A Discrete-Time Attitude Observer on SO(3) for Vision and GPS Fusion
Alireza Khosravian, Tat-Jun Chin, Ian Reid +1
This paper proposes a discrete-time geometric attitude observer for fusing monocular vision with GPS velocity measurements. The observer takes the relative transformations obtained…
A Branch-and-Bound Algorithm for Checkerboard Extraction in Camera-Laser Calibration
Alireza Khosravian, Tat-Jun Chin, Ian Reid
We address the problem of camera-to-laser-scanner calibration using a checkerboard and multiple image-laser scan pairs. Distinguishing which laser points measure the checkerboard a…
Observers for invariant systems on Lie groups with biased input measurements and homogeneous outputs
Alireza Khosravian, Jochen Trumpf, Robert Mahony +1
This paper provides a new observer design methodology for invariant systems whose state evolves on a Lie group with outputs in a collection of related homogeneous spaces and where…
