Abstract
The paper describes a technique for restoring images distorted by blurring from an unmanned aerial vehicle (UAV). Image reconstruction occurs using the point spread function (PSF), which is calculated based on a priori information about the basic flight and photographing parameters, as well as the physical properties of the optical system used. Well-known methods of image processing are used, such as restoration using the Wiener method, Lucy-Richardson method, Tikhonov method, and blind deconvolution method.
