The Application Of Three-Dimensional Animation In Inertial Navigation System

This dissertation studies the 3D visualization research in Inertial navigation system(INS). There are a lot of conceptions and theories in INS, which are indigestible and abstract to students. But 3D visualization can express the abstract theories by 3D scenes, which can help teachers and students to understand.The dissertation pays more attention to the coordinate transformation, principles of gyroscope, computer graphics and 3D animation.Because the coordination transformation, the principles of single-degree-of-freedom-gyroscope and double-degree-of-freedom-gyroscope, the principles of gyroscope stationary platform in INS are precised prescribed by mathematics or dynamics equations, so we can't use the simple animation to express the principles in INS. This dissertation uses the 3D visualization models to express the INS with Visual C++and OpenGL by mathematics or dynamics equations. Because the models of airplane, missile, earth or others in INS and the relationship between them are so complex and difficult to building that we use the software of 3D Studio MAX which has the powerful ability to modeling. After building the models, we use the OpenGL to control them, because OpenGL has the strong ability to control the objects by their equations.As a result, the dissertation completes a software of 3D visualization of Inertial Navigation System named INSSystem 1.0, which can simulate the INS by 3D scenes, store the data of simulation, draw curves of simulation, store the pictures and animations with BMP, PCX, JPG and AVI file format respectively. The INSSystem 1.0 is an important part of The Innovation Plan of New Century Undergraduate Course Education, which is called Multimedia assistant education system of INS.
