以纸质地形图或扫描地形图为工作底图,将等高线地图解译并想象为立体化地图,并充分利用各种潜在的明显地物进行地理参照和定位,是现实飞行观察技术的真实写照。为了实现所看即所得,快速定标定位,我们研究了机载电子地图制作技术。以地形图、数字地形模型和卫星影像为数据源,利用光照几何模型和视觉原理,分别制作纸质地形图的立体可视化电子图、彩色编码的立体可视化地形地貌图、正立体卫星遥感图像,解决了将等高线转换为立体地貌图,将原来的负立体卫星遥感图像表达为正立体图像的技术难题。该研究将提高飞行观察员在飞行巡护、火场侦查、火场指挥、机(索、滑)降灭火、以水灭火和空投空运、目标搜寻中的定标定位、火场标绘、导航和指挥协调的工作效率和科技水平。
Taking paper topographic maps or scanning topographic maps as the working base maps, interpreting and imagining the contour maps as three-dimensional maps and making full use of various potential and obvious features for geographical referencing and positioning are the key technologies of the real-time flight observation technology True portrayal. In order to achieve what you see is what you get, rapid calibration positioning, we studied the technology of airborne electronic map production. Using topographic map, digital terrain model and satellite imagery as data source, the three-dimensional visual electronic map of paper topographic map, three-dimensional visual topography maps of color coding and three-dimensional satellite remote sensing images are made respectively by using light geometric model and visual principle In order to transform contour lines into three-dimensional topographic maps and to express the original negative three-dimensional satellite remote sensing images as positive stereoscopic images, The study will enhance the coordination of flight observers in flight patrolling, fire detection, fire command, fire and rescue (water and fire), fire and air drop by air, positioning and calibration in target search, fire mapping, navigation and command coordination Work efficiency and technology level.
