Residual Kalman Dynamics for Event-Based UAV Forecasting
Per Nyblom, Hannes Ovrén, David Gustafsson
We study short- and mid-horizon UAV bounding-box forecasting on the FRED event-camera dataset. We use a constant-velocity Kalman filter over a full center-size box state as a stron…
Drone Detection Using a Low-Power Neuromorphic Virtual Tripwire
Anton Eldeborg Lundin, Rasmus Winzell, Hanna Hamrell +2
Small drones are an increasing threat to both military personnel and civilian infrastructure, making early and automated detection crucial. In this work we develop a system that us…
Trajectory Representation and Landmark Projection for Continuous-Time Structure from Motion
Hannes Ovrén, Per-Erik Forssén
This paper revisits the problem of continuous-time structure from motion, and introduces a number of extensions that improve convergence and efficiency. The formulation with a $\ma…
Spline Error Weighting for Robust Visual-Inertial Fusion
Hannes Ovrén, Per-Erik Forssén
In this paper we derive and test a probability-based weighting that can balance residuals of different types in spline fitting. In contrast to previous formulations, the proposed s…
Efficient Multi-Frequency Phase Unwrapping using Kernel Density Estimation
Felix Järemo Lawin, Per-Erik Forssén, Hannes Ovrén
In this paper we introduce an efficient method to unwrap multi-frequency phase estimates for time-of-flight ranging. The algorithm generates multiple depth hypotheses and uses a sp…
