MBACA-YOLO: A High-Precision Underwater Target Detection Algorithm for Unmanned Underwater Vehicles

Machines
This paper addresses the issue of low detection accuracy in underwater optical images for unmanned underwater vehicles (UUVs) during practical operations, caused by factors such as uneven lighting, blur, complex backgrounds, and target occlusion.

Eliciting expert judgement for the probability of AUV loss in contrasting operational environments [PDF]

, 2007
Each time an autonomous underwater vehicle (AUV) is used in the sea there is a non-zero probability of loss. Quantifying probability of loss is not an exact science; therefore much depends on the fault history of the vehicle, the operational environment ...

Geometric bounding techniques for underwater localisation using range-only sensors

This paper describes the application of geometric bounding techniques to range-only navigation of an underwater vehicle. A geometric technique is defined to obtain a position fix of an underwater vehicle using a combination of dead-reckoning navigation ...

Trajectory Planning for Autonomous Underwater Vehicles in Uneven Environments: A Survey of Coverage and Sensor Data Collection Methods

Future Internet
Autonomous Underwater Vehicles (AUVs) play a central role in marine observation, inspection, and monitoring missions, where effective trajectory planning is essential for ensuring safe operation, reliable sensing, and efficient data transfer.

A Nature inspired guidance system for unmanned autonomous vehicles employed in a search role.

Since the very earliest days of the human race, people have been studying animal behaviours. In those early times, being able to predict animal behaviour gave hunters the advantages required for success. Then, as societies began to develop this gave way,
