Uav Ground Station The Design And Implementation Of Visual Simulation System

Virtual scene of the UAV ground station can produce three-dimensional sight of flight data in real-time flight. Its applications of flight simulation visual using judgment and efficient flight design can be applied to real UAV visual scene, and also can be used to reduce casualties in combat missions or costs reduce. The thesis focus on real-time rendering of UAV scene and related research in the application of the UAV scene, research results used can make visual simulation figure, with this help we can make high efficiency research in the UAV visual scene.This thesis mainly reports:Presenting a visual simulation system development process, and also introduce component element that make up the whole visual system, and then the secondary development of GIS platform software for the visual design process. Base on before,3D graphics interface Direct3D-based development platform are introduced, and then give the overall system functional requirements.Do the research on three-dimensional mathematical programming theory, including conversion between three-dimensional space information and two-dimensional screen, the conversion between local coordinates and world coordinates, and so on. In order to ensure real-time UAV visual refresh rate, discuss two kind of real-time rendering of three-dimensional terrain according to the size range of area.On that basis, analysis the importance of visual applications of multi-threaded in the future, the introduction of multi-threaded engine, visual design applications. Research and design an efficient multi-threaded based on visual engine.Through analysis its working principle and related interfaces, ultimately complete an improved multi-threaded design visual design of the engine.Again, do research on the efficient visual development software named EV-Globe, and its GIS development platform API interfaces, and analyze its rendering function; this system is involved in the particle model in generating research and also space object collision algorithm. Realized function as follows:1) to achieve the effect of aircraft exhaust plume and the missile exhaust plume particles in the system.2) collision detection of space relative moving objects, if necessary, respond to the collision object "dies" and make effect change.Finally, use the application that has achieved in visual technology before, focused on two parts of tasks modules, the design autonomous flight of the UAV waypoint configuration module and module of operating to control the aircraft carrying missiles to combat test. The design of the two tasks can be applied to the waypoint configuration, rendering pipeline, aircraft flying along the pipeline control module; flight pitch, yaw and roll attitude control, model loading of aircraft, missiles, UAV viewpoint switching control model collision test results and other aspects.
