Rolling-Shutter Modelling for Direct Visual-Inertial Odometry
David Schubert, Nikolaus Demmel, Lukas von Stumberg +2
We present a direct visual-inertial odometry (VIO) method which estimates the motion of the sensor setup and sparse 3D geometry of the environment based on measurements from a roll…
Efficient Derivative Computation for Cumulative B-Splines on Lie Groups
Christiane Sommer, Vladyslav Usenko, David Schubert +2
Continuous-time trajectory representation has recently gained popularity for tasks where the fusion of high-frame-rate sensors and multiple unsynchronized devices is required. Lie…
Visual-Inertial Mapping with Non-Linear Factor Recovery
Vladyslav Usenko, Nikolaus Demmel, David Schubert +2
Cameras and inertial measurement units are complementary sensors for ego-motion estimation and environment mapping. Their combination makes visual-inertial odometry (VIO) systems m…
Quantum cryptography with correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
The data transmission protocol, based on the use of a strongly correlated pair of laser beams, is proposed. The properties of the corresponding states are described in detail. The…
Secure quantum channels with correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
This work is the development and analysis of the recently proposed quantum cryptographic protocol, based on the use of the two-mode coherently correlated states. The protocol is su…
