The setup uses an Orin AGX running NODAR AI and Hammerhead Viewer on saved playback data, with three stereo pairs (inner 35 mm, 25 mm, 16 mm; and an outer pair providing about a 30 degree horizontal field of view). In daytime, the reconstruction shows targets like an umbrella at 11 m, a chair at 19 m, and a far fence at 29 m, capturing wave propagation from a cannonball splash at 5 fps (played back at 10 fps). At night, only two 850 nm LED NIR illuminators were used at 10:20 pm (astronomical twilight), and the system still reconstructed the water surface, with a focus on how added visible floodlighting improves results. https://www.nodarsensor.com/use-cases/maritime Additional information: The stereo camera was mounted on the top of the staircase, located 3.4 meters high from the immediate ground below it.
