Based on the principle of ortho-rectification, a theoretical estimation formula of Ortho-Rectification with no GCPs is presented, and the precision of the Ortho Rectification image with the SRTM DEM data is estimated as mentioned in this paper.Abstract:
Based on the principle of Ortho-Rectification,a theoretical estimation formula of Ortho-Rectification with no GCPs is presentedWith this formula,the precision of the Ortho-Rectification image with the SRTM DEM data is estimatedThe result shows that Ortho-Rectification Images produced by HRG image with the support of SRTM DEM have high accuracyUsing this method the DOM of Hangzhou,Chongqing and Daqing region are produced,and their accuracy are evaluated with 1∶ 10 000 topographic mapsThe results prove that the theoretical estimation formula is correct and the precision of the ortho-rectification images meets 1∶ 50 000 mapping accuracyread more
