Consensus and formation control on SE (3) for switching topologies

J Thunberg, J Goncalves, X Hu - Automatica, 2016 - Elsevier
This paper addresses the consensus problem and the formation problem on SE (3) in multi-
agent systems with directed and switching interconnection topologies. Several control laws …

From angular manifolds to the integer lattice: Guaranteed orientation estimation with application to pose graph optimization

L Carlone, A Censi - IEEE Transactions on Robotics, 2014 - ieeexplore.ieee.org
Pose graph optimization from relative measurements is challenging because of the angular
component of the poses: the variables live on a manifold product with nontrivial topology …

Synchronization problems in computer vision with closed-form solutions

F Arrigoni, A Fusiello - International Journal of Computer Vision, 2020 - Springer
