Stereo Hybrid Event-Frame (SHEF) Cameras for 3D Perception
Ziwei Wang, Liyuan Pan, Yonhon Ng +2
Stereo camera systems play an important role in robotics applications to perceive the 3D world. However, conventional cameras have drawbacks such as low dynamic range, motion blur…
Uncertainty Estimation of Dense Optical-Flow for Robust Visual Navigation
Yonhon Ng, Hongdong Li, Jonghyuk Kim
This paper presents a novel dense optical-flow algorithm to solve the monocular simultaneous localization and mapping (SLAM) problem for ground or aerial robots. Dense optical flow…
Equivariant Systems Theory and Observer Design for Second Order Kinematic Systems on Matrix Lie Groups
Yonhon Ng, Pieter van Goor, Tarek Hamel +1
This paper presents the equivariant systems theory and observer design for second order kinematic systems on matrix Lie groups. The state of a second order kinematic system on a ma…
Attitude Observation for Second Order Attitude Kinematics
Yonhon Ng, Pieter van Goor, Robert Mahony +1
This paper addresses the problem of estimating the attitude and angular velocity of a rigid object by exploiting its second order kinematic model. The approach is particularly usef…
