DMC数码航摄区域网布点方案探讨

Different Control-point Designes in Cetain Areas Based on DMC Digital Aerial Photographic Images

相片控制测量是航空摄影测量的基础工作,传统航空摄影控制测量有成熟的作业方法和相应的技术标准和规范,而DMC航空摄影控制测量还没有制定相应的技术标准或规范,特别是在中小比例成图的应用中,更是一个空白。根据DMC航空摄影资料的特点和1:10 000地形图成图的精度要求,通过实例研究,总结区域网布点方案的规律性。

Photograph control surveying is the base work for photogrammtry.It has mature methods of operation and perfect standards and criterions for traditional photograph control surveying.So far it hasn't a corresponding standard or criterion for DMC digital aerial photographic images,in particular it's a blankness for middle and small scale map.According the peculiarities of DMC digital aerial photographic image and required precisiones of 1:10 000 scale topographical map,it summarized the control-point designe regularity in cetain areas based on instance analysis.
