【摘要】 “无人机任务飞行的三维可视化”仿真充分吸收和运用当前先进的三维可视化理论，尽可能的模拟真三维立体显示技术的全视景、多角度、可供多人同时观察等的特点，通过四台计算机的联机，在同一时刻从各个不同的角度来显示无人机任务飞行的全过程。 文中研究了三维模型的建模技术，使用专业建模软件建立无人机、机场等复杂模型，再转化为OpenGL程序显示。在此基础上，建立和渲染整个无人机任务飞行的三维场景，使无人机的飞行环境贴近真实世界。 航迹的规划采用曲线拟合的方式。文中通过研究无人机纵向航迹跟踪和横侧向协调转弯的控制律使得无人机可以以下确的姿态沿预定的航迹飞行。为便于观察，在同一时刻从多个平面、多个角度显示无人机任务飞行的全过程。 最后，文中讨论了飞行仪表显示技术及实现仪表显示和多平面显示所必需的网间通信技术。更多还原

【Abstract】 The simulation of "Flight Mission 3D Visualization of the Unmanned Aerial Vehicle (UAV)" fully absorbs and applies current advanced 3D visualization theory, simulates the characteristics of true 3D volumetric display technique which are full-vision, multi-angle and can be observed by many persons at the same time and so on. It displays the process of flight according to mission of UAV by the online of four computers.This paper does some research of the technology of 3D modeling and uses professional software to get the complex 3D models of the UAV and airport and so on, and then transforms them into OpenGL programs. Based on this, it establishes and enriches the 3D scene, which makes the flight environment of the UAV like true world.The approach of curve fitting is used to mark out of the flight path. The UAV can fly along the scheduled fight path with correct attitude by the research of the control law of portrait flight track and transverse coordinated turn. To be convenient for being observed, the whole process of the flight according to mission of UAV is displayed from multi-plane and multi-angle at the same time.At last, the paper discusses the display technique of flight meters. To realize the display of flight meters and from multi-plane, the communication technology in network is necessarily discussed.更多还原
