Abstract

Summary

The field of unmanned aerial vehicle (UAV) technology is rapidly advancing and has become increasingly popular in various fields, including surveying and mapping. The ability of UAVs to capture high-resolution images of the Earth’s surface with ease and precision has made them an invaluable tool for collecting data in remote and hard-to-reach areas. However, the accuracy of the data obtained through UAVs is a critical factor that must be carefully evaluated to ensure the reliability and effectiveness of the data collected. The paper focuses on exploring different methodologies for determining the accuracy of UAV data processing and approaches for preliminary assessment based on Ground Sampling Distance (GSD). The DJI Phantom 4 Professional UAV was used for data collection, and the Agisoft PhotoScan Professional software was employed for processing. To evaluate the accuracy, the study calculated deviations of control points, and the method was applied to a flat terrain area and a ravine area. Additionally, the method of determining deformation of linear contours and areas was tested for the construction site of a technical maintenance station during the installation of column foundations. The experiments revealed that the maximum error value ranged from 1 to 3 GSD, indicating the feasibility of performing a preliminary accuracy assessment of low-cost UAV data based on the camera’s resolution parameter. The study’s findings have significant implications for the field of UAV technology, as they can help pave the way for the development of more efficient and reliable data collection techniques. Moreover, the research can provide valuable insight into improving the accuracy of UAV data processing, which can have a considerable impact on fields such as surveying, mapping, and remote sensing. By expanding our understanding of the accuracy of UAV data, we can unlock new opportunities for scientific research and exploration, leading to advances in various fields.
