控制点布设对航测成果精度的影响

erial digital production has entered mass production stage, digital topographic maps produced by the large influx of applications will be, the importance of quality and accuracy of its self-evident. In this paper, starting from the layout of control points, research the accuracy of aerial images of various factors. Measurement method using photographic mapping, need a certain number of photo control points for the correct photo of the various deviations, and results photogrammetry coordinate system linked with the ground, this change in a survey area or the number of control points distribution of the layout design of different mapping programs, the accuracy by comparing the different programs, analysis of aerial control points affect the accuracy factor.
