Target 3-D structure inversion based on electro-optical fusion.

Aiming at the problem of electro-optical feature fusion simultaneous interpreting the sky and sky targets from the same sensor angle, a three dimensional structure inversion method is proposed, which integrates the parameters of scattering centers and the features of contour points. Firstly, based on orthogonal matching pursuit (OMP) algorithm, the feature of two-dimensional scattering center in radar image sequence is estimated, and the corner feature of continuous visible image is extracted by Freeman chain code. Then, based on graph theory, two-dimensional feature points in radar and visible images are associated. Finally, the fusion of scattering center feature and optical corner feature is realized by three dimensional reconstruction of feature points, so as to reconstruct more abundant and accurate target structure information than single source feature. Simulation results verify the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]
