三线阵CCD影像的像点自动匹配技术研究

目前国内针对三线阵CCD影像像点自动量测技术研究比较少,主要采用常规影像匹配方法进行处理。本文在分析众多匹配方法的基础上,根据三线阵CCD影像的特点,在立体环境下对三线阵CCD影像空三加密像点自动量测的方法进行研究。用实验的方法研究了基于金字塔分层动态窗口匹配运算的相关系数法在三线阵CCD影像像点立体匹配中的应用,最后通过三线阵CCD数字模拟影像试验,得出结论:采用金字塔分层动态窗口匹配运算的相关系数法是解决三线阵CCD影像空三加密像点自动量测问题比较有效的途径。

Study of automatic matching technology of image points for three line array CCD imaging

Currently,only a few of researches on automatic measurement technology for three line array image points are developed in China,and the method principally employed is regular image matching technology.According to the characteristics of three line array CCD imaging,the automatic triangulation method of pass points for three line array CCD imaging is studied in stereo environment depending on comparison of various matching methods.Then,correlation coefficient method which is grounded on pyramid layer dynamic window matching applied to pass points matching in stereo environment for three line array CCD imaging is analyzed in experiments.In the end,the experimental results indicate that correlation coefficient method based on pyramid layer dynamic window matching is relatively effective in resolving problems in automatic triangulation of pass points for three line array CCD Imaging by carrying on digital simulation experiments for three line array CCD imaging.
