Method and device for estimating enemy power situation based on rotating target detection

The invention discloses an enemy force situation estimation method and device based on rotating target detection, and belongs to the field of computer vision and image processing, and the estimation method is used for situation estimation of enemy force structures and action directions. Rotating a target rectangular frame to increase a head position point, further carrying out preprocessing such as scale normalization and network structure design on the aerial image, designing a RoI Transform-based network structure based on the aerial image, and using a smooth loss function to obtain an aerial image model; bN regularization is added in front of a full connection layer to form BNNeck, situation estimation is carried out on the real-time air combat situation according to detected target types, number and direction information, the problem that direction prediction cannot be well carried out in an existing rotating target detection technology is solved, meanwhile, classification loss and measurement loss combin
