An improved model based on you only look once version 8(YOLOv8) is proposed to solve the problem of low detection accuracy due to the diversity of object sizes in optical remote sensing images. Firstly, the feature pyramid network(FPN) structure of the original YOLOv8 mode is replaced by the generalized-FPN(GFPN) structure in GiraffeDet to realize the "cross-layer" and "cross-scale" adaptive feature fusion, to enrich the semantic information and spatial information on the feature map to improve the target detection ability of the model.
