Problems solved by technology

[0004] The purpose of the present invention is to propose a pointer-type circuit breaker identification method based on inspection robots, which solves the problems in the existing pointer-type circuit breaker detection and identification technology that the robot's position is not fixed, the target scale and angle change greatly, and the target is exposed to light. The problem of inaccurate detection and identification due to large impact

Embodiment 1

[0160] A method for identifying a pointer circuit breaker based on an inspection robot, comprising the following steps:

[0161] 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 using the pointer circuit breaker image data set collected in advance;

[0162] Step 1-1. Prepare the training sample set, specifically:

[0163] (1) Collect 100,000 pictures containing pointer circuit breakers, use the pictures in the open state as the positive sample set, and the pictures in the off state as the negative sample set;

[0164] (2) Crop the picture and delete the redundant information outside the circle of the pointer circuit breaker;

[0165] (3) Scale the picture into a rectangle with a length and a width of 48 pixels;

[0166] Step 1-2, extracting the HOG features of positive and negative samples, specifically:

[0167] (1) Conv...

Abstract

The invention provides a pointer circuit breaker identification method based on patrol inspection robot. The invention is mainly divided into five steps: (1) training SVM multi-classifier by using image data set; 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 target candidate area to obtain a pointer circuit breaker; 4) carry out image preprocessing on that acquire pointer circuit breaker, extracting a region with the largest connecte area, and detecting the upper and lower circular regions by using the Hough transform; (5) HOG features of circular region are extracted and sent to SVM multi-classifier to get the final recognition result. The invention utilizes machine learning, can effectively complete the detection and identification task of the pointer circuit breaker under different illumination and posture conditions, improves the automationlevel and the accuracy rate of the image identification under the complex environment, and minimizes the problems of missed detection and false detection.

Description

technical field [0001] The invention relates to target detection technology, in particular to a pointer type circuit breaker recognition method based on a patrol robot. Background technique [0002] The power industry is closely related to people's lives. The pointer circuit breaker in the substation is the most basic device in the power industry, and it is very important to the power supply. In recent years, the detection and identification of pointer 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 the phenomenon of improper switching and closing cannot be solved in ...
