基于多像对的近景摄影测量相机对标定

Dual camera calibration for close range photogrammetry based on multi-image pairs

本文利用共线方程进行线性变换与非线性变换的方法实现非量测型相机标定,分三步求解相机内方位元素、透镜畸变参数、外方位元素,再利用解析相对定向方法进行固定相机对的相对模型参数的标定。利用多像对相对定向得到与绝对模型大小一致的立体模型,在求解地物尺寸大小这类不需要坐标数据的应用上非常有效。

In this paper a camera calibration algorithm and the relative model parameters calibration of rooted dual camera are presented based on the method of linear and nonlinear transformation with collinearity equation.There are three steps to calculate the interior orientation elements,lens distortion parameters and exterior orientation elements of the camera.Resolve relative orientation method is utilized to get the relative model parameters.For getting the diorama which accords accurately with the absolute model through multi-image pairs relative orientation,it is very useful for the application like getting the size of objects.
