摘　　要：对研制的近地超轻型小数码航空摄影测量系统进行介绍并对其在焦作市的应用进行分析.该系统总体由4部分组成:超轻型飞机飞行平台;数码影像获取系统;数据处理软件系统;地面辅助系统.其关键技术包括:系列数码航空摄影测量仪;非量测数码相机的高精度检校技术;稳定平台与航飞相机姿态控制技术;GPS定点曝光和实时补拍技术;虚拟相片制作技术及真彩影像;高精度单点定位在航测中的应用;高精度大比例尺测图;超轻型飞行平台(飞机)的改造及影像数据后处理技术.在焦作市大比例尺测图中的应用表明,本系统航飞适应性强,地面野外工作量少,航测成本低,成图周期短.总之,该国产数码航测系统的研制成功,将给我国测绘工作带来一场新的变革.A close - to - earth digital aerophotogrammetry system with over - light plane is introduced, and its application in Jiaozuo is analyzed. The system has four parts, which including overlight plane, obtaining system of digital images, software system of data handling and ground - aid system. The key techniques are series of digital aerophotogrammetry instruments, high - precise check - up technique, stable fiat and control technique of camera pose in flying, GPS point - fixed exposal and temporal photo - taking for compensating, virtual picture - processing and real color images, the application of high - precise single point positioning in digital aerophotogrammetry, high -precise surveying and mapping in large scales, the reconstruction of plane and image data post- handling. The application to surveying and mapping in large scales of Jiaozuo indicates that the system has very strong adaptability to flying, less fieldwork, lower running costs and shorter period to get maps. The success of digital aerophotogrammetry system made in China will bring us a new transforming for surveying and mapping cause.
