摘　　要：传统的光学遥感变化监测方法,由于需要额外的数据支持,无法消除观测系统和地形等的误差影响,且相关分析存在偏差,精度较低,操作困难,因而难以广泛应用于地表形变监测等方面。采用光学影像配准和相关性分析(Co-registration of Optically Sensed Images and Correlation,COSI-Corr)方法,无需地面控制点,可以实现影像的高精度配准和地表位移测量,且由于其广泛的适用性与较高的精度,已成为地表变形研究领域的一个热点,引起了研究者的广泛关注。本文首先探讨了COSI-Corr的技术原理和分析流程,并对该方法在大震同震位移测量、冰川变化监测、滑坡活动监测等方面的实际应用及其优点进行了详细介绍。最后讨论了该方法应用中的关键问题和发展前景。研究表明:光学影像配准和相关性分析方法(COSI-Corr)操作简单、效率高、分辨率高达1/10像素,可用的遥感影像数据多,并且可以应用于LiDAR差分研究中,与InSAR具有互补性,该方法可以广泛地应用在地表形变监测当中。Traditional optical remote sensing change detection methods can’t eliminate the error induced by the imaging system and terrain,due to the need for external information from global positioning system(GPS)measurements.And these methods have low measuring precision,biased correlation techniques,implementation difficulties,cannot be applied to monitor surface deformation widely.Co-registration of Optically Sensed Images and Correlation(COSI-Corr)software accurately co-registers images,measures local displacements,and does not require ground control points.COSI-Corr has become a hot spot in the field of surface deformation because of its wide applicability and high accuracy.We discuss the principles and process of analysis of COSI-Corr and introduce some applications of the technique,such as coseismic deformation measurement,the glacier change monitoring,monitoring of landslide activities.We describe the advantages of COSI-Corr.Finally,key problems with COSI-Corr application and its prospects are discussed.We show that COSI-Corr is an efficient and versatile tool.Its accuracy is higher than 1/10 of the pixel size.Additionally,the availability of high-quality optical satellite images is increasing.This approach can be applied to LiDAR and is complementary to InSAR.COSI-Corr method can be widely used to monitor surface deformation.
