Event-Based Visual Odometry on Non-Holonomic Ground Vehicles

Wanting Xu, Si'ao Zhang, Li Cui +2

Despite the promise of superior performance under challenging conditions, event-based motion estimation remains a hard problem owing to the difficulty of extracting and tracking st…

Tight Fusion of Events and Inertial Measurements for Direct Velocity Estimation

Wanting Xu, Xin Peng, Laurent Kneip

Traditional visual-inertial state estimation targets absolute camera poses and spatial landmark locations while first-order kinematics are typically resolved as an implicitly estim…

Spatio-Temporal Calibration for Omni-Directional Vehicle-Mounted Event Cameras

Xiao Li, Yi Zhou, Ruibin Guo +3

We present a solution to the problem of spatio-temporal calibration for event cameras mounted on an onmi-directional vehicle. Different from traditional methods that typically dete…

Globally-Optimal Contrast Maximisation for Event Cameras

Xin Peng, Ling Gao, Yifu Wang +1

Event cameras are bio-inspired sensors that perform well in challenging illumination conditions and have high temporal resolution. However, their concept is fundamentally different…

Globally-Optimal Event Camera Motion Estimation

Xin Peng, Yifu Wang, Ling Gao +1

Event cameras are bio-inspired sensors that perform well in HDR conditions and have high temporal resolution. However, different from traditional frame-based cameras, event cameras…

Efficient Globally-Optimal Correspondence-Less Visual Odometry for Planar Ground Vehicles

Ling Gao, Junyan Su, Jiadi Cui +3

The motion of planar ground vehicles is often non-holonomic, and as a result may be modelled by the 2 DoF Ackermann steering model. We analyse the feasibility of estimating such mo…

Continuous Event-Line Constraint for Closed-Form Velocity Initialization

Peng Xin, Xu Wanting, Yang Jiaqi +1

Event cameras trigger events asynchronously and independently upon a sufficient change of the logarithmic brightness level. The neuromorphic sensor has several advantages over stan…

Visual Odometry with an Event Camera Using Continuous Ray Warping and Volumetric Contrast Maximization

Yifu Wang, Jiaqi Yang, Xin Peng +5

We present a new solution to tracking and mapping with an event camera. The motion of the camera contains both rotation and translation, and the displacements happen in an arbitrar…
