Dangerous area personnel monitoring method, equipment and medium

The embodiment of the invention provides a dangerous area personnel monitoring method and device and a medium, and the method comprises the steps: obtaining low-level features and high-level features according to a training set of an RGB image and a thermal imaging image, carrying out the operation of decoupling multi-scale feature interaction into intra-scale feature interaction on the high-level features, and obtaining decoupling features; performing cross-scale fusion operation on the low-level features and the decoupling features to obtain fusion features; selecting a fusion feature of which the classification score and the intersection-union ratio score exceed a preset threshold value as a target feature; performing weighted summation on the target features according to the attention weight, and performing nonlinear transformation on a weighted sum value to obtain a prediction result; adjusting parameters of a detection model according to a prediction result to obtain the detection model, and performing
