DMC数码航摄区域网控制点布设方案的精度试验

Precision Experiment on Different Control-point Design in Cetain Areas Based on DMC Digital Aerial Photographic Images

介绍了DMC数码航摄影像的技术基础和其应用于航空摄影测量的优越性,鉴于DMC像幅的特殊性,在保证量测精度的前提下,为减少外业作业的工作量,通过以不同基线的区域网像片控制点布设方案的精度试验,证明了控制点按照8条基线布设完全可满足内业生产及大比例尺地形图和正射影像图的制作。

Technical basis of DMC aerial photography images and its application advantage in the aerial photography are introduced in this paper. In consideration of the particularity of the DMC format, and in order to lessen the field workload under the precondition of insuring the accuracy of surveying, through experiments on the precision of different layout schemes of photo-control points on the basis of different baselines in a certain area network, it is proved that the scheme of photo-control-point layout based on 8 baselines completely meets the inner production requirements and enable to produce the large-scale topographic maps and orthophoto maps.
