Kombinace fotogrammetrie a laserového skenování z bezpilotních letadel pro tvorbu digitálního modelu terénu

Abstract

The bachelor thesis deals with the use of drones for the creation of a digital terrain model, specifically by combining photogrammetric processing and laser scanning. For this purpose, a set of RGB images was taken for the area of interest near the town Vítkov and laser scanning was performed. Based on the processing data, separate digital terrain models were derived for both methods, and their accuracy was determined by comparison with a set of own elevation points measured by the GNSS RTK method and by comparison with a digital terrain model derived from DMR 5G data. Subsequently, a combined digital terrain model was created by combining models from both techniques, which had to be modified by interventions at the junction of the two incoming models.
