Advances and Challenges in Multimodal Remote Sensing Image Registration

Over the past few decades, with rapid development of global aerospace and aerial remote sensing technology, types sensors have evolved from traditional monomodal (e.g., optical sensors) to new generation multimodal multispectral, hyperspectral, light detection ranging (LiDAR), synthetic aperture radar (SAR) sensors). These advanced devices can dynamically provide various abundant images (MRSIs) different spatial, temporal, spectral resolutions according application requirements. Since then, it is great scientific significance carry out research MRSI registration, which a crucial step for integrating complementary information among data making comprehensive observations analysis Earth’s surface. In this work, we will present our own contributions field image summarize advantages limitations existing registration methods, then discuss remaining challenges make forward-looking prospect future field.
