Abstract: The core task of the next generation air traffic management system is to manage 4D flight trajectory of air vehicle, one of the important ways to display 4D trajectory effectively is 3D perspective projection. According to the requirements of air traffic control automation system, the rotation matrix and projection matrix of 3D space perspective projection are gotten for the new projection algorithm, and the experiment for displaying the labels of real air vehicle has been done with 3D map software. The experimental results show that the proposed algorithm is an effective 3D space perspective projection which can effectively achieve the transformation from 3D space to 2D projection plane.

Key words: air traffic control system, 4D trajectory, projection algorithm

摘要： 新一代空中交通管理系统的核心任务是对飞行器的四维航迹进行管理，而实现四维航迹有效显示的重要途径之一为三维透视投影技术。针对空管自动化系统的实际需求，求得三维空间透视投影的旋转矩阵及投影矩阵，给出一种新的投影算法，并结合三维地图软件对实际飞行器的标牌显示进行实验。实验结果表明所提出的方法可以实现三维空间到二维投影面的变换，是一种有效且可行的三维空间透视投影算法。
