N2 - Korean multi-purpose satellite 3A (KOMPSAT-3A) can acquire electric optical (EO) and mid-wave infrared (MIR) images. Since MIR and EO images provide different information, they can be used together to effectively observe various phenomena on the Earth's surface. However, geometric misalignments exist between the EO and MIR images as the difference in the positions of each sensor when acquiring the images. In this study, we propose a hybrid pyramid matching (HPM) method to conduct the image registration between heterogeneous EO and MIR images with different spatial and spectral characteristics. The HPM method extracts reliable tie points (TPs) by iteratively adjusting the location of local templates in pyramid image pairs. Then, the image registration is conducted using transformation matrix estimated based on the TPs. The HPM method achieved superior accuracy and performance at three different sites.
