基于TM图像的人工建筑物信息提取方法探讨

Study of artificial building information's extraction based on TM image

通过对福州市TM图像资料进行几何校正和不同的增强处理 ,以监督分类和非监督分类两种方法提取人工建筑物信息 ,并与目视解译相比较。结果表明利用计算机进行自动分类在人工建筑物信息提取中也能取得好的效果。

The TM image material of Fuzhou city were emendated geometrically and enhanced differently, and the artificial building information was derived by supervised classification and unsupervised classification ,at the same time ,those information were compared with the result of translated by eyes. It indicated that computer carry on automatic to classify can make the good result in artificial building information extraction.
