Indoor localisation continuous to be a topic of growing importance.
|
|
Despite the advances made, several profound problems are still present.
|
|
For example, estimating an accurate position from a multimodal distribution or recovering from the influence of faulty measurements.
|
|
Within this work, we solve such problems with help of Monte Carlo smoothing methods, namely forward-backward smoother and backward simulation.
|
|
In contrast to normal filtering procedures like particle filtering, smoothing methods are able to incorporate future measurements instead of just using current and past data.
|
|
This enables many possibilities for further improving the position estimation.
|
|
Both smoothing techniques are deployed as fixed-lag and fixed-interval smoother and a novel approach for incorporating them easily within a conventional localisation system is presented.
|
|
All this is evaluated on four floors within our faculty building.
|
|
The results show that smoothing methods offer a great tool for improving the overall localisation.
|
|
Especially fixed-lag smoothing provides a great runtime support by reducing timely errors and improving the overall estimation with affordable costs.
