| 摘 要： | 文章提出了一种INSAR复数影像自动配准方法,该方法包括重叠景区概略配准、像素级粗匹配、亚像素级精匹配三个环节。为了提高匹配的效率并发现和消除误匹配,在粗匹配时采用了伪金字塔影像分频道相关和回归分析法检验相结合的算法。通过对几景ERS-1/2 SAR影像数据的试验,证明该方法具有良好的性能,对INSAR数据的规模化应用具有实际意义。文中还对常用的亚像素级匹配算法的性能和最小二乘匹配法对复数影像配准的有效性等进行了分析。

| Abstract: | The paper proposes one multi-step registration procedure for interferometric synthetic aperture radar(INSAR)complex image.The procedure includes calculating the approximate offsets,pixel level's primary match and sub-pixel level's precise co-registration.To achieve high efficiency and find out and remove false matching,a combining algorithm between multi-channel correlation and the constraints tie points are employed during pyramid image primary match.The hereinbefore procedure is proved to be fine reliability and is better to satisfy the demands of large-scale INSAR processing through processing several image pairs collected by ERS-1/2.Further more,several widely used sub-pixel image matching and the least square image matching method's effectiveness for complex image has been analyzed too. |
