    Letecké multispektrálne snímkovanie v poľnohospodárskom odvetví
    (University of Žilina, 2024) Šmidt, Marco; Veľký, Patrik
    This thesis focuses on the possibilities of applying airborne detection in many bands. Possibilities of multispectral detection in direction of use such as animal monitoring or scarecrow placement. In another direction of using thermal imaging for finding temperature anomalies or obtaining information from UAV sensors to improve economics in agriculture, light reflectance, electromagnetic spectrum, comparing satellites and UAVs in agriculture, and vegetation indices. The analysis of the studies was based on simulations and calculations followed by laboratory tests and external measurements. Using certain sensors operating in the corresponding regions of the frequency spectrum, the detection ranges of the drones were used to find the outputs derived from the calculated and simulated values, where a comparison of the studies followed.

    Analysis of new progressive diagnistic methods in the area of aircraft maintenance
    (University of Zilina, 2021) Supuka, Matej; Hrúz, Michal
    In the area of aircraft maintenance, we commonly meet with the problem of corrosion, detection of which is one of the primary obstacles. Implementation of modern sensing techniques has a potential to bring many benefits. The objective of this work is to analyze technologies, their potential applications, and viability of switching to autonomous detection using computer aided sensing. Primary source of information were research articles from science databases such as ResearchGate and ScienceDirect. Available documents were analyzed and subsequently, useful information was extracted. First part deals with theretical knowledge about corrosion, based on which potential technologies were chosen. Those were then described, and their viability was analyzed, based on how well they could achieve our goals. Selected technologies have shown potential, however necessary solutions could not be found to enable fully switching tou autonomous computer detection. Although data acquired show many potential benefits that could arise from partial implementation of these technologies combined fith old fashioned visual inspection.

    DETEKCIA A OCHRANA OBJEKTOV PROTI PREVÁDZKE BEZPILOTNÝCH LIETADIEL
    (Žilinská univerzita v Žiline, 2020) Bujna, Erik; Škultéty, Filip
    The main topic of this bachelor thesis is the detection and protection of objects against the operation of unmanned aerial vehicles (UAVs). The necessity of addressing this issue is due to the increasing prevalence of UAVs and increase in reports of airspace penetrations by unauthorised UAV operations. The aim of the bachelor thesis is to analyse the problem and provide an overview of the possibilities and methods of protection against unmanned aircraft. The first part of the bachelor thesis provides a brief overview of the issue, including terminology, an overview of current legislation, the possibility of using unmanned aircraft together with incidents that have also become the subject of the problem. The following chapters examine in more detail the possibilities of detection and protection against unmanned aircraft. The comparative method compares the positive and negative aspects of individual detection methods. In the third chapter are provided specific solutions which are based on the methods of security protection and defined principles to operators of areas with the necessary security protection. The conclusion of the bachelor thesis includes the analysis of the Bratislava airport surrounding, the definition of the protective zones of airport together with the protective zones of navigation devices. The result is a proposal for implementation of detection system, which should to ensure regular and safe operation and to reduce the risk of flying unmanned aircraft over the airport. The proposal of securing the airport against UAVs offers the possibility to protect the nearest surroundings of the airport from the intrusion of unmanned aircraft and in case of disruption of the covered area of early warning and the possibility of responding to the threat.
