Analytical deformation on aerial photographs by using digital photogrammetric applications

Abstract

Deformation is a change in the position of a point on aerial photographs, map, manuscript or print from its originally plotted position. This change is the result of differential shrinkage and /or expansion of the film or paper or lens sensitivity of the cameras and/or the positions of projectors during operation. There are many methods used before to solve this problem such as resection intersection method, and rotation coordinates method. The research aim to analysis the deformation on aerial photographs and show the ablates how to use application of digital photogrammetric to the measurement of deformation , also two different approaches method of stereomodels with control, multi station photogrammetry. Are identified and compared, references to and summaries of recent work are made. And show the result which be attached .it will be strongly recommended that to use the first method because it is easy, quick and cost lower money than the second one by practical, but still the second one more accurate in the result .
