THE ANALYSIS OF THE DETERMINATION OF POINTS POSITIONS USING PHOTOGRAMMETRIC METHODS

ABSTRACT

This article was created as a result of research conducted within the master thesis. The purpose of the research was to analyze the accuracy of determining the actual position of the photographed points according to the calculated parameters. The accuracy of photos alignment was determined as parameters, which determine their external and internal orientation. In order to determine the location of the determined points, it was decided to follow the photogrammetric resection rule. In order to automate the measurement, the measurement session planning was omitted. The resulting deviations and linear displacements oscillate in millimeters. Analysis was performed for 3 levels of alignment accuracy. For each align level, line differences of photopoints coordinates obtained from photogrammetric model and total station measurements were analysed. There were also analysed horizontal and vertical directions of photopoints location. In this way were obtained parameters similar to “displacement” vector connecting points measured by total station and estimated from photogrammetric model.
