Abstract
Abstract. This work presents a robust calibration framework for marine LiDAR systems by leveraging spherical targets to jointly estimate boresight angles and lever arm offsets. The use of spheres provides a geometrically consistent and orientation-independent reference, enabling accurate calibration even in complex marine environments. To evaluate the proposed approach, a synthetic data generation algorithm was developed to simulate LiDAR scans over spherical targets, allowing controlled experiments across a wide range of sensor configurations. Furthermore, the calibration method was validated using real LiDAR data collected from a hydrographic survey vessel. Due to the calibration, the distance between the surveyed spherical centers and their estimated center positions from LiDAR point clouds is minimised to an RMS error of 0.036 m, which is within the range of the accuracy of the POS MV navigation system. We finally introduce a low cost in-house mobile LiDAR system integrating similar sensors in the ROS environment in order to address the challenges of obtaining LiDAR data in varying environmental conditions.
Abstract. Airborne laser bathymetry (ALB) is an efficient and accurate tool for mapping submerged environments, particularly shallow water bodies that are difficult to access with surface vessels. Modern ALB systems can achieve accuracies comparable to SONAR. However, multiple factors, including geo-referencing, water...

LiDAR-based SLAM (Simultaneous Localization and Mapping) and LIO (LiDAR-inertial odometry) algorithms are often used for precise navigation of unmanned aerial vehicles, especially during interactions with the aerial robot's environment. However, the performance of these algorithms is greatly dependent on the scenario,...

Terrestrial laser scanning (TLS), also referred to as terrestrial LiDAR, has become an essential close-range remote sensing technique for high-precision engineering surveying, deformation monitoring, industrial inspection, and cultural heritage documentation. The geometric reliability of TLS point clouds strongly depen...

There is a renewed international effort to establish a sustained human presence on the lunar surface, e.g., the confirmed existence of water ice at the lunar poles has rendered the exploration of these regions particularly compelling. Current proposed missions predominantly employ robotic rovers, the majority of which...

Recently, unmanned aerial vehicle (UAV)-borne radar (radio detection and ranging) calibration system has been found to be promising in replacing the conventional balloon-based calibration system which incurs challenges of deciding the reference location. However, in the UAV-borne calibration system major challenges ari...
