摘要
相机的外方位元素是摄影测量立体重建的重要参数。通过3维直接线性变换,利用3维控制场可以很容易地确定相机的外方位元素。文中提出并推导了在2维控制场的条件下,利用2维直接线性变换和共线方程之间的关系分解出相机外方位元素的实用算法。实验结果验证了该算法的正确性和可行性。
Camera＇s exterior orientation elements are important parameters for photogrammetry stereo reconstruction. It is easy to determine these parameters by 3D direct linear transformation using known 3D control fields. In this paper, we proposed and deduced a novel method for decomposing the camera＇ s exterior elements using the relation between 2D direct linear transformation and collinearity equation. Test results demonstrated this method is true and feasible.
