摘要
针对存在高大建筑物的城市区域的高分辨率遥感卫星成像模拟问题,利用3D模型作为模拟数据源,从线阵CCD高分辨率遥感卫星成像方式及特点出发,综合考虑成像时的几何变形因素影响,按照线中心投影方式对卫星遥感器进行成像模拟。最后通过实验验证了该方法是可行的,并能取得较为满意的成像模拟效果。
In order to simulate the high resolution remote sensing satellite images of the urban region with high buildings,using 3D models as data source and considering the geometrical deformation from the linear CCD imaging mode and high resolution imaging traits,a method was proposed according to the principle of line perspective.Finally,the experiment results of the simulation showed the method is feasible,and can achieve very good performance.
