The accurately and efficiently extracting rural settlements from high resolution remote sensing image is of important significance for rural government management. Due to the complex environment in rural region, the traditional supervised classification methods already could not satisfy the application requirements for automatically extracting rural settlements, and they can only obtain the results of low precision and incomplete extraction. In recent years, with the rapid development of deep learning in computer vision, the deep learning method has been widely used to target extraction based on high resolution remote sensing imagery. So, this paper proposed a rural settlements extraction method based on the deep learning using high-resolution remote sensing image. The Tensorflow deep learning framework was built up to train the Faster regional recommendation convolutional neural network model(Faster R-CNN). Image feature maps were extracted by the Convolutional Neural Network(CNN) firstly. The region proposal network (RPN) was built to extract the regions that might contain rural settlements. And the region was identified and classified by detection network. The method was tested and verified in the homemade datasets. This paper selected a typical area for testing. The experimental results show that the proposed method can extract the rural settlements areas with higher accuracy compared with traditional rural extraction ways.
