Structural auto-archiving method for unmanned aerial vehicle inspection images of power transmission line

Abstract

The invention discloses a structural auto-archiving method for unmanned aerial vehicle inspection images of a power transmission line. Geographic longitude and latitude coordinates collected by an unmanned aerial vehicle positioning chip when photographing is carried out are added to blocks of an image file EXIF collected by inspecting the power transmission line through an unmanned aerial vehicle; geographic position coordinate information stored in the image file collected by inspecting the power transmission line through the unmanned aerial vehicle is analyzed; the geographic position coordinate information is compared and analyzed with geographic coordinate information of power transmission towers in a production standing book; auto-archiving of the unmanned aerial vehicle inspection images taking towers and line sections as objects is realized; and the firm foundation is laid for further analysis and application of inspection image data.

Description

technical field [0001] The invention relates to the technical field of state monitoring and fault diagnosis of electric power equipment, in particular to a structured automatic archiving method for UAV inspection images of power transmission lines. Background technique [0002] In recent years, UAVs have been applied in the inspection of overhead transmission lines in the power industry. The National Energy Administration promulgated DL / T 1482-2015 "Technical Guidelines for UAV Inspection Operations on Overhead Transmission Lines", China Southern Power Grid Corporation issued "Technical Specifications for Overhead Transmission Line Machine Patrol Photoelectric Pods (Trial)", State Grid Corporation of China Q / GDW 11383-2015 "Guidelines for Configuration of UAV Inspection System for Overhead Transmission Lines" was released to regulate the UAV inspection system. The popularization and application of these standards provides support for the widespread application of UAV techno...

Problems solved by technology

The monitoring of this system is only for the GPS information of the UAV, and it cannot effectively archive and classify the image information collected by the UAV's real-time flight inspection, and it has not been applied in the power system inspection business.

[0008] Some technologies realize real-time monitoring of UAV line inspection data through the ground control station, and upload the inspection image information to the Internet through the 3G channel, which can only realize the remote monitoring of the image, and does not have the result data of the inspection For subsequent automatic processing, especially between the monitoring system and the UAV, only one-to-one monitoring can be performed, and it is impossible to effectively classify the information collected by multiple UAV inspections at the same time, resulting in low data utilization efficiency and data business value not shown

[0009] To sum up, the existing monitoring image information collection and archiving methods for UAV inspections are not ideal, and there are still many problems to be solved. Or automatic archiving and analysis of video images to determine whether there are line defects and channel obstacles that are difficult to identify manually, such as wire breakage, insulator damage, tree line distance, ice thickness, sag change, etc., nor can it be based on the preset report template. Automatically generate a list of hidden danger information of the line, so as to provide the first early warning information for the operation and maintenance of the line
