Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] A method for identifying small components of a transmission line, comprising the following steps:

[0034] 1. Realize the detection of wires through the LSD algorithm

[0035] 1) if figure 1 , figure 2 As shown, the wire detection is performed by the LSD algorithm;

[0036] 2) Group the wires: Due to the characteristics of the wires of the transmission line, for the same direction, the positions close to each other are divided into a group to form a parallel wire group.

[0037] 2. Determine the position of small parts by searching along the direction of the wire

[0038] Under the condition of identifying the group of parallel wires, according to the perceived attachment, the wires are segmented to analyze their consistency, continuity, and width mutation areas, and then cluster these change areas to diagnose whether there are spacers, wire...

Abstract

The present invention discloses a transmission line small part identification method. The method comprises a step of using an LSD straight line detection algorithm to carry out conductive wire detection on a collected image, grouping the detected conductive wires according to the characteristics of transmission line conductive wires, and constructing a parallel conductive wire group, a step of dividing the conductive wire group into multiple wire segments, and searching the mutational sites in the wire segments, a step of using a sampling method to calculate the width change between sampling points, and calculating the length of the width change, a step of calculating the pixel gray value mean value in each conductive wire segment in the parallel conductive wire group, and obtaining the pixel gray value mean value of each wire segment, the absolute difference of the pixel gray value mean value and an adjacent segment gray value distance are calculated, a step of calculating each segment absolute gray value difference distance ratio in each parallel conductive wire and an adjacent segment gray value difference distance ratio, judging whether the ratios are larger than a set threshold or not, and confirming a small part if so.

Description

technical field [0001] The invention relates to a method for identifying small parts of a power transmission line. Background technique [0002] Transmission line conductors are susceptible to wind, natural disasters, etc. and various defects will appear. If they are not discovered and repaired in time, the transmission line will be damaged, resulting in large-scale power outages, resulting in immeasurable economic losses. [0003] Anti-vibration hammers, spacers and other equipment on the wires of the transmission line can effectively reduce the impact of wind on the wires, reduce the probability of "dancing" on the transmission line, and protect the safety of the tower. [0004] Aiming at the identification of small parts such as anti-vibration hammers and spacers, a method for locating transmission line spacers using video image processing technology (application number: 201310048522.4) proposes a transmission line spacer identification and positioning method using video ...
