Research on the Integrated Navigation Technology of SINS with Couple Odometers for Land Vehicles

open access: yesSensors, 2020
Autonomous and accurate acquisition of the position and azimuth of the vehicle is critical to the combat effectiveness of land-fighting vehicles. The integrated navigation system, consisting of a strap-down inertial navigation system (SINS) and odometer (

$Z^{d}$-odometers and cohomology

open access: yes, 2017
Cohomology for actions of free abelian groups on the Cantor set has (when endowed with an order structure) provided a complete invariance 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. We show that for a free, minimal $\Z^{d}$-odometer,

Straightness Measurement Based on FOG-IMU and Shearer Motion Constraints for Longwall Coal Mining

open access: yesAdvanced Devices & Instrumentation
Straightness measurements of fully mechanized coal faces are a core requirement for intelligent, comprehensive coal mining. In coal mining, using an inertial measurement unit (IMU) assisted by an odometer for straightness measurement is vital for ...

Improved LiDAR Localization Method for Mobile Robots Based on Multi-Sensing

open access: yesRemote Sensing, 2022
In this paper, we propose a localization method applicable to 3D LiDAR by improving the LiDAR localization algorithm, such as AMCL (Adaptive Monte Carlo Localization).

Speed Consistency in the Smart Tachograph

open access: yesSensors, 2018
In the transportation sector, safety risks can be significantly reduced by monitoring the behaviour of drivers and by discouraging possible misconducts that entail fatigue and can increase the possibility of accidents.

Rotated odometers and actions on rooted trees

open access: yesFundamenta Mathematicae, 2023
A rotated odometer is an infinite interval exchange transformation (IET) obtained as a composition of the von Neumann-Kakutani map and a finite IET of intervals of equal length. In this paper, we consider rotated odometers for which the finite IET is of intervals of length $2^{-N}$, for some $N \geq 1$.

Underground multi-sensor integrated navigation system

open access: yesGong-kuang zidonghua, 2019
In view of problems of high cost of high-precision inertial navigation of underground vehicle and large drift of low-cost MEMS inertial sensor, an underground multi-sensor integrated navigation system was proposed, which uses bluetooth ranging ...

Human odometer is gait-symmetry specific [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2009
In 1709, Berkeley hypothesized of the human that distance is measurable by ‘the motion of his body, which is perceivable by touch’. To be sufficiently general and reliable, Berkeley's hypothesis must imply that distance measured by legged locomotion approximates actual distance, with the measure invariant to gait, speed and number of steps.
