摘要: 针对当前多数深度学习模型只能对高分辨率遥感影像裁剪图片进行土地利用类型判别的问题,结合VGGNet与Mask R-CNN开展了智能化建设用地目标检测研究。在建立研究区4类土地利用类型遥感影像数据集的基础上,对比了VGGNet、ResNet和DenseNet 3种卷积神经网络模型的分类精度,选取分类效果最优的神经网络模型VGGNet与Mask R-CNN实现建设用地目标检测智能化。结果表明:①VGGNet、ResNet和DenseNet 3种卷积神经网络模型的分类精度分别为:97.44%、93.75%和95.13%,且VGG16模型迭代次数最少,训练时间相对较少;②Mask R-CNN阈值设置对目标检测精度有重要的影响,当阈值设定为0.3时,VGG16结合Mask R-CNN的联合模型对建设用地检测的标定框精度最高。同时联合模型比单一使用Mask R-CNN模型对建设用地检测有更高的准确率,并且表现出了更强的适应性和鲁棒性。 关键词: 卷积神经网络(CNN);  目标检测;  影像分类;  高分辨率遥感影像;  建设用地     Abstract: To address the problem that most current deep learning models can only discriminate land use types for cropped images of high-resolution remote sensing images, this paper combines VGGNet and Mask R-CNN to carry out a study on intelligent construction land target detection. On the basis of establishing remote sensing image datasets of four types of land use types in the study area, we compare the classification accuracy of three convolutional neural network models, VGGNet, ResNet and DenseNet, and select the neural network model with the best classification effect, VGGNet and Mask R-CNN, to achieve intelligent construction land target detection. The results show that: (1) the classification accuracies of the three convolutional neural network models VGGNet, ResNet and DenseNet are 97.44%, 93.75% and 95.13%, respectively, and the VGG16 model has the least number of iterations and relatively less training time; (2) the Mask R-CNN threshold setting has an important influence on the target detection accuracy, when the threshold is set to is 0.3, the joint model of VGG16 combined with Mask R-CNN has the highest calibration frame accuracy for construction land detection. Also the joint model has higher accuracy than the single use of Mask R-CNN model for construction land detection, and shows more adaptability and robustness.
