Abstract
Quite often aerial survey made by unmanned aerial vehicle (UAV) is carried out using digital non-metric cameras that have rolling shutters. Variations in speed of a UAV and its angular elements of exterior orientation during aerial survey cause distortions in the images generated by the camera, which affects the accuracy of the processing results. The article shows the variations in the elements of exterior orientation during the operation of a rolling shutter and describes the way of its detection by flight recorder. The values of image distortion, caused by the variations in the angular elements of the exterior orientation of a snapshot, are calculated for the Sony Alpha A6000 digital non-metric camera.
