Abstract

The present invention provides a method and system for identifying fog levels of power transmission lines based on images. The method includes: collecting multiple training images of power transmission lines in sunny days, light fog, fog, heavy fog, dense fog, and strong dense fog; Described training image establishes the image class corresponding to sunny day, light fog, fog, heavy fog, thick fog, strong dense fog; feature; the feature of the image class is trained as the input data of Naive Bayesian, and the fog level recognition template library is obtained; the image to be identified of the collection transmission line; the feature corresponding to the image to be identified is extracted; according to the The fog level recognition template library recognizes the features corresponding to the image to be recognized to obtain a recognition result; and outputs the recognition result of the image to be recognized. According to the division of horizontal visibility distance, the fog level is divided into light fog, fog, heavy fog, dense fog, and strong dense fog, so as to realize the classification and recognition of the fog level.

Description

technical field [0001] The present invention relates to the technical field of power monitoring, in particular to the detection technology of transmission lines in power systems, and specifically to a method and system for identifying fog levels of transmission lines based on images. Background technique [0002] Foggy weather seriously threatens the safe operation of the power system. Foggy weather will pollute the transmission lines, causing fog flash and pollution flash to the transmission lines. Fog flash is due to the large amount of pollutants contained in the dense fog, which pollutes the wires and leads to a sharp increase in the conductivity of the foggy air, causing short circuits, tripping, tripping and other faults in the transmission line, resulting in large-scale power outages in the power grid. Fog flashes can shut down electric locomotives, factories, and people's lives. Pollution flashover refers to the pollution attached to the insulating surface of elect...
