Modeling, Identification, and Control of an Unmanned Surface Vehicle [PDF]
Journal of Field Robotics, 2013 This paper describes planar motion modeling for an unmanned surface vehicle (USV), including a comparative evaluation of several experimentally identified models over a wide range of speeds and planing conditions. The modeling and identification objective is to determine a model that is sufficiently rich to enable effective model‐based control design ...

Proposed Efficient Design for Unmanned Surface Vehicles
CoRR, 2020 Recently worldwide interest is growing toward commercial, military or scientific Unmanned Surface Vehicle (USV) and hence there is required to develop their guidance, navigation, and control (GNC) systems. Real USVs are a relatively new advent, so the drawbacks of each model will be modified during the time.

Unmanned Aerial Vehicle Surveying For Monitoring Road Construction Earthworks
The Baltic Journal of Road and Bridge Engineering, 2019 Unmanned aerial vehicle photogrammetry is a surveying technique that enables generating point clouds, 3D surface models and orthophoto mosaics. These are based on photos captured with a camera placed on an unmanned aerial vehicle. Within the framework of

Path‐following algorithms and experiments for an unmanned surface vehicle [PDF]
Journal of Field Robotics, 2009 AbstractThis paper addresses the problem of path following in two‐dimensional space for underactuated unmanned surface vehicles (USVs), defining a set of guidance laws at the kinematic level. The proposed nonlinear Lyapunov‐based control law yields convergence of the path‐following error coordinates to zero.

Control of an Unmanned Surface Vehicle With Uncertain Displacement and Drag [PDF]
IEEE Journal of Oceanic Engineering, 2017 Experimental testing of an unmanned surface vehicle (USV) has been performed to evaluate the performance of two low-level controllers when displacement and drag properties are time-varying and uncertain. The USV is a 4.3 meter long, 150 kilogram wave adaptive modular vessel (WAM-V) with an inflatable twin hull configuration and waterjet propulsion ...

BINOCULAR VISUAL ENVIRONMENT PERCEPTION TECHNOLOGY FOR UNMANNED SURFACE VEHICLE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Binocular vision system is an essential way for target localization in many fields, which has been widely used as payload of unmanned surface vehicles (USV). High resolution cameras, which can provide richer information, are utilized more often on a USV.
