The invention belongs to the field of power system automation, and discloses an image retrieval method, system and device based on a triangular inequality and a storage medium, and the method comprises the steps: obtaining a clue image, extracting a visual feature vector of the clue image, and obtaining a clue visual feature vector; obtaining a cluster set with a first preset number higher than the clue visual feature vector similarity in a plurality of preset clusters, and obtaining a first preset number of similar cluster sets; through a triangular inequality judgment method and a preset distance calculation method, obtaining visual feature vectors with the similarity higher than the clue visual feature vector by a second preset number in all the visual feature vectors in all the similar clustering sets, and obtaining similar visual feature vectors with the second preset number; obtaining images corresponding to the similar visual feature vectors, and obtaining a retrieval result. According to the image retrieval method based on the triangular inequality, the defect that the retrieval efficiency is low during image retrieval of the power equipment is overcome, and the retrieval time consumption is greatly reduced.
Description
technical field [0001] The invention belongs to the field of electric power system automation, and relates to an image retrieval method, system, equipment and storage medium based on triangle inequality. Background technique [0002] As far as various information carriers are concerned, images can have a clear effect. In recent years, the electric power department has adopted a management method of taking digital images of equipment to record equipment information in terms of power equipment management. The use of equipment images mainly includes: 1. Distinguish equipment types from digital images; 2. Use before and after comparison, Managers often have to compare historical images of the same equipment with current images to observe changes in the paint surface. 3. From the additional information of the image, the parameters such as the device model, the location of the device and the service life of the device are known. [0003] Initially, these images were stored in th...
