Kirje Erinevate meetoditega loodud aerotriangulatsiooni täpsus maatriksaerofotode näitel(2013) Berg-Jürgens, Jaano; Liba, NataljaThe purpose of this bachelor thesis is to explore the opportunities of creating orthophotos in different photogrammetric softwares and to research the accuracy of aerial triangulation of aerial array photos in Photomod sofware. Previously has been researched several times geometrical accuracy creating orthophotos from aerial photos taken by both film and digital cameras. Used aerial array photos were given to Estonian University of Life Science by Estonian Land Board and those photos were taken in 7th of May in 2007 with camera UltraCam-D. Aerial triangulation was carried out with Photomod 5.1 software and two projects were created - the automatic and the manual. The difference between two projects is the method relative orientation was computed. The accuracy was analyzed with root-mean-squared-errors calculated by comparsion of check point coordinates measured on triangulated photo block and outdoor with GPS. Root-mean-squared-error of the automatic project was 0,415 m with accuracy 0,131 m. And the root-mean-squared-error of the manual project was 0,094 m with accuracy 0,030 m.
