Unmanned aerial vehicle target automatic search method and device based on attention mechanism

The invention discloses an unmanned aerial vehicle target automatic search method and device based on an attention mechanism, and belongs to the field of computer vision and image processing, and the method is used for automatic search of a specific target of unmanned aerial vehicle aerial photography data and comprises the steps of preprocessing a real-time aerial photography image, designing a Soft Attention module, improving a measurement loss function, and carrying out automatic search. The selection of the sample pair of the function is to carry out joint training on samples difficult to mine in class centers to realize the unmanned aerial vehicle target automatic search method based on Multi-stage Attention and Center Triplet Loss, and the Multi-stage Attention structure solves the problem of carrying out feature matching under the condition of not additionally increasing the calculation amount. And secondly, improving a triple loss and center loss function, so that the selection of the sample pair is n
