摘　　要：为分析飞行数据是否满足飞行性能要求,观测飞行过程中制导弹药部件间的相对运动,应用FlightGear飞行模拟平台,研究了制导弹药三维模型建模方法、可视化场景绘制技术、飞行实测数据的处理方法和三维模型的实测数据驱动技术,构建了制导弹药飞行实测数据驱动的数据可视化系统,实现了制导弹药飞行过程的多视角可视化,直观再现了制导弹药飞行过程中的飞行轨迹以及不同部件之间的相对运动关系,为判断制导弹药飞行数据有效性和飞行控制过程等提供了可视的技术手段。In order to analyze if the flight-test data to satisfy the performance requirements of flight,and to observe the relative motions between guided munition parts during the course of flight,by use of FlightGear flight simulation platform,the guided munition modeling method of 3D model,the rendering method of virtual scene,the processing method of flight-test data and the measured data driven technology of 3D model were studied,and the visualization system of flight measured data of guided munition was constructed to realize multi-angle of view visualization during the course of flight of guided munition.This method can intuitively reappear the flight path of guided munition during the course of flight and relative motion between various parts,and it can provide visualization technological means for j udging the flight data validity of the guided munition and flight control process.
