  1. 1. GPS-Free UAV Geo-Localization Using a Reference 3D Database

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Justus Karlsson; [2022]
    Keywords : Deep Learning; Machine Learning; ML; AI; UAV; GPS-Free; CNN; 3D CNN; GCNN; 3D Database; geolocalization; geo-localization; georegistration; Hidden Markov Model; HMM; satellite; satellite database; Batch-Hard; triplet loss; PyTorch Geometric;

    Abstract : 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. READ MORE

  3. 2. UAV geolocalization in Swedish fields and forests using Deep Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andreas Rohlén; [2021]
    Keywords : Unmanned Aerial Vehicle; Absolute Localization; Deep Learning; Convolutional Neural Network; Cross-View; Neural Network Interpretation; Obemannad Luftburet Fordon; Absolut Lokalisering; Djupinlärning; Convolutional Neural Network; Kors-Perspektiv; Neural nätverkstolkning;

    Abstract : The ability for unmanned autonomous aerial vehicles (UAV) to localize themselves in an environment is fundamental for them to be able to function, even if they do not have access to a global positioning system. Recently, with the success of deep learning in vision based tasks, there have been some proposed methods for absolute geolocalization using vison based deep learning with satellite and UAV images.

  4. 3. Airborne Angle-Only Geolocalization

    University essay from Linköpings universitet/Reglerteknik

    Author : Tove Kallin; [2021]
    Keywords : Angle-only; Bearing-only; Bearing; Geolocalization; Localization; Jammers; NLS; EKF; UKF; Cramér-Rao Lower Bound; Terrain; Elevation Data;

    Abstract : Airborne angle-only geolocalization is the localization of objects on ground level from airborne vehicles (AV) using bearing measurements, namely azimuth and elevation. This thesis aims to introduce elevation data of the terrain to the airborne angle-only geolocalization problem and to demonstrate that it could be applicable for localization of jammers. READ MORE
