摘　　要：为利用遥感手段快速、精准提取宁夏贺兰山东麓酿酒葡萄种植信息,提出了一种基于深度迁移学习的酿酒葡萄种植信息提取方法。该方法以全卷积神经网络(Fully convolutional networks,FCN)为基础,利用高分二号卫星遥感资料,以地面采集样本数据进行网络模型训练,利用迁移学习方法将训练好的网络模型迁移到FCN网络模型中,对其进行初始化,避免过拟合问题的发生,其网络训练验证集准确率高达88.16%,较传统的基于深度学习方法准确率提高7.17个百分点。结果表明,基于深度迁移学习的贺兰山东麓酿酒葡萄种植信息提取检测准确率可达91.93%,检测召回率达到91.15%。In order to extract the wine grape planting information of the eastern foot of Helan mountain by using remote sensing,a method based on deep transfer learning was proposed.On the basis of fully convolutional network(FCN),this method used the GF-2 remote sensing data to collect the sample data for the information extraction training.The trained network model was transferred to the FCN model by using the transfer learnin method.It was initialized in the network model to avoid over-fitting problem.The accuracy rate of its network training validation set was as high as 88.16%,which was 7.17 percentage points higher than that of traditional deep learning methods.The results showed that the accuracy rate of wine grape planting information extraction based on deep transfer learning at the eastern foot of Helan Mountain could reach 91.93%,and the recall rate reached 91.15%.
