On the Perspectives of Image-to-Lidar Constraints in Dynamic Network Optimisation

Jan Skaloud, Davide Antonio Cucci, Laurent Valentin Jospin, Kyriaki Mouzakidou

The evolution of airborne mapping witnesses the introduction of hybrid lidar-camera systems to enhance data collection, i.e. to obtain simultaneously high-density point-cloud and texture. Yet, the common adjustment of both optical data streams is a nontriv ...

Generalization of point-to-point matching for rigorous optimization in kinematic laser scanning

Jan Skaloud, Stéphane Guerrier, Aurélien Arnaud Brun

In the scope of rigorous sensor fusion in kinematic laser scanning, we present a qualitative improvement of an automated retrieval method of lidar-to-lidar 3D correspondences in terms of accuracy and speed, where correspondences are locally refined shifts ...

Indoor-Positioning in DVB-T/T2 Single-Frequency Networks Using Inverse Passive Radar Approach

Jan Skaloud

Wide signal bandwidth and precisely time-synchronized single-frequency network predetermines DVB-T and its successor DVB-T2 for Signals of Opportunity (SoP) radio positioning. Previously published methods were based on demanding OFDM symbol synchronization ...

Linear Estimation of Deterministic Accelerometer Errors

Jan Skaloud

The deterministic errors of an accelerometer comprise the prevailing i) bias, ii) scale factor, and iii) non-orthogonality. Together, these errors result in a nonlinear measurement model, which is conventionally solved via an iterative nonlinear least-squa ...

Model-Based Fusion of GNSS and Multiple-IMUs

Jan Skaloud

Autonomous navigation of drones in environments with intermittently poor GNSS reception remains a complex problem with small and lightweight sensors. Conventional kinematic frameworks, fusing inertial sensors with satellite positioning, often falter under ...

Synthetic Wind Estimation for Small Fixed-Wing Drones

Jan Skaloud, Gabriel François Laupré, Pasquale Longobardi

Wind estimation is crucial for studying the atmospheric boundary layer. Traditional methods such as weather balloons offer limited in situ capabilities; besides an Air Data System (ADS) combined with inertial measurements and satellite positioning is requi ...
