基于数字摄影测量的战场地形信息快速获取

Fast Achieving Battlefield Landform Information Based on Digital Photo Measurement

战场地形信息基于数字摄影测量快速获取。通过解析共线条件方程式,利用相对定向直接法进行像对的相对定向。由于畸变改正及相对定向后模型仍存在变形,按最小二乘法原理,采用数学中多项式逼近的方法进行模型的非线性改正。然后进行绝对定向,求得各模型点的空间绝对坐标。最后通过一实例证明了方法的可行性。

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.
