Automatic image registration of multi-modal urban remote sensing images remains a critical challenging task in remote sensing image analysis due to significant nonlinear radiation distortions between multi-modal image pairs, most of the traditional methods focus on the feature point detection and its local description and ignore the robust road information in multi-modal urban remote sensing images. Motivated by this, we propose a fast and robust registration method for multi-modal urban remote

The proposed method obtains three main stages: road lines extraction from images, intersection triangular feature construction, and triangular feature matching. The qualitative and quantitative experimental results show that the proposed method significantly outperforms other state-of-the-art methods, even when others completely fail to achieve the registration task of cross-modal images, our method still maintains good robustness and matching efficiency.
