| Abstract: | A 3-D terrain matching navigation system based on Interferometric Synthetic Aperture Radar(InSAR) information is proposed, wherein the system employs a 3-D terrain matching algorithm based on 3-D Zernike moments. A new method for solving the problem of huge computation of 3-D Zernike moments in use of terrain matching and the problem of rotation adaptability is provided. In order to verify the effectiveness and the performances of the algorithm, a 3-D visual software simulation platform based on C++ and OpenSceneGraph(OSG) is constructed. Simulation results show that the 3-D terrain matching algorithm based on 3-D Zernike moments is high in positioning precision and strong in terrain adaptability, problems of real-time performance are well solved, and high practical value in engineering is obtained by the system. |
