Anchor-frame-free infrared ship multi-target video tracking method and system based on twin network

The invention discloses an anchor-frame-free infrared ship multi-target video tracking method and system based on a twin network, and the method comprises the steps: inputting two adjacent frames of images into two branches of the twin network, and generating a multi-scale feature map; then inputting into a hierarchical decoupling network, and generating a multi-scale feature map used for a detection task and a multi-scale feature map used for an identity re-recognition task; inputting a feature reconstruction network, and generating a feature map for a detection task and a feature map for an identity re-recognition task; inputting into an identity re-identification network to generate a target identity embedding vector; dividing an infrared multi-target tracking data set into a training set and a test set, and sequentially inputting the training set into a twin network, a hierarchical decoupling network, a feature reconstruction network and an identity re-recognition network for training and learning to obta
