Embodiment 1

[0159] A method for identifying a sliding block circuit breaker based on an inspection robot, comprising the following steps:

[0160] Step 1. For each inspection point, select an image in the center of the circuit breaker taken at the inspection point as a template image, such as figure 2 As shown, the SVM multi-classifier is trained by using the image data set of the slider circuit breaker collected in advance;

[0161] Step 1-1. Prepare the training sample set, specifically:

[0162] (1) Collect 100,000 pictures containing slider circuit breakers, use the pictures in the energy storage state as the positive sample set, and use the pictures in the non-energy storage state as the negative sample set;

[0163] (2) Crop the picture, delete the redundant information outside the slider display window area on the slider circuit breaker

[0164] (3) Scale the picture into a rectangle with a length and a width of 48 pixels;

[0165] Step 1-2, extracting the HOG features of posit...

Abstract

The invention provides a method for identifying a slider circuit breaker based on a patrol robot. The invention is mainly divided into five steps: (1) training SVM multi-classifier by using image dataset; 2) that patrol robot arrives at the designate patrol point to obtain the pictures to be detected; 3) carry out coarse positioning and precise position on that target area, and screening the candidate area of the target to obtain a slider circuit break; 4) carry out image preprocessing on that acquire slider-type circuit breaker to extract two regions with the largest connecte area; (5) HOG features of two connected regions are extracted respectively and sent to SVM multi-classifier to get the final recognition results. As that machine learn is utilized, the detection and identification task of the slide circuit breaker can be effectively completed under different illumination and posture conditions, the automation level and the accuracy rate of the image identification unde the complex environment are improved, and the problems of missing detection and false detection are reduced to the maximum extent.

Description

technical field [0001] The invention relates to target detection technology, in particular to a method for identifying a sliding block circuit breaker based on an inspection robot. Background technique [0002] The electric power industry is closely related to people's life, and the slider circuit breaker in the substation is the most basic device in the electric power industry, which is crucial to the power supply. In recent years, the detection and identification of slider circuit breakers are not in place, which leads to the phenomenon that the normal transmission of electricity occurs from time to time, causing huge economic losses to people's lives and industrial production. [0003] At present, there are mainly two types of detection methods for circuit breakers. The first is the manual inspection method. However, because most of the circuit breakers in substations exist in the field, the staff are generally far away, and when problems occur, they cannot be solved in ...
