应用单张像片解析法实现测绘图像实时定位

REAL-TIME LOCATION DETERMINATION OF MAPPING IMAGE USING SINGLE PHOTO ANALYTIC METHOD

针对某大地测绘系统 ,根据空中探测器实际位置和姿态确定测绘图像的 6个外方位元素 ,结合摄像机的 3个内方位元素和选中点在图像上的位置 ,应用单张像片解析法 ,可以求得图像上任意点的地面坐标 ,最后经过变换给出该点的经纬度 ,解决了测绘图像实时定位问题。

Aimed at a certain earth mapping system, six outside orientation elements are determined based on the actual location and attitude of the detector, and the ground coordinates of any point in mapping image are calculated using a single photo analytic method, based on three inside orientation elements of vidicon and location of the point in the image. Finally, the longitude and latitude of the point are given by exchange. The problem of real time location determination of mapping pictures is solved.
