中文摘要：

提出一种利用相机POS数据和少量影像数据标定倾斜相机间位置关系并计算倾斜影像粗略外方位元素的方法。首先对选取的垂直和倾斜影像进行影像匹配,获得精确同名点坐标;然后垂直影像同名点对前方交会获得地面点坐标,接着倾斜影像后方交会获得其外方位元素;最后利用倾斜和垂直影像的外方位元素标定子相机间的相对关系,并根据相对关系求出所有倾斜影像的外方位元素。采用AMC580倾斜影像数据进行试验,结果表明：提出方法可求得所有倾斜影像的粗略外方位元素,并验证了外方位元素的直接对地定位精度,证明了该方法的可行性。

英文摘要：

This paper proposes a method of using the POS data and a few images data to calibrate position relationship between tilted cameras and calculate the rough exterior orientation elements of oblique images. Firstly, the nadir and oblique images are matched to obtain accurate match points. Secondly, the ground coordinates are obtained by intersection of nadir images, and then the resection is executed for oblique images to gain the exterior orientation elements. Finally, the relative relationship between sub-cameras is calibrated by using the exterior orientation elements of oblique images and nadir images, and the exterior orientation elements of oblique images are determined according to the relative relationship. In the paper, AMC580 oblique images data are tested. Experimental result shows that the method is feasible, the direct geo-referencing accuracy of the exterior orientation elements for oblique images is considerably higher after refinement, which indicates that the feasibility of this method is proved.
