  1. 1. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Richard Hedlund; [2019]
    Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.

  2. 2. RGB and Multispectral UAV image classification of agricultural fields using a machine learning algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sigurbjörn Jónsson; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; UAV; classification; Random Forest; Geomatics; segmentation; Earth and Environmental Sciences;

    Abstract : A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. READ MORE

  3. 3. Aerial Thermography Inspections in Large-Scale PV Plants

    University essay from Högskolan Dalarna/Energiteknik

    Author : Salvador Selva Marti; [2018]
    Keywords : Infrared thermography inspection; large-scale PV plants; drone; unmanned aerial vehicles; Quintas Energy; operation and maintenance; monitoring operations;

    Abstract : In order to successfully compete against the use of fossil fuels to generate electricity, one of the challenges in the photovoltaic (PV) business currently in focus is on the asset management of large PV plants, in which developing control techniques to prognosticate and evaluate the future energy performance will be essential. Infrared thermography inspections can give meaningful support to assess the quality and performance of PV modules. READ MORE

  4. 4. Deep learning navigation for UGVs on forests paths

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

    Author : Linus Lind; [2018]
    Keywords : ;

    Abstract : Artificial intelligence and machine learning have seen great progress in recent years. In this work, we will look at the application of machine learning in visual navigational systems for unmanned vehicles in natural environments. READ MORE

  5. 5. Evaluation of digital terrain models created in post processing software for UAS-data : Focused on point clouds created through block adjustment and dense image matching

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS; Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Sabina Assefha; Matilda Sandell; [2018]
    Keywords : UAS; DTM; Pix4D; UAS Master; Block adjustment; Photogrammetry; UAS; DTM; Pix4D; UAS Master; Blockutjämning; Fotogrammetri;

    Abstract : Lately Unmanned Aerial Systems (UAS) are used more frequently in surveying. With broader use comes higher demands on the uncertainty in such measurements. The post processing software is an important factor that affects the uncertainty in the finished product. READ MORE
