Probabilistic Map Matching for Robust Inertial Navigation Aiding
Navigation, 2023 Robust aiding of inertial navigation systems in GNSS-denied environments is critical for the removal of accumulated navigation error caused by the drift and bias inherent in inertial sensors. One way to perform such an aiding uses matching of geophysical

High-Accuracy Off-Line Map-Matching of Trajectory Network Division Based on Weight Adaptation HMM
IEEE Access, 2020 In this paper, an accurate off-line map-matching (OM2) system is designed for complex trajectory networks. It is difficult to complex trajectories input into the hidden Markov model (HMM) directly.

Resolution-matched shadow maps [PDF]
ACM Transactions on Graphics, 2007 This article presents resolution-matched shadow maps (RMSM), a modified adaptive shadow map (ASM) algorithm, that is practical for interactive rendering of dynamic scenes. Adaptive shadow maps, which build a quadtree of shadow samples to match the projected resolution of each shadow texel in eye space, offer a robust solution to projective

Research on Multi-sensor Fusion Localization for Autonomous-rail Rapid Tram
Kongzhi Yu Xinxi Jishu, 2022 Traditional positioning methods, such as GNSS (global navigation satellite system) and location base service, have large positioning error when applied in complex traffic scenarios such as like tunnels buildings and viaducts.

Matching by Tone Mapping: Photometric Invariant Template Matching [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014 A fast pattern matching scheme termed matching by tone mapping (MTM) is introduced which allows matching under nonlinear tone mappings. We show that, when tone mapping is approximated by a piecewise constant/linear function, a fast computational scheme is possible requiring computational time similar to the fast implementation of normalized cross ...

On the optimal map in the 2-dimensional random matching problem [PDF]
, 2019 We show that, on a $2$-dimensional compact manifold, the optimal transport map in the semi-discrete random matching problem is well-approximated in the $L^2$-norm by identity plus the gradient of the solution to the Poisson problem $-\Delta f^{n,t} = \mu^

Geomagnetic/inertial navigation integrated matching navigation method
Heliyon, 2022 The accuracy of an a priori geomagnetic reference map is a significant constraint on the geomagnetic matching navigation method. Especially when the aircraft enters an unknown environment, it is impossible to accomplish the navigation task using ...

Map-Matching Using Shortest Paths [PDF]
ACM Transactions on Spatial Algorithms and Systems, 2018 We consider several variants of the map-matching problem, which seeks to find a path Q in graph G that has the smallest distance to a given trajectory P (which is likely not to be exactly on the graph). In a typical application setting,

Enhanced Map-Matching Algorithm with a Hidden Markov Model for Mobile Phone Positioning
ISPRS International Journal of Geo-Information, 2017 Numerous map-matching techniques have been developed to improve positioning, using Global Positioning System (GPS) data and other sensors. However, most existing map-matching algorithms process GPS data with high sampling rates, to achieve a higher ...
