Abstract

Paper covers the results of calibration of digital camera for an unmanned aerial vehicle (UAV) based on aerial materials of the test site. Field calibration involved comparison of the fixed positions of 36 reference points marked in the aerial image against the data of tacheometric shooting. The shooting materials received were processed in Delta Digitals and Surfer software complexes. Statistica 10 software allowed to build variation series in the form of histograms based on the data of the comparison of actual position marks of the reference points. Digital models of the test object with marks made on them, vector diagrams of geometric distortions of mark positions defined according to the tacheometric shooting and mark positions defined in the aerial image taken with the help of the UAV, 3-D models of the distortion of the mark positions of the test object were built in the Surfer software package. The research has shown that the accuracy of a photographic plan of the test site created as a result of the processing of aerial materials using UAV allows to perform a large-scale mapping in order to record road traffic accidents. Consequently, this gives grounds to make a conclusion on the possibility to use shooting materials taken with the help of the unmanned aerial vehicle in solving geodetic problems and shooting small areas for the large-scale mapping.
