The Method And Realization Of Image Navigation

Using Remote Sensing Image in the Navigation field is the hotspot at present which can provide ampler,more intuitionistic and more visual information of geographical space,navigation and orientation .This dissertation does the research in the application of Remote Sensing Image in the Navigation field, The main work and innovations are as follows:Firstly, the basic concepts and some characters of Image Navigation are analyzed in detail, the domestic and overseas present researching conditions of Image Navigation are Enumerated . Then,the dissertation indicates current existent key problems in Image Navigation ,and the reasonable organization of the Image Navigation data,the usage strategy of data in Navigation and how to fuse Navigation datas effectively are analyzed.Secondly, the key techniques of the Image Navigation are analyzed according to the characters of the Image Navigation,which mainly includes the data organization and management technique of the Image Navigation,the usage strategy of Navigation data and the method of the Multi-source Navigation data's fusion.Thirdly, the organization method of the Remote Sensing Image in the Image Navigation is analyzed, proposing the theories of Data organizition that can be adapted to Image Navigation; Conducting a detailed analysis on the organization strategy of vector data in the meantime;Using homologous Navigation strategy according to different driving environments, which adequately develope the respective advantages of vector map and Remote Sensing Image.Fourthly, the thought of data fusion in the Image Navigation is introduced, and propose the fusing methods to three kinds of Navigation datas (running tracks, Remote Sensing Image and vector map), then, introduce the Marchal's map matching algorithm and Genetic algorithm. In order to solve the shortcomings of both algorithms, the dissertation puts forward improved Marchal's algorithm and Distance-angle Fitting algorithm, and makes some experiments to carry on a verification.Fifthly, based on the above theories, Image Navigation system software is developed, and the developing environment and navigation function are introduced in detail. Besides, the dissertation explores the development of Image Navigation system in embedded device. Then , Analyzes secondary development theorieses of GoogleEarth and GoogleMaps, and carries on a verification to the theories of Image Navigation using of the high resolution images that both provide.
