Abstract

The invention relates to a power transmission corridor foreign matter detection method and system based on a twin network, and belongs to the technical field of remote sensing. The method comprises the following steps: firstly, acquiring a multi-temporal remote sensing satellite image of a power transmission corridor, carrying out artificial fine labeling on a change target and a region in the multi-temporal image, then slicing and binarizing the labeled region, then training a training set containing foreign matters in the power transmission corridor by using a twin network, obtaining a modelcapable of detecting the foreign matters in the power transmission corridor, and then detecting the multi-temporal remote sensing satellite image of whether the foreign matters exist in the power transmission corridor or not by using the obtained model to judge whether the foreign matters exist in the power transmission corridor or not. The method can detect and identify various power transmission corridor foreign matters, has calculation efficiency significantly superior to that of a manual method, has higher foreign matter detection accuracy and reliability, and provides convenience for operation and maintenance of a power transmission line.

Description

technical field [0001] The invention belongs to the technical field of remote sensing, and specifically relates to a method and system for detecting foreign matter in a power transmission corridor based on a twin network, which is used for detecting changes in multi-temporal remote sensing satellite images of the power transmission corridor, and then discovering foreign matter in the power transmission corridor. Background technique [0002] Foreign object detection in power transmission corridors involves operations such as ground object recognition and multi-temporal change analysis in remote sensing image scenes, and is closely related to ground object detection and change detection technologies. The foreign object detection method based on ground object recognition relies on a ground feature extraction model with high enough recognition accuracy for the multi-temporal image scene to be detected. Changes in appearance, shape, and position are analyzed to obtain targets th...
