Embodiment Construction
[0037] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] The present invention is based on the size-balanced FCOS high-resolution remote sensing scene target detection method, comprising the following steps:
[0039] (1) In the size-balanced FCOS training phase, the centrality and GIoU of the RoI are obtained.
[0040] FCOS extracts features through the backbone network, and then uses the feature pyramid network to assign targets of different scales to different pyramid network layers for downsampling; the target detection module of FCOS regresses the features of each layer pixel by pixel, and screens out the target anchor boxes For the positive samples in the model, the regression probability, centrality, and distance between the positive sample coordinates and the four sides of the target anchor box ar...
