Paper Abstract

This paper describes the method and algorithms for analysis of moving object image, which was obtained by Doppler laser radar. A Doppler image is 2D image, in which any pixel represents a value of Doppler shift (the radial velocity) for the area element of observed scene. It is difficult for human-operator to percept a Doppler image on radar display. However, Doppler image contains the greater amount ofinformation for computer analysis and automatic determination ofobject features. For features extraction of dynamic object, we propose to analyze the projections of Doppler image in coordinates an horizontal direction - Doppler shift and vertical direction - Doppler shift, named as Space-Doppler projections. SpaceDoppler projections are mutual associated images and they have unique form for each type of object. For example, SpaceDoppler projections of moving car look like letter H, have clearly recognizing areas of rotating wheels and car body. The detailed analysis of Space-Doppler projections allow to define the angular position of car wheels, the line of land osculation, line connecting centers of rotating wheels, size of wheels, space orientation of car and other features. This information allows to create the formalized description ofobserved object and to define its type.
