Abstract: A robust registration method with bidirectional consistent transformation is proposed to solve the problem of multi-source remote sensing image relatively poor registration effect due to large nonlinear radiation and geometric distortion. First, the fine-tuned ResNet101 network model was utilized to extract images learning features. To improve the reliability of the corresponding feature matching, we designed a bidirectional consistency feature matching model in the feature matching stage. Then, robust registration was achieved by using a parametric regression transformation model with weight based on a small lightweight network. In our experiments, we tested the proposed algorithm using Google Earth images, satellite images, UAV images and Google Earth-satellite-UAV images, and compared it with the several typical methods. The results show that the proposed method has advantages in the accuracy, efficiency and robustness, and achieves automatic registration accuracy almost within 2 pixels.
