In-operation calibration of clock-bias and intrinsic parameters for pan-tilt-zoom cameras based on keypoint tracking

Larsen, Martin Vonheim; Haavardsholm, Trym Vegard; Mathiassen, Kim (2020-09-20)

We propose a method for jointly estimating intrinsic calibration and internal clock synchronisation for a pantilt- zoom (PTZ) camera using only data that can be acquired in the field during normal operation. Results show ...
Path Planning for UGVs Based on Traversability Hybrid A*

Thoresen, Marius; Nielsen, Niels Hygum; Mathiassen, Kim; Pettersen, Kristin Ytterstad (2021-02-01)

In this letter, a new method of path planning for unmanned ground vehicles (UGVs) on terrain is developed. For UGVs moving on terrain, path traversability and collision avoidance are important factors. If traversability ...
