铅垂线辅助的大比例尺城区空三自动转点

Vertical Lines Supported Tie Points Auto Extraction of Large Scale Aerial Triangulation Over Urban Areas

  • 摘要: 利用城区航空影像中存在的大量铅垂线,提出了一种铅垂线辅助的多影像匹配算法。该算法应用于大比例尺城区的空三自动转点,大大提高了自动转点的成功率。

     

    Abstract: Auto matching of the large scale aerial imagery over urban areas is one of the most difficult problems in the auto aertial triangulation.Through the analysis of the auto-extracting tie points strategy of VirtuoZo AAT,the vertical line observations in the large scale aerial imagery over urbans have been introduced into the traditional continuous relative orientation;and then a multi-image matching strategy with the correction of geometric distortion in the images due to the height variance has been prompted to improve the success rate of the auto-matching of images between strips.
