摘　　要：从高分辨率遥感影像中提取并检测路网一直都是计算机视觉研究的热点和难点。目前,基于深度学习的遥感影像路网检测方法大部分都是以卷积运算为基础的卷积神经网络,而以深度可分离卷积运算为基础深度可分离卷积神经网络作为以卷积运算为基础的卷积神经网络的替代神经网络,不仅在特征提取能力上优于卷积神经网络,而且在参数量和计算量方面也低于卷积神经网络。鉴于此,该文利用深度可分离卷积运算替换卷积运算,并引入残差模块,构造了深度可分离残差网络进行遥感影像的路网自动检测的应用。实验结果表明,在RRSI和CHN6-CUG数据集上,虽然深度可分离残差网络的准确率和损失与相对应的卷积神经网络和残差网络的准确率和损失的区别不大,但是深度可分离残差网络的训练耗时时长远远低于相对应的卷积神经网络和残差网络的训练耗时时长,而且深度可分离残差网络的路网检测实际结果也优于相对应的卷积神经网络和残差网络的路网检测实际结果。Extracting and detecting road network consistency from high resolution remote sensing images has been a hotspot and difficulty in computer vision research.At present,the existing network remote sensing image detection method based on deep learning is mostly based on the convolutional operation and convolutional neural network.As an alternative neural network to convolutional neural network,deep separable convolutional neural network based on the deep separable convolutional operation is not only superior to convolutional neural network in feature extraction ability,but also superior to convolutional neural network in parameter amount and calculation amount.In view of this,we use the deep separable convolutional operation to replace the convolutional operation,and introducing the residual module,construct a deep separable residual network to detect road network automatically of remote sensing images.The experimental results show that on RRSI and CHN6-CUG datasets,although the accuracy and loss of the deep separable residual network is not significantly different from those of the corresponding convolutional neural network and residual network,the training time of the deep separable residual network is much longer than that of the corresponding convolutional neural network and residual network.Moreover,the actual results of the road network detection of the deep separable residual network are also better than those of the corresponding convolutional neural network and residual network.
