| 摘 要： | 针对现有解算相对定向元素的公式通常用于具有相同焦距的立体像对这一现状,为充分利用不同相机所拍摄的现有影像信息,以像点坐标作为观测量,给其加入改正数,借助计算机代数系统对共面方程进行严格的线性化,推导出了适用于解算不同焦距立体像对相对定向元素的严密公式;最后,通过算例验证了该方法的正确性,可在一定程度上丰富摄影测量理论。

| Abstract: | Aiming at the status that mostly available methods for relative orientation are used for stereo images with the same focal length,in order to make full use of image information photographed by different cameras,with image point coordinates under correction,coplanarity equation is strictly linearized by computer algebra system,and strict solution for relative orientation of image pair with different focal lengths is carried out.Finally,the correctness of the formulae is verified by numerical examples.This method could enrich theories of photogrammetry to some degree. |
