Problems solved by technology

The existing sharpness evaluation methods use simple edge width or energy discrimination methods to analyze the blur degree, which is difficult to apply to complex situations with a wide variety of targets. Moreover, the existing technology lacks research on the shooting quality inspection system, and simple image quality evaluation is difficult. Ensure that the quality inspection results can be effectively used in transmission line inspection operations

Abstract

The invention provides an online quality inspection method for power transmission line equipment, S1, video and image collection of target equipment; S2, real-time detection of key target equipment in the video image based on the target real-time detection algorithm, positioning each The location area of ​​the key target equipment; S3. Perform quality checks on the exposure, clarity, and shooting angle of the inspection video images and captured images in the location area of ​​the target equipment. The present invention solves the problem of target-level quality evaluation. The present invention conducts quality checks on the key equipment targets of transmission lines that need to be photographed, truly realizes target-level quality evaluation, and can effectively ensure that the exposure of key equipment targets in captured images is normal and clear. It is in the center of the field of view, eliminating the influence of background and irrelevant areas on quality inspection.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an on-line inspection method for photographing quality of power transmission line equipment. Background technique [0002] The use of UAVs for transmission line inspections has become one of the mainstream operating methods for power grid inspection units. UAVs equipped with visible light pods to capture images of key equipment on transmission lines to determine whether defects occur are the main operating methods for UAV inspections. It greatly improves the efficiency of inspection operations and ensures the safe operation of lines. At present, the shooting of inspection images mostly depends on the experience of inspection personnel. The collected data often has problems such as underexposure, overexposure, blurred key equipment, and unreasonable shooting angles. However, frequent re-shooting, re-shooting and manual elimination of unqualified data during data proces...
