  • 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.
