UAV fotogrammetriai felvételezés alkalmazhatósága hulladékdepóniák térbeli paramétereinek meghatározására egy szegedi hulladéklerakó példáján

Abstract

The study aims to compare the spatial parameters and volume estimates of a waste landfill in Szeged, using drone LIDAR (ALS) and photogrammetric (SfM) based point clouds. A further aim of the study is to demonstrate the applicability of drones for surveying and monitoring landfills. After processing the aerial photographs, volume estimates were performed in photogrammetric and CAD software, followed by point cloud processing software CloudCompare. Furthermore, the discrepancies between the point clouds were investigated. The results showed that the photogrammetric survey was sufficient to accurately determine the volume of the landfill and estimate future changes in the landfill.
