FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets
Journal of Field Robotics, EarlyView.ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...
