Detection method for small parts of electric energy meter

The invention discloses an electric energy meter widget detection method, and relates to the field of visual detection. At present, small target detection has a small detection effect on small parts of a standard electric meter, the detection time is long, and the detection precision is limited to be improved; according to the technical scheme, the target detection neural network is used for extracting part of the electric energy meter image from the original image to form the picture only containing the whole meter; calculating the length-width ratio of the electric energy meter picture, and setting the length and width of a standard electric energy meter; determining the number and types of electric energy meter components and coordinates of the upper left corner and the lower right corner of each component; setting a coordinate initial value, clustering the plurality of electric energy meter pictures by using a K-means clustering method, determining a coordinate center value of each component, and forming
