UTILIZATION OF UNMANNED AERIAL VEHICLES IN PHOTOGRAMMETRY

Abstract

The aim of the article is to provide information about utilization of unmanned aircraft system for photogrammetric purposes. Basic principles of aerial photogrammetry, analysis of unmanned aircraft system and its application in photogrammetry are introduced. First part is devoted to utilization of unmanned aircraft system in comparison with commercial conventional aircraft. The photogrammetric system used for the realization of specific photogrammetric process from taking photos to data processing is also described. Consequently specific types of commercial aircraft and unmanned aircraft system used in aerial photogrammetry are listed. The inevitable part of theoretical preparation of data acquisition are cameras and sensors, programs for aircraft photo processing from unmanned aircraft vehicles and also other photogrammetric products used in aerial photogrammetry. Finally total expenses used for unmanned aircraft vehicle configuration, expenses for camera and other systems needed for successful action of aerial photogrammetry are analysed and compared with commercial aircrafts of same purpose.
