利用多尺度匹配自動套疊衛星雷達影像

Automatic Registration of Satellite SAR Image Based on Multi-Resolution Matching

摘要


合成孔徑雷達具有全天候特性,可及時監測提供災害資訊,已經成爲環境監測的重要工具。本文使用不同時期、有相同地區重疊的重複軌道拍攝之雷達影像,利用重複軌道拍攝幾何關係相似特性,像元攝像入射角度接近,在地表起伏地區,雷達影像幾何變形特徵一致,經過以多尺度匹配法爲主的處理過程,以及共軛點篩選,最後進行濾除斑駁雜訊的步驟,有效地在雷達影像上找到均勻分布且精確可靠的共軛點,進行影像自動套疊,建置衛星雷達影像自動化套疊與變遷分析,以減少人爲誤差及提昇效率。本研究成果將可提升國土監測敏感度與滿足全天候山區崩塌監測實務需求。

並列摘要


Due to its all-weather capability and stable repeat observations, synthetic aperture radar is able to provide timely information after a natural disaster. In this study, we developed a multi-scale matching technique to efficiently and effectively integrate multi-temporal for fast and accurate change detection. Experimental test results from RADARSAT and ALOS satellite radar images confirm that the proposed automatic registration scheme based on a multi-scale matching greatly reduces the artificial error and required computation, and thus is highly feasible for operational purpose.
