遥感影像匹配技术在地震形变监测中的应用研究

Research on Application of Remote Sensing Image Matching Technology in Earthquake Deformation Monitoring

针对传统地面观测技术、GPS技术和D-InSAR技术在地震形变监测中的不足,提出将遥感影像匹配技术用于地震形变监测的命题。分析了光学影像匹配技术的基本原理和实施方法,并将该技术应用于美国加利福尼亚州赫克托矿区域的Mw7.1级地震的形变监测。实验证明,该技术所监测的断层位置和地表破裂等与野外调查的结果基本吻合。

Aiming at the defects of traditional ground observation technology, GPS technology and D-InSAR technology in earthquake deformation monitoring, it puts forward the application of sensing image matching technology to earthquake deformation monitoring. It analyzes the basic principle and implementation method of optical image matching technology and uses this technology to the Mw 7.1 earthquake deformation monitoring of the Hector mine area in California of America. The test shows that these monitoring results of fault location and surface rupture are basically consistent with?field investigation ones.
