航摄影象数字相关的一个试验

An Experiment in Digital Correlation of Photogrammetric Images

  • 摘要: 这是一篇关于航测核线影象数字相关的实验报告,主要讨论了如下几个问题;<1>从扫描系统到核线系统的影象变换;<2>通过影象预处理增强对相关有益的特征;<3>带阈值的绝对差值总和的影象匹配算法;<4>用卷积算法剔除相关结果中的粗差;<5>由地形坡度引起的影象配准误差及目标区最佳尺寸分析。

     

    Abstract: This is a report of an experiment about the epipolar digital image correlation in photogrammetry.The following problems have been described in detail:(1) Image transformation from the scanning system to the epipolar system;(2) Image preprocessing to enhance the features,which are advantageous to correlation;(3) Image matching using the sum of the absolute differences with a threshold;(4) Gross error detection by the convolution algrithm;(5) The analysis of registration error from terrain slope and the best target size.
