摘要：In recent years the research activity in image registration has grown at the same pace as the high resolution satellite images have found their way to end users. Much of this research activity has concentrated on methods improving the accuracy of georeferencing provided as RPC values. In this study the image registration via projective transformation based on straight line segments is investigated. The transformation parameters are solved based on real data extracted from topographic database and measurements done on QuickBird image. Same data is processed also with point wise method and accuracy numbers in selected check points are calculated. The RMS values computed in same check points prove that with the line based method the equivalent accuracy can be achieved as with the point wise method computed with minimum number of observations. In a smaller sub image the accuracy of transformation with line segments could be verified to be in size of a pixel
