The task of estimating the UAV flight velocity using video sequences obtained from on-board video camera is considered. A method for estimating the displacement of X and Y coordinates for adjacent video frames based on finding of similar blocks of the two frames and taking into account their informativity is proposed. It is proposed to provide an acceptable speed of the method to use fast edge clustering. A test video sequence for verification of methods of motion estimation is formed. In a comparative analysis with the most well-known methods, it is shown that the proposed method provides both the best accuracy of the estimates and the smallest number of abnormal estimates.

Key words: image analysis, image similarity measures, clustering, optical navigation.
