摘　　要：提出了一种基于AutoSync的快速影像配准方法,该方法采用影像子像元级的特征点自动匹配,能够高效快速精确地完成影像的纠正配准与接边。通过某市城区多张航片的纠正配准实例阐述了该方法的流程、性能优势和注意事项。说明了该方法能够极大地降低繁琐易错的人工选点工作量,提高影像配准的工作效率和配准精度,对影像间配准的自动化和批量化处理都有着重要的意义。This paper introduces a method of quick image registration based on AutoSync.The method could work very well on image registration and edge matching by using automatic point matching on image sub-pixel level.Taking many aerial photographs rectification and registration of Guang Yuan districts for an example,it explains the process flow,the performance advantages and the matters needing attention about the method.Comparing to the conventional collecting matching point by hand troublesomely,it could decrease the work time greatly,improve the work efficiency and enhance the precision of image registration highly.It is of paramount importance to research the image registration automatically and enormously in the future.
