High-voltage device image recognition method and device based on component type and component ratio

The invention provides a high-voltage device image recognition method and device based on a component type and a component ratio. The contours of components of an obtained image are extracted by usingan edge extraction method, the components comprise general components and decisive components, and a sample library is matched to complete preliminary classification. With the positional relationshipbetween equipment components as a characteristic, the correctness of the classification is further improved. According to characteristics that the positional relationships of the same type of equipment components are the same and the positional relationships of different equipment components are different, the types of the components and equipment with a small difference in appearance are distinguished, and the equipment classification is finally completed. According to the method and the device, the classification and identification of high-voltage equipment of a substation can be accuratelycompleted, and the recogni
