Abstract: An unmanned aerial vehicle is a reusable robot that autonomously takes off into the air and flies without a crew, using software or under the direct control of an operator located at a ground control station, via a two-way radio communication channel. It is capable of carrying payloads, imaging equipment, monitoring devices, and is used for reconnaissance of both aerial and aquatic environments [1]. Currently, the applications of drones are expanding rapidly, becoming a distinct sector in manufacturing [2]. Globally, there’s an increasing trend in using unmanned aerial vehicles to address engineering tasks. Innovations in manufacturing allow for increased speed and improved quality in executing these tasks. The methodology for determining the spatial parameters of excavations using unmanned aerial vehicles (UAVs) is an important tool for surveyors, geologists, builders, and other professionals working in the fields of surveying, cartography, and construction. This methodology streamlines and expedites the process of obtaining excavation data, which is significant for building design, land assessment, and addressing environmental tasks. Primarily, the use of UAVs allows for obtaining high-quality aerial photographs and data using various sensors such as LiDAR, multispectral cameras, among others. These data ensure high precision and provide detailed information about the terrain morphology, including topography, excavation depth, their shape, and dimensions. The methodology comprises several stages: mission planning, data collection, processing, and analysis of the acquired data. Data collection involves executing the flight, capturing images, and gathering additional parameters. Data processing is conducted using specialized software to create accurate digital models of excavations and their parameters. The result of using this methodology is obtaining precise geodetic data that can be utilized for various purposes such as construction project planning, land resource management, studying the geological structure of the terrain, among others. Considering the speed of data collection and its high accuracy, the methodology for determining the spatial parameters of excavations using UAVs is a powerful tool for modern geodetic and construction planning. It contributes to efficient resource utilization and ensures high data quality. The use of unmanned aerial vehicles (UAVs) in aerial surveying is rapidly increasing due to the significantly lower cost compared to manned aircraft. Aerial photography is an effective tool for performing engineering-surveying works, geophysical research, and various types of monitoring. Typically, the primary duty assigned to UAV systems is reconnaissance of hard-to-reach areas[4]., where obtaining information using ground methods is challenging or even hazardous to human health and life. Besides military applications, employing UAV systems enables a rapid and cost-effective method for surveying remote areas, periodic monitoring of designated zones, digital imaging for geodetic purposes, and in cases of emergency situations. The information acquired by onboard monitoring systems should be transmitted in real-time to the control center for processing and making informed decisions[5]. Object of study - technology of using unmanned aerial vehicles to determine the spatial parameters of excavations. Subject of research - features of UAV (Unmanned Aerial Vehicle) imaging using the Fimi X8 SE 2020 drone [3]. The aim of the work is to develop and implement an efficient method for determining the parameters and volumes of excavations using data obtained during aerial imaging from unmanned aerial vehicles (UAVs). Goal of research - The aim of the work is to analyze and implement an effective method for determining the parameters and volumes of excavations using data obtained during aerial surveys from unmanned aerial vehicles (UAVs). The goal is to improve the accuracy and speed of excavation volume measurements compared to traditional methods, such as ground-based measurements. Research methods: experimental, observational, comparative, analytical. This master’s thesis describes the determination of spatial parameters of excavations using the Fimi X8 SE 2020 unmanned aerial vehicle [3]. The calculation of excavation volumes using a point cloud obtained by photogrammetric and classical methods (using electronic theodolite data) yielded the following results: the volume calculated by ground-based method - 3659.5 m?, by photogrammetric method - 3676.6 m?.
