Improved SIFT (Scale Invariant Feature Transform)-based electric power inspection field operation equipment image recognition method and device and storage medium

The invention relates to an image identification method and device for electric power inspection field operation equipment in electric power application, and a storage medium. The method comprises the following steps: acquiring an electrical equipment image, establishing an electrical equipment image data set, and performing preprocessing; accurate detection of key points of an image recognition object is carried out on the preprocessed image; performing feature extraction and description on the power equipment image based on an SIFT algorithm, establishing association point information and an index of the association point information and a power equipment category, establishing a power equipment feature value, extracting feature points and storing the feature points in a feature library; performing accurate identification and analysis on each part of the distribution network equipment in the electric power inspection image by using the identification service capability provided by the computing center; and
