We present a mapping algorithm to compute large-scale magnetic field maps in indoor environments with approximate Gaussian process (GP) regression. Mapping the spatial variations in the ambient magnetic field can be used for 10-calization algorithms in indoor areas. To compute such a map, GP regression is a suitable tool because it provides...

In this paper, a simultaneous localization and mapping algorithm for tracking the motion of a pedestrian with a foot-mounted inertial measurement unit is proposed. The algorithm uses two maps, namely, a motion map and a magnetic field map. The motion map captures typical motion patterns of pedestrians in buildings that are constrained by e.g....

In this work, our focus is on indoor localization using the indoor magnetic field as a source of position information. This relies on the fact that ferromagnetic materials inside buildings cause the magnetic field to vary spatially. We jointly estimate the pose of a combined sensor module (containing a magnetometer) as well as the magnetic field...

Pedestrian indoor localization is a problem yet to have a solution that is as generally accepted as the Global Positioning System is for outdoor localization. An infrastructure-independent option is to leverage the data from Inertial Measurement Unit (IMU) sensors to determine position. An advantage of this approach is that these sensors are...

The company Kien 1 is developing Bluetooth Low Energy (BLE) speakers, consisting of a subwoofer and several satellite speakers. These subwoofer and satellite speakers will have a feature named Follow Me, which when enabled from a smartphone application, will play music only in the room where the user currently is. The BLE’s signals will...

Locating people inside buildings is still an unsolved problem. There is a lot<br/>of research going on in this field and many different solutions using different<br/>techniques have been proposed. However, there is no widely accepted indoor<br/>localization solution like how GPS is for outdoor localization due to less accuracy, higher hardware...

Indoor positioning has several variants as a result of multiple years of study on the topic. Using WiFi signals as the technology to compute the position of the target device is one of the most extended and researched techniques. WiFi Access Points are extensively deployed in all indoor environments where WiFi indoor localization has a potential...

Indoor localization provides for a much researched subject, as the complexity and size of many public buildings require extensive and properly designed methods to facilitate location specific processes. Indoor localization entails finding a qualitative description of the occupied area, that is human interpretable, rather than a quantitative...

The presented method provides for a possibility to perform graph-based indoor localization, by comparing the topological structure embedded in a mesh model to the topological structure of a semantically rich reference model, specifically a BIM. However different in nature and structure, both input sources can be converted to a graph of...

Travelling through airports can be quite a stressful experience for passengers. Airlines, such as KLM, want to make the journey of their passengers through airports as comfortable as possible. This thesis proposes an indoor localization system for airlines called AirLoc. The research question was: "Which airport specific indoor localization...

Indoor localization has gained considerable attention over the past decade because of the emergence of numerous location-aware services. Research works have been proposed on solving this problem by using wireless networks. Nevertheless, there is still much room for improvement in the quality of the proposed classification models. In the last...

Smartphones, or more general handhelds, which are commonly used for indoor localization purposes, are not a viable option in places where people do not carry them all the time, e.g., home and office. Alternatively using wearable devices brings along limitations in regards to power supply, processing capability and availability of sensors, which...

Indoor localization is a topic of significant interest for academic and in dustrial. For outdoors, we have Global Positioning System (GPS) working very well, but GPS does not work indoors and we spend more than 90% of the time indoors. Thus, there is a great need to find solution for this prob lem. Many technologies have been proposed for indoor...

At the most fundamental level, smart buildings deliver useful building services that make occupants productive. Smart asset management in hostipals starts with knowing the whereabouts of medical equipment. This paper investigates the subject of indoor localization of medical equipment in hospitals by defining functional spaces. In order to...

Indoor localization is a topic that has been investigated for more than a decade. Yet, no single system exists that is widely adopted as the de facto localization standard. From a research perspective the goal is to obtain a solution that is general, simple and accurate. As the number of devices in the Internet of Things grow, a new set of...

This Msc. Thesis builds upon a work-in progress called collocal which researched room-level indoor-localization. Localization is the action of estimating the position of a certain entity on a map. For example tracking the postion of furniture and other inventory in a building over a long period of time. To localize these entities other static...

In this thesis an existing method to localise phones in an indoor environment is extended. For this a new method to synchronise the clocks in presented. When looking at the different causes of localisation errors we conclude that the incorrect detection of the time of arrival (TOA) gives the largest errors. This is why we focus on the detection...

Many solutions have been proposed for indoor pedestrian navigation. Some rely on pre-installed sensor networks, which offer good accuracy but are limited to areas that have been prepared for that purpose, thus requiring an expensive and possibly time-consuming process. Such methods are therefore inappropriate for navigation in emergency...
