Intelligent Interpretation of High-resolution Remote Sensing Images based on Deep Learning

Abstract

As an important task of intelligent interpretation research, the object detection of remote sensing images still has many problems to be solved. In this paper, aiming at the characteristics of small-sized object and complex background, in order to solve the problem of poor effect of existing object detection algorithms when applied to remote sensing images, an object detection model of remote sensing images based on the improved Faster R-CNN model is proposed. Based on the original Faster R-CNN model, the feature extraction network VGG16 is improved by designing a feature fusion module. In order to verify the effectiveness of the model in this paper, it is used to carry out experiments on NWPU VHR-10 and DOTA datasets, and mAP has reached 0.886 and 0.810 respectively, which was 6.9% and 11.6% higher than the original Faster R-CNN. The experimental results show that our method effectively improves the object detection effect of remote sensing images, and achieves good results in remote sensing images with small-sized object and complex background.
