| 摘 要： | 分析了影响自然环境和人造建筑航空成像的各种因素，按照大气传输的基本规律，建立了数字景像匹配图模拟生成的数学模型，提出了仿真系统研制的设计方案。针对图像增强型CCD相机，研究了其成像机理，完成了基于大气软件LOWTRAN-7计算内核的成像仿真系统的研制。利用数字高程数据、场景表面的材料库、气候信息和实体几何模型，该系统可对成像过程进行基于图像的动态仿真，并可大量模拟不同气候下的景像匹配图。

| Abstract: | Most factors affecting aviation imaging of natural environment and cultural characteristics was analyzed. Mathematical model of digital scene image synthesis was established according to the essential principles of atmosphere transporting and a design framework for the simulation system was proposed. Aviation imaging mechanism oriented to image intensified CCD camera was studied and an aviation imaging simulation system was developed using the computing kernel of LOWTRAN-7. Using digital elevation map(DEM), geometry model with material and weather information, the system can simulate the imaging process dynamically and various digital scene images can be generated under different weather conditions. |
