小比例尺航片制作正射影像的方法研究

The Methods of Small Scale Aerial Photo Manufacture Digital Orthophoto Map

利用1:50000～1:60000航片制作1:10000正射影像的实验性方法正处于研究阶段.探讨了在实验中保证正射影像精度的实施方案,如DEM数据采集和影像镶嵌、匀色的关键技术的解决方法.对利用1:50000～1:60000航片制作1:10000正射影像的关键问题进行了分析,并提出了解决方案.

Using 1：50000-1：60000 aerial photos to make 1：10000 orthophotos is in a phase of experiment. This paper discusses the implementation plan of guaranteed orthophotos projection precision in the experiment, such as DEM data acquisition and images mosaic, uniform color of the key technologies implemented. Furthermore, it probes into the key technology to make 1：10000 orthophotos projection by using 1：50000-1：60000 aerial photos, and then puts forward solutions.
