摘要
通过ERDAS IMAGINE软件二次开发,建立了一些实用的震害信息提取方法,利用这些方法开发的震害遥感信息提取的程序模块对1976年唐山地震影像、1999年台湾集集地震影像及Quickbird影像进行了处理,将得到的结果与目视解译结果进行对比,结果表明研究中提出的震害信息提取方法具有较好的实用性。
Aiming at extraction of images information during earthquake,a module is developed in this paper through ERDAS IMAGINE software-the primary software of image processing.Some practical models are established to extract information of earthquake damages by secondary development of ERDAS IMAGINE software.Aerial images of the 1976 Tangshan earthquake,IRS images of the 1999 Chi-Chi earthquake and Quickbird images are processed based on the model established in this paper.In addition,the results are compared with the results through visual interpretation,and it is indicated that this method has a good precision and robustness.
