$\mathbb{Z}^{d}$-odometers and cohomology

Groups, Geometry, and Dynamics, 2019
Cohomology for actions of free abelian groups on the Cantor set has (when endowed with an order structure) provided a complete invariant for orbit equivalence. In this paper, we study a particular class of actions of such groups called odometers (or profinite actions) and investigate their cohomology.

Localization and mapping algorithm based on Lidar-IMU-Camera fusion

Journal of Intelligent and Connected Vehicles
Positioning and mapping technology is a difficult and hot topic in autonomous driving environment sensing systems. In a complex traffic environment, the signal of the Global Navigation Satellite System (GNSS) will be blocked, leading to inaccurate ...

Improved grid mapping technology based on Rao-Blackwellized particle filters and the gradient descent algorithm

Systems Science & Control Engineering, 2019
Recently, the Rao-Blackwellized particle filter (RBPF) has been used to solve the problem of simultaneous localization and mapping (SLAM). Using the odometer information of robot to calculate the proposed distribution requires a number of sampled ...

A New Map/Odometer Tunnel Positioning Method Using Random Forest-Derived Heading Estimation

IEEE Open Journal of Intelligent Transportation Systems
In global navigation satellite system (GNSS)-denied scenarios, odometer/inertial navigation system (INS) integration for train positioning tends to diverge due to accumulated attitude errors caused by uncorrected sensor drift.

The miscalibration of the honeybee odometer

We examine a series of articles on honeybee odometry and navigation published between 1996 and 2010, and find inconsistencies in results, duplicated figures, indications of data manipulation, and incorrect calculations. This suggests that redoing the experiments in question is warranted.
