Concept of using unmanned aerial vehicles to locate pollution in industrial area
(Wydawnictwa AGH, 2023) Nowicki, Dawid; Suder-Dębska, Katarzyna; Czajka, Ireneusz
More and more attention is being paid to the impact of industry on the environment and people’s surroundings. One type of pollution is the noise that is generated by technological apparatus. It is necessary to develop new tools that will be able to survey noise in large industrial areas. This paper presents a concept of using unmanned aerial vehicles to generate acoustic maps of a surveyed area. One of the tools that is required for this purpose is aerial photogrammetry, which is used to generate a numerical terrain model from a series of photographs. The methodology and results of the simulation study of the effect of the data-acquisition-process parameters (flight altitude and transverse and longitudinal overlay levels of images) on the quality of the generated numerical terrain model and the generating time are presented in this paper.

Manual versus Digital Classification of UAV Images in Oak Phenological Studies
(Wydawnictwa AGH, 2025) Będkowski, Krzysztof
This research concerns the phenological phenomenon of the autumn discolorations of sessile oak leaves as the trees prepare for winter dormancy. Sessile oak trees were categorized into five classes according to the general colors of their crowns: from green to brown. Low-altitude UAV-acquired images from the visible B, G, and R bands were used, compared, and evaluated against the results of several classification methods: those that were carried out in the field, visually based on orthomosaic observations, and four variants of digital classification. The analysis showed that those methods that were based on observer assessments were highly subjective. At the same time, there was also the problem of the reference data to which the results of the individual methods could be referred. It was expected that the analyzed phenomenon of tree-crown discoloration would be better visible in aerial photographs than in field observations"," However, visual color classifications using orthomosaics can be too subjective (as has been shown). It is recommended to use supervised digital classification with a careful selection of reference (training) objects. To switch from pixel-classification results to individual tree classifications, a novel approach was adopted in which the class value that was most abundant within the images of each canopy (determined by the supervised classification method selected) could be used. Among the supervised digital-classification methods that were applied, the results that were closest to the classification performed in the field were obtained by using the ML and Fisher algorithms (followed by kNN).

Optimising UAV data acquisition and processing for photogrammetry - a review
(Wydawnictwa AGH, 2023) Pargieła, Karolina
Unmanned aerial vehicles (UAVs) are used to acquire measurement data for an increasing number of applications. Photogrammetric studies based on UAV data, thanks to the significant development of computer vision techniques, photogrammetry, and equipment miniaturization, allow sufficient accuracy for many engineering and non-engineering applications to be achieved. In addition to accuracy, development time and cost of data acquisition and processing are also important issues. The aim of this paper is to present potential limitations in the use of UAVs to acquire measurement data and to present measurement and processing techniques affecting the optimisation of work both in terms of accuracy and economy. Issues related to the type of drones used (multi-rotor, fixed-wing), type of shutter in the camera (rolling shutter, global shutter), camera calibration method (pre-calibration, self-calibration), georeferencing method (direct, indirect), technique of measuring the external images orientation parameters (RTK, PPK, PPP), flight design methods and the type of software used were analysed.

Receiving data from UAV for geodetic road inventary
(Wydawnictwa AGH, 2018) Piech, Izabela; Kwinta, Andrzej|Krzyszycha, Marcin
This study presents the outline of measurement techniques using an unmanned aerial vehicle (UAV) and the elaboration of data that results from its processing. Nowadays, measurement with the use of drones is developing very quickly. There are many factors, but the biggest impact has to be the technological progress, which brings new systems, techniques, and measuring instruments every year with much-better parameters and improved accuracy. In the era of the Internet and computerization, elaboration of the measurement results from these devices becomes more transparent and easy to use, therefore, traditional paper maps are being replaced by digital maps, which are much more convenient to use when correcting errors or when applying new data. The area where the subject of the work has been studied is located in the voivodeship of Kielce. The area that was surveyed is the National Road No. 7 on the mileage section from 561.6 to 563.3. This study was made possible thanks to Flytech Technology Co., Ltd., of Krakow for providing the necessary materials. This study aims to show one of the many aspects in which an unmanned aerial vehicle can be used. Data from the UAV method are new sources of information about the study area, therefore, an attempt to acquire data and survey the road infrastructure has contributed to completing the messages contained in this report. The idea was to present knowledge on the technical conditions and location of public roads in Poland as well as the UAV technique, its parameters, and specifications of the used measuring equipment.

The UAV Technology as a Future-Oriented Direction in the Development of Low-Ceiling Aerial Photogrammetry
(2013) Mikrut, Sławomir; Głowienka-Mikrut, Ewa; Michałowska, Krystyna
The paper reviews current issues related to UAV flights. The relevant research has been conducted all over the world for a dozen or so years in various scientific research centres. The paper presents results of research obtained by various agencies, and shows the concept of research on aerial vehicles completed with the cooperation of the AGH University of Science and Technology in Krakow, Poland. Research issues focus mainly on geometry and radiometry of recorded images. That technology seems to be highly future-oriented due to its low costs as compared to traditional aerial photogrammetry.

Verification of the geometrical representation of buildings in cadastre using UAV photogrammetry
(Wydawnictwa AGH, 2021) Karabin, Marcin; Bakuła, Krzysztof; Łuczyński, Robert
The aim of this study was to determine the potential benefits of using UAV-based data to verify the accuracy of the geometry of the outlines of buildings registered in a cadastral database, and to investigate the potential use of data from UAV platforms in measuring the buildings. The authors examined whether the acquisition of data from UAVs can replace field measurements or only support them. The advantages and disadvantages of such data acquisition methods, compared with more well-established measurement methods, were identified.
