基于改进Deeplabv3+模型的农村道路提取方法研究

Research on rural road extraction method based on improved Deeplabv3+ model

  • 摘要: 从国产高分辨率影像中快速准确提取农村道路在信息管理、农村农业现代化等领域具有重要的价值,但由于背景噪音复杂、道路蜿蜒细长、易受阴影遮挡等,传统遥感解译方法提取农村道路信息效率低、精度不高. 文章针对农村道路的特征,对Deeplabv3+模型进行改进,设计了一种兼具效率和精度的高分辨率影像农村道路信息提取改进模型. 首先,使用Mobilenetv2作为模型的主干,减少模型的参数;其次,在ASPP模块中串联CBAM,加强模型的特征感受能力;最后,添加Dice Loss函数改进损失函数,克服样本的不均衡. 实验结果表明,细节的改进使得各项指标明显提升,效率和精度达到了最高;与经典模型相比,改进模型在MPA、MIoU上取得了更高的分数,虽然对深层特征的深度学习需要花费更多的时间,但改进模型在精度效率上均优于其他模型.

     

    Abstract: The rapid and accurate extraction of rural roads from domestic high-resolution images has important value in fields such as information management and modernization of agriculture and rural areas. However, traditional remote sensing interpretation methods have low efficiency and accuracy in extracting rural road information, due to the rural roads’ background being noisy, the roads being narrow, long and winding, and susceptible to shadow occlusion. In this research is improved the Deeplabv3+ model based on the characteristics of rural roads and is designed a high-resolution image rural road extraction model that is efficient and accurate. Firstly, Mobilenetv2 is used as the backbone of the model to reduce its parameters; secondly, Convolutional Block Attention Module (CBAM) is cascaded in the Atrous Spatial Pyramid Pooling (ASPP) module to enhance the model’s feature perception ability; and finally, Dice Loss function is added to improve the loss function and overcome the sample imbalance. The results show that the improvement of details has significantly improved various indicators, achieving the highest efficiency and accuracy. Compared with the classic model, the improved model has achieved higher scores in Mean Pixel Accuracy (MPA) and Mean Intersection over Union (MIoU). Although deep learning of deep features requires more time, the improved model can achieve higher efficiency and accuracy than other models.
