Fast Achieving Battlefield Landform Information Based on Digital Photo Measurement

The quickly achieving battlefield landform information is based on digital Photogrammetry. By analyzing collinear equation and adopting absolute orientation method,the stereo pair of photos is relatively oriented. Because of distortions after aberrations’ being corrected and relative orientation,models are non-linear corrected with polynomial approached method from mathematics,according to least square theory. Then,models are absolutely oriented,achieving special absolute coordinate of models. According to an example,it approved that this method is feasible.
