SWDC数码航摄区域网控制点布设的精度试验

Precision Tests of Different Control-points Design Schemes in a Cetain Area Based on SWDC Digital Aerial Photography Image

摘要:

介绍了SWDC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SWDC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条基线布设可满足内业生产及大比例尺地形图的需要。

Abstract:

This paper mainly introduces the technical basis of the SWDC aerial photography image. Because of the particular property of the SWDC format, under the premise for ensuring the accuracy of measurement, in order to reduce the workload of operations outside, through precision tests of points laid by a regional network in a different photograp of the baseline, it is proved that the control points in accordance with 8 baselines emplaced within the industry can meet the production need for large-scale topographic maps.
