  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

  2. 2. The World in 3D : Geospatial Segmentation and Reconstruction

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : David Robín Karlsson; [2022]
    Keywords : deep learning; ai; machine learning; geospatial; gis; heightmap; semantic segmentation; satellite imagery; aerial imagery;

    Abstract : Deep learning has proven a powerful tool for image analysis during the past two decades. With the rise of high resolution overhead imagery, an opportunity for automatic geospatial 3D-recreation has presented itself. This master thesis researches the possibil- ity of 3D-recreation through deep learning based image analysis of overhead imagery. READ MORE

  3. 3. CNN-Based Methods for Tree Species Detection in UAV Images

    University essay from Linköpings universitet/Datorseende

    Author : Olle Sievers; [2022]
    Keywords : Machine Learning; CNN; UAV; Tree Species; Deep Learning; Tree Species Detection; Detection;

    Abstract : Unmanned aerial vehicles (UAVs) with high-resolution cameras are common in today’s society. Industries, such as the forestry industry, use drones to get a fast overview of tree populations. READ MORE

  4. 4. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maximilian Rafael Huber; [2021]
    Keywords : physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Abstract : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. READ MORE

  5. 5. Using remote sensing and land abandonment as a proxy for long-term human out-migration. A Case Study: Al-Hassakeh Governorate, Syria

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Berit Mohr; [2021]
    Keywords : geography; GIS; remote sensing; Syria; vegetation indices; land abandonment; Earth and Environmental Sciences;

    Abstract : The topic of human migration and displacement has become more important in recent years and will continue to do so in the following decades. Voices become louder claiming that climate change is a driving factor for increased displacement and migration. READ MORE
