The application provides a lightweight multi-scale
remote sensing image rotating target detection method and
system, aiming at the problem that the target and background in the
remote sensing image are more complex, based on a YOLOv4 model, shallow feature information is added in a
feature fusion network; in order to alleviate the problem of feature loss caused by too many network
layers, a weighted bidirectional feature
pyramid is used as the
feature fusion network; in order to improve the
receptive field of the feature, a multi-scale hollow
convolution module is added after the
feature fusion, so as to improve the detection precision; the
remote sensing image rotating target detection, the long side representation method represents the angle parameter, the annular
smoothing label of the
Gaussian function is used to convert the angle parameter from the regression problem to the classification problem, and the loss problem caused by the angle periodicity is reduced; a depth separable
convolution and a global attention module are used to design a lightweight module, and the traditional
convolution is replaced in the detection model, so that the model is lightweight.
