   Sammanfattning : The goal of this thesis has been global geolocalization using only visual input and a 3D database for reference. In recent years Convolutional Neural Networks (CNNs) have seen huge success in the task of classifying images. The flattened tensors at the final layers of a CNN can be viewed as vectors describing different input image features. LÄS MER

3. 2. Development and Evaluation of a Robocentric SLAM Algorithm

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

   Författare :Max Holmberg; [2018]
   Nyckelord :;

   Sammanfattning : In this master thesis the front end of a Simultaneous Localization And Mapping(SLAM) system is developed in the programming language C++ and themeta-operating system ROS (Robot Operating System). The algorithms are based onprevious work done at the Swedish defense research agency (FOI) and are a part of aGPS free positioning system developed for military use. LÄS MER

4. 3. A Hybrid Approach to GPS-Free Geolocation over LoRa

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Jonas Danebjer; Valthor Halldórsson; [2018]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The last few years have seen a rapid expansion within the area of the Internet ofThings (IoT). For many IoT applications, such as asset tracking and distributedsensor networks, the problem of localization (i.e. determining the physical loca-tion of nodes in the network) is fundamental. LÄS MER
