摘　　要：航测数字化生产的数字地形图,其质量和精度是非常重要的。利用摄影测量的方法测图,需要一定数量的像片控制点,而控制点的布设,是影响航测精度的重要因素,测区内控制点立体、均匀地分布,及避开山谷、建筑物和电磁波干扰等因素,均有利于提高航测精度。Aerial digital production has entered mass production stage, the importance of the quality and accuracy of digital topographic maps produced by the large influx of applications is self-evident. In this paper, starting from the layout of control points, the accuracy of aerial images of various factors was researched. Measurement method using photographic mapping needs a certain number of photo control points for the correct photo of the various deviations. The result showed that the situation in the layout of control points is an important factor to the accuracy of aerial survey, the distribution and the number of control points in the survey area would be help to improve the accuracy of aerial survey.
