中文摘要：

高空间分辨率全色遥感图像在军事侦察、地面监视等领域具有较高的应用价值.为模拟星载全色遥感图像,提出了一种由艇载遥感成像系统获取的低空遥感图像为数据源的高空间分辨率全色遥感图像仿真方法.首先将低空宽视场图像按典型地物类型进行监督分类,其次将低空宽视场图像与多光谱图像按不同地物类型分类拟合,并将多光谱拟合结果合成高空间分辨率全色仿真图像,最后对高空间分辨率全色仿真图像进行仿真精度评价.相比星载全色遥感图像,仿真图像同样具备高空间分辨率、全色波段、宽视场等特点.仿真方法可为星载全色遥感图像仿真提供较准确的数据支撑.

英文摘要：

Panchromatic remote sensing image with high spatial resolution has been applied in military reconnaissance, ground surveillance and other areas. A simulation method for high spatial resolution panchromatic remote sensing image is presented. The data source of the simulation is a kind of the airship remote sensing image. The low-altitude wide-field images were classified according to typical surface features. Then these images and the multi-spectral images were fitted to different typical features. The high spatial resolution panchromatic simulation image was composed by the fitting re- sults. The simulation precision was assessed. Compared with satellite panchromatic remote sensing images, high spatial resolution panchromatic simulation image has the same spatial resolution, panchromatic band, wide view and so on. This method provides accurate data source for the satellite panchromatic remote sensing image simulation.
