摘要
交会定点是测绘中一种主要的数据获取方式,影像交会定点是摄影测量的基础。若已知影像的6个外方位元素便可确定被摄物体与影像之间的关系,进而由立体像对空间前方交会法解算出同名像点在物方空间坐标系中的坐标。为此,论文采用C#编程技术,借助计算机强大的计算能力,实现像点坐标的量测以及数字影像外方位元素的解算,最终根据量测出的同名像点像坐标及其外方位元素解算出所对应地面点的地面坐标。
The intersection point is one of the main data acquisition methods in surveying and mapping, and the intersection point of images is the basis of photogrammetry. If the 6 outer elements of the image are known, the relation between the object and the image can be determined, and then the coordinate of the image point in the object space coordinate system is solved by the stereo intersection method. Therefore, this paper adopts C# programming technology, using the powerful computing capability of computer, realizes the image coordinate measurement and azimuth digital image elements according to the final solution, measures the corresponding image points like coordinates and exterior orientation elements are calculated corresponding to the ground coordinates of ground points.
