| Summary: | In this article, we will consider and compare methods for eliminating distortions
in the original images obtained from an unmanned aerial vehicle. The main goal
of these methods is to increase the contrast and accuracy of determining the
coordinates of objects of interest relative to the background. To conduct the study,
aerial work is performed, during which initial images of the underlying surface with
different exposure times are obtained, as well as data from the unmanned aerial
vehicle navigation module. Further, cameral processing of the received materials
is carried out. The exact centers for photographing each image are calculated
and orthophotomaps of the area are built. Then we have evaluated the contrast
and accuracy of determining the coordinates of objects of interest relative to the
background on the orthophotomaps of the area built from the original and restored
images using various methods. |
