针对无人机影像重叠度高，影像处理工作量大的特点，为了提高无人机摄影测量的工作效率，充分发挥无人机技术快速成图的优点，提出了一种利用改正后 POS数据自动展绘控制点的方法。该方法根据无人机 POS数据纠正原理，通过在区域网内布设少量控制点，建立 POS数据改正模型，从而获取 POS数据误差改正参数对原始 POS数据进行改正，利用改正后 POS数据在无人机影像上自动展绘控制点。研究结果表明，该方法对于无人机影像快速处理具有较好的实用价值。

The Unmanned Aerial Vehicle (UAV) images have the characteristics of high overlapping degree and heavy image processing workload. In order to improve the efficiency of UAV photogrammetry and take the advantages of fast mapping by the UAV technology, a method of extraction of image control points by correcting POS data was put forward. According to the principle of correct UAV POS data, POS data correction model was established and POS data error correction parameter were acquired by layout a small amount of the control points in regional network, and the corrected POS data were used in extraction of UAV images control points. The study results show that the method for UAV image rapid processing has good practical value.
