DOI: 10.1109/jsen.2025.3592985
Abstract: Underwater terrain image matching provides a new approach for underwater vehicle terrain-matching localization. Underwater terrain images are usually generated by the projection of elevation values measured by acoustic bathymetry sensors. Due to the special characteristics… read more here.

DOI: 10.1109/lgrs.2023.3243938
Abstract: Underwater terrain image (UTI) matching provides a new idea for terrain-aided localization technology. However, the diversity of UTIs makes it very difficult to accurately match real-time terrain images (RTTIs) with reference terrain images (RTIs). To… read more here.
