英文摘要: For the application of UAV autonomous navigation, this project will utilize the optimal esitmation theory and the Extended Kalman Filtering approach to study the following issues: the multi-rate filtering theory and approach for the fusion of indexing INS, optical flow and image matching positioning; the moving-base initial alignment theory and approach for indexing INS with the aiding of optical flow; the on-line calibration approach for inertial sensors with the aiding of potical flow and image matching positioning. Specifically, this project will mainly focus on the following problems: (1) the design, formulation, performance analysis and state reformulation of the multi-rate Kalman Filter to fuse the unsynchronized indexing INS, optical flow and image matching positioning; (2) the error model formulation of the moving-base initial alignment for indexing INS with the aiding of optical flow, and the design and analysis of the indexing scheme for the moving base initial alignment; (3) the analysis and modeling of the stochastic error elements existing in iertial sensors, and the study of the online calibration model and approach for inertial sensors. Through the above study, this project will provide a new scheme for the research and development of UAV autonomous navigation system. The successful proceeding of
