Researchers have developed a new method for underwater robots to improve their perception capabilities under degraded visual conditions by fusing visual data with sonar information. This approach utilizes frozen DINOv2 foundation model representations for visual encoding and adapts a fusion mechanism to dynamically adjust the reliance on each modality based on visual reliability. The degradation-aware fusion method achieved a 33.5% relative improvement in balanced accuracy under extreme degradation compared to the DINOv2 baseline alone, demonstrating the value of adaptive cross-modal fusion for robust underwater robotic perception.
