Tvorba detailního digitálního modelu povrchu metodou pozemní fotogrammetrie

Abstract

This thesis is focused on creation of digital terrain model which is generated from taken RGB photos using of terrestrial photogrammetry. It was important to choose a suitable area with optimal characteristics for applied method evaluation. A part of this thesis is also assembly of own photography system for image acquisition. Practical side of this thesis has two main parts, which are acquisition of image and ground control points position. and then their processing with use of software Agisoft PhotoScan with the purpose to create digital terrain model of photographed area. Then this model is visually evaluated and statistically compared to official elevation data which is DMR 5G created by ČÚZK. The resulting mean difference of values between these models is 0.20 m. The highest positive difference was the value 0,75 m, on the other hand, the highest negative difference was 1.83 m.
