Kvalita přímého georeferencování snímků pořízených bezpilotním letadlem

Abstract

The bachelor thesis deals with the issue of georeferencing outputs obtained by processing RGB images taken by an unmanned aerial vehicle. Specifically, it deals with the evaluation of the quality of georeferencing of the digital elevation model and orthomosaic when using direct and indirect georeferencing methods. Data collection and evaluation took place on one flat location with a minimal elevation and also on another very rugged location, where the difference in elevation reached tens of meters. A set of control points was used to check the accuracy of georeferencing. The influence of the number of insertion points for the indirect georeferencing method was also evaluated. The resulting comparison of the two methods turned out to be similar with a slight superiority of the accuracy of indirect georeferencing.
