A foreign matter identification method for laser foreign matter remover

Abstract

A foreign matter recognition method for a laser foreign matter remover, comprising the steps of: ① collecting an image of a transmission line through a laser foreign matter remover; ② performing image segmentation on the collected image by using the maximum inter-class variance method; ③ performing image segmentation on the segmented image Morphological processing to obtain the filtered image; ④ Edge detection on the filtered image to obtain an edge extraction image; ⑤ Calculate the curvature of each edge point; ⑥ According to the distribution of edge curvature, determine whether there are abnormal points in the edge curvature; The point coordinates and the distance measuring system of the laser foreign object remover can obtain the three-dimensional coordinates of the intersection point of the foreign object and the wire. The invention determines the intersection position of the foreign matter and the wire by identifying the foreign matter, and then controls the emission direction of the laser emitter, realizes the automatic removal function of the foreign matter, realizes the automatic operation of the laser foreign matter removal equipment, improves the work efficiency, and satisfies the automation and intelligence in the field of power grid maintenance development needs.

Description

technical field [0001] The invention relates to a graphic processing method, in particular to a foreign matter identification method used in a laser foreign matter remover, and belongs to the technical field of power grid maintenance. Background technique [0002] Transmission line network is the main carrier of power transmission. In recent years, foreign objects such as balloons, advertising banners, kites, agricultural plastic films, sunshade nets, Kongming lanterns, etc. have often entangled wires, causing phase-to-phase short circuits, which can lead to power outages in severe cases, and even cause personal injury and equipment failure. Most lines are located in places with complex terrain and harsh environments, so maintaining the normal operation of transmission lines is particularly important and arduous. [0003] The removal methods of foreign matter in the power grid include manual live-line operation on the tower, unmanned aerial vehicle spraying fire operation, ...
