| 摘 要： | 本文根据同名像点存在的几何位置关系,提出一种利用POS数据进行像点坐标粗差检测的方法,用模拟数据验证了方法的正确性和有效性,并利用两组不同摄影比例尺的实际航摄资料进行了试验.试验表明,用该方法剔除像点坐标中的粗差后,立体像对相对定向精度得到很大提高.在保证POS数据内部相对精确的情况下,其整体系统误差对粗差检测结果没有...

| Abstract: | Based on the geometrical relation of homonymous image points,a method of gross error detection to image point coordinates using POS elements of exterior orientation was proposed in the paper.The method was verified by simulative images and tested by two kinds of different scale images.The experiments showed that gross error in image point coordinates could be detected effectively,and relative orientation accuracies of stereopairs could be improved greatly when gross errors are eliminated by this method.The ... |
