Abstract

An image recognition method for substation switch opening and closing state based on the lack of disconnected image samples. By detecting the salient area of ​​the source image, the salient area and the non-salient area are separated, and the NSST algorithm is used to complete the fusion of the visible light image and the infrared image; the improved The SURF algorithm extracts the target feature quantity from the fusion image, and accurately locates the switch image area; uses the multi-threshold image segmentation method based on the chaotic cuckoo algorithm to process the image, and separates the target image from the background image; the image is obtained based on the Hough transform The slope of the straight line where the middle switch arm and the two contacts are located, and calculate the angle difference between the two, so as to judge the opening and closing state of the switch. The invention can fully integrate the effective information of the infrared image and the visible light image, realize the accurate identification of the switch state through the angle difference between the switch arm and the line where the switch contact is located, and can realize the switch state of the substation in the absence of disconnected sample images and low visibility Remote online monitoring.

Description

technical field [0001] The invention relates to the monitoring field of power equipment, in particular to an image recognition method for switching on and off states of a substation switch based on the lack of disconnected image samples. Background technique [0002] With the advancement of the intelligentization of substations, the remote monitoring and control of power equipment has become a reality. The construction of the image monitoring system has realized the "remote viewing" of various important monitoring information. In addition, the development and application of key technologies of image recognition provide strong technical support for real-time monitoring of substation-related equipment status information. [0003] The traditional remote identification of substation switches is based on image samples of two different states of split and combined, and the switch state is discriminated by feature matching according to the images captured on site. If the matching ...
