Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Typical instrument panels on substation equipment include barometers, oil temperature gauges, temperature gauges, arrester gauges, desktop digital display instruments related to the analysis of the purity of sulfur hexafluoride gas used in electrical equipment, LED warning lights, and TFT display screens. Among them, the barometer, oil temperature gauge, temperature gauge and arrester gauge are pointer instruments, and the readings are reflected by the scale pointed by the pointer. The LED alarm light is used to indicate the alarm information of the equipment, and its position can be distributed on the dial of the barometer, the oil temperature gauge or the LED display area. The content displayed on the TFT screen is complex, including equipment status information, alarm information, multimedia information, etc., and the form of information display includes icon...

Abstract

The invention relates to a method for recognizing electric symbols of a target object area by adopting a template matching method in electric power monitoring, belonging to the field of image recognition. Includes such steps as preprocessing the image, primitive recognition of the preprocessed image, template matching method to identify the electrical standard symbols in the target object region for the electrical standard pattern with the same electrical pattern shape, and obtaining a judgment result; according to the judgment result, obtaining a recognition result of a running state of the equipment or a position of the equipment. Then the judgment result is displayed and the recognition result is returned. It uses template matching and contour extraction to extract the target region accurately, and classifies and summarizes the similar or similar scenes and phenomena. It is feasible to accurately recognize the color, outline and content of electrical symbols, and the transformationfrom manual inspection to machine inspection is realized. The invention can be widely used in the automatic collection and analysis of monitoring images of substations and in the operation and management of substation equipments.

Description

technical field [0001] The invention belongs to the field of image recognition, in particular to a method for extracting image features or characteristics used to recognize graphics. Background technique [0002] Based on considerations of reducing operating costs and saving floor space, as unattended substations are increasingly used, various video surveillance systems are widely used. [0003] Since video surveillance will produce a large number of live video or photo images, image processing, interpretation, or identification and judgment based on the pictures shown have become necessary in the operation and monitoring of power systems. [0004] "Visual understanding" technology is an intelligent system that can independently observe and analyze the environment through the visual system (camera). It is an important direction for the development of artificial intelligence technology and machine vision technology. Inspection, remote centralized monitoring, video image big ...
