Autonomous acoustic remote sensing of underwater infrastructure is challenging due to the physical characteristics of 3D sonar and the geometric degeneracy commonly encountered in feature-poor underwater environments. Accurate localization is essential for integrating sequential sonar observations into globally consist...

Accurate localization and 3-D reconstruction are critical for unmanned surface vehicles (USVs) operating in dynamic marine environments. However, water surface reflections, global positioning system (GPS) interruptions, and motion disturbances caused by wind and waves significantly degrade LiDAR–inertial odometry (LIO)...

Side-scan sonar (SSS) mosaicking plays a crucial role in large-scale seabed mapping but is challenged by complex nonlinear, spatially varying distortions due to diverse sonar acquisition conditions. Existing rigid or affine registration methods fail to model such complex deformations, whereas traditional nonrigid techn...
