摘要
针对当前机载数据处理以数据分析和二维图表为主,而现有飞行回放可视化上架软件成本过高的现状,为在普通PC上直观再现飞行过程,提出并建立了三维场景的飞行回放。该系统根据视点位置实时读取、渲染和显示不同地形块,根据飞机的高度选择不同精度的地形数据模型,解决了高原机场周边山地大规模地理信息数据与计算机实时处理能力的矛盾,实现了逼真、流畅的飞行回放。仿真实验结果表明,该系统飞行回放仿真动画速度到达20帧以上,能直观反映飞行状态,且成本低,对飞行事后分析具有重要参考价值。
Data analysis and chart are main method for airborne data processing today and cost of software production of visualized flight playback is unacceptable for most airlines. For flight course visual reappearauce in PC, flight playback system is provided. Reading, romancing and displaying pitches is based on eyes position and precision of pitches is based on airplane height. Confliction between large-scale geographic information data surrounding of plateau airport and real-time calculation capability limitation of computer is solve＆ Verisimilitude and smooth flight playback is achieved. Simulation experiment indicates that system speed is more than 20 FPS and flight state can be reflected visible and it has important reference value for analysis after flight.
