Abstract
A model of the formation of a hyperspectral image by a space-scanning system due to the translational motion of the unmanned aerial vehicle on which it is installed is considered. The relationship between the angular deviation of the aircraft roll and the nature of geometric distortions of the hyperspectral image lines formed is determined. An algorithm of correction of introduced distortions according to the data of the inertial navigation system is presented. The results of modeling and processing of real images reveal acceptable correction quality and computational simplicity of the developed algorithm.
