    摘要:

    针对遥感图像因雨雪雾等恶劣天气造成目标难以检测和检测性能下降等问题,研究一种以YOLOv11为基本架构,融合图像增强的遥感目标检测模型。首先,基于GFFA去雾网络,创建图像细节增强模块以弱化退化特征对检测任务的影响,并与检测网络集成为端到端的网络架构,以提升目标检测性能;同时,在YOLOv11主干网络中引入高效双层聚合网络模块模块取代原C3k2模块,通过双重卷积技术,提升特征表征能力,解决计算消耗过度问题;在此基础上,构建感受野双注意力卷积模块取代原Conv模块,利用感受野扩展特征,抑制背景噪声,从而提高目标检测精度。三者依次协同作用,首先提高输入图像质量,进而优化特征表征能力,随之进行深层特征降噪以精炼输出。最后,利用恶劣天气真实数据集和合成数据集进行实验,结果表明,改进模型的平均精度均值(mAP)mAP@0.5值较原模型提升2.4%和2.3%;mAP@0.5:0.95值较原模型提升4%和1.3%,验证了所提方法的有效性和可行性。

    Abstract:

    To address the challenges of difficult target detection and degraded detection performance in remote sensing images caused by adverse weather conditions such as rain, snow, and fog, this study proposes a remote sensing target detection model integrated with image enhancement, namely you only look once-image detail enhancement (YOLO-IDE), based on the YOLOv11 architecture. Firstly, inspired by the GFFA dehazing network, an image detail enhancement (IDE) module is designed to mitigate the impact of degraded features on the detection task. The enhancement module is integrated with the detection network into an end-to-end architecture to improve target detection performance. Meanwhile, the original C3k2 module in the YOLOv11 backbone is replaced with the CSP efficient dual layer aggregation networks (CSP-EDLAN) module. By adopting dual convolution techniques, the proposed module enhances feature representation while alleviating excessive computational consumption. Furthermore, the original Conv module is replaced with a receptive field dual attention convolution (RFDAConv) module, which expands the receptive field to suppress background noise and thereby improve target detection accuracy. The three components function in sequential coordination, first improving the quality of input images, then optimizing feature representation capability, and finally denoising deep-level features to refine outputs. Finally, experiments are conducted on both real-world and synthetic datasets under adverse weather conditions. The results show that, compared with the baseline YOLOv11 model, the proposed model achieves improvements of 2.4% and 2.3% in mAP@0.5, as well as 4% and 1.3% in mAP@0.5:0.95, respectively. These results verify the effectiveness and feasibility of the proposed method.
