Application of image recognition technology in electrical equipment on-line monitoring

ZHANG Hao1,WANG Wei1,XU Li-jie1,QIN Huan2,LIU Ming3(1.School of Electrical Engineering,Beijing Jiaotong University,Beijing 100044,China;2.School of Electrical and Electronic Engineering,North China Electric Power University,Beijing 102206,China;3.Baishan Power Supply Corporation,Baishan 134300,China)  
In order to reduce the amount of calculation of the traditional matching algorithm which is based on grayscale,the shape characteristics of image analysis technology is used and a new template matching algorithm is proposed.The algorithm first checks out the following interlacing data and roughly matches them,and then does precise matching.Therefore,it can greatly reduce the mount of data calculation.The algorithm which is applied in the image recognition of power transformer has an advantage of speed of calculation,and it can more quickly confirm the position of the power transformer.This paper also points out the prospect of applying remote digital video monitoring and image recognition technology in power systems.
