Abstract: Aerial imaging reconnaissance is the important means to obtain tactical intelligence. This paper designs an all-time optical aerial imaging reconnaissance system for UAV referred to various flying environment. Based on UAV （Unmanned Aerial Vehicle） mathematics model, visible camera geometry imaging model and atmospheric transmission model, the system simulates the aerial camera reconnaissance using different parameters, which are changed along with UAV motion parameters, camera imaging parameters, atmospheric transferring parameters. Numbers of test results prove that the imaging reconnaissance system has very high fidelity and validity. According to output reports, system performance can be easy to evaluate and improve. More important is that this system can help guide and demonstrate aerial imaging reconnaissance equipment for UAV.

摘要： 航空成像侦察是获取战术情报的重要途径。设计的全天时可见光航空相机成像侦察系统参照无人机各种飞行环境，基于无人机数学模型、可见光相机成像几何模型和大气辐射传输模型，实现航空相机在无人机运动参数、航空相机参数、大气环境参数变化情况下的成像侦察仿真。该系统由仿真参数初始化、数字地图加载、相机成像仿真、大气辐射传输仿真、无人机半物理仿真、图像仿真与报告输出六个模块组成。通过大量实验测试表明本系统模型有很高的逼真度和有效性，同时，可根据系统仿真报告对系统模型进行性能评估与改进。本系统的参数优化功能可指导和论证无人机航空相机成像侦察装备的研制工作。
