achieve...
