The use of camera and LiDAR sensors to sense the environment has gained increasing
popularity in robotics. Individual sensors, such as cameras and LiDARs, fail to meet the …

LBL (Long Basic Line) positioning is an important and high-precision method for underwater
vehicle navigation. Due to its narrow work frequency-band, system would be easily affected …

As part of the research focusing on the safety of vessels during the lockage in navigation
locks, two different 1D numerical modeling approaches were tested. These approaches are …

This paper proposes an underwater visual simultaneous localization and mapping system
using a stereo camera. In front-end, the image data is used to execute feature detection and …

This paper presents experimental results of realtime sonar-based SLAM (simultaneous
localization and mapping) using probability-based landmark-recognition. The sonar-based …

Relative ranging and positioning is the basis to ensure the navigation safety of ships, and it
has a broad application prospect in various maritime activities, especially in the aspects of …

This article presents a computer-aided object detection and localization method from lidar 3-
D point cloud data. This topic of interest is in the framework of autonomous mooring, where …

Simultaneous localization and mapping (SLAM) is an active localization method for
Autonomous Underwater Vehicle (AUV), and it can mainly be used in unknown and complex …

Dynamically positioned vessels, used by offshore industry, use not only satellite navigation
but also different positioning systems, often referred to as 'reference'systems. Most of them …

The global positioning system (GPS) has become an indispensable navigation sensor for
field operations with unmanned surface vehicles (USVs) in marine environments. However …
