| 摘 要： | 本文主要讨论1:1.6万航空像片测制1:2000地形图时,用交会法测定像控点的精度问题.按现行规范的规定不能满足1:2000测图精度要求。为保证连测的像控点精度的可靠性,本文提出了按交会基线长度和交会图形强度,增加适当测回数,提高测角精度的方法。

| Abstract: | This paper mainly deals with precision of photog- raph control points by intersection method in the survey of 1:2000 topoqraphical maps with 1:16000 aerial survey photographs.The determination of the present stipulations of surveying specifications can not meet the needed precision in surveying 1:2000 topographical map.To ensure the reliability of the precision of photograph control points by continual survey,a method is recommended that increases the appropriate numbers of the observation set and promotes the angle measurement accuracy according to the length of intersection base lines and the intensity of intersection figures. |
