Water Target Recognition Method and Application for Unmanned Surface Vessels [PDF]
IEEE Access, 2022 Water target recognition is a critical challenge for the perception technology of unmanned surface vessels (USVs). In the application of USV, detection accuracy and the inference time both matter, while it is tough to strike a balance and single-frame water target detection behaves unstable in the video detection.

Methods for ensuring the navigation safety of unmanned surface vessel
Technology audit and production reserves, 2019 When creating unmanned surface vehicles (USV), special attention is paid to the safety of navigation. One of the main threats at sea is the threat of collision. Two main directions of ensuring the safety of navigation can be distinguished. The first is legal regulation and a number of international documents that are binding on all ship-owners.
