月球立体影像像点自动量测技术研究

Automatic Measure Technique for Image Points of Lunar Stereo Imagery

本文在分析研究多种匹配方法的基础上，针对月球三线阵CCD立体影像的像点匹配难题，分别用区域生长法和基于金字塔分层动态窗口匹配运算的相关系数法进行了试验和分析，并利用三线阵CCD数字模拟影像进行匹配，结果表明，基于金字塔分层动态窗口匹配运算的相关系数法，能够高效地解决三线阵CCD立体影像空三加密像点的自动量测。

Several existing imagery matching methods are analyzed. Aiming at the point matching of lunar three - array CCD stereo imagery, a region growing method and a correlative coefficient method based on the pyramid layer matching of moving window are respectively introduced and tested. It is shown, by using digital simulation of three - line array CCD imagery, that the correlative coefficient method based on the pyramid layer matching of moving window is effective in solving the automatic aerotriangulation pass point measure for lunar three - line array CCD imagery.
