Researchers have developed DA-NBV, a novel direction-aware next-best-view planning policy designed to improve the efficiency and completeness of 3D reconstructions for ships at sea. This new approach augments traditional occupancy modeling with directional observation statistics, utilizing a learnable Position Advantage Field (PAF) to guide viewpoint selection. DA-NBV also incorporates a locally constrained action space and a nonlinear coverage-shaping reward to enhance scanning efficiency, particularly in challenging maritime conditions with wave-induced motion and wind disturbances. Experiments demonstrate that DA-NBV leads to more complete reconstructions and reduced Chamfer distance, while also improving path efficiency. AI
