摘　　要：三维地理信息系统可以为用户提供直观的二维或三维可视化模拟场景,火箭地面安控系统通过设置合理的安全管道,实现对火箭飞行过程中的安全控制。针对火箭飞行过程中安全控制工作和对飞行态势信息的精细化显示及判决要求,将三维地理信息系统应用于火箭安控态势判决,使三维地理信息系统接收火箭实时飞行数据,全程展示火箭飞行态势,通过研究实现坐标系间转换算法和三维空间内对象碰撞检测算法,实时精细化地计算和显示火箭与三维空间安全管道的位置关系,为安控指挥员提供直观精准的可视化场景和自动化的安控态势决策结果,从而开展及时、准确的地面安控判决与实施,实现对地面目标最大程度的安全保护。The three-dimensional(3D)geographic information system can provide users with intuitive twodimensional(2D)or 3D visual simulation scenes.The rocket ground safety control system can achieve the safety control during rocket flight by setting reasonable safety pipelines.In response to the safety control work during rocket flight and the requirements for fine display and judgment of flight situation information,the 3D geographic information system is applied to the rocket safety control situation judgments,allowing the 3D geographic information system to receive the rocket’s real-time flight data and display the rocket’s flight situation throughout the entire process.The coordinate system conversion algorithm and the object collision detection algorithm in 3D space are investigated and implemented to calculate and display the position relationship between the rocket and 3D safety pipelines in real time,by which the intuitive and accurate visualization scenes and automated safety control situation decision-making results are achieved.With the information,the safety control commander can carry out timely and accurate ground safety control judgments and implementation,and achieve the maximum safety protection for ground targets.
