Substation multi-pointer instrument identification method and device based on multiple tasks

The invention relates to the technical field of machine identification, in particular to a transformer substation multi-pointer instrument identification method and device based on multiple tasks. The invention provides an efficient multi-task instrument identification network, the network can process three key tasks of target detection, instrument circle center and pointer segmentation of the transformer substation instrument at the same time, and the detection precision of the instrument pointer is greatly improved while the detection speed is improved. The algorithm provided by the invention has higher universality, realizes the recognition of various instruments and various pointers, and effectively solves the problem that one instrument has one recognition algorithm. According to the method, all data sets come from an actual transformer substation, under the conditions of an outdoor scene and poor image quality, accurate identification of single-needle and double-needle instruments such as an instrument,
