影像的空间信息变化探测

Spatial-change information detection from images

为了解决影像空间信息变化探测中自动化程度和正确率均较低的问题,采用实验的方法探讨了基于属性、基于区域和基于像元的探测方法的原理,并结合专业软件ArcGIS对上述方法进行实验,取得了较好的实验结果。实验结果表明在自动发现的基础上辅以GIS、影像处理技术以及交互的方式进行信息的探测可以取得较高的探测精度和较快的探测方法。

In order to resolve the problem of lower automated degree and precision in the process of spatial-change information detection, the paper discusses the principle of approaches that are based on the feature, the region and the pixel, then conducts experiments with the special software of Arc-GIS and gets a better result, moreover the result proves that the automated discoverY with the help of GIS, image- processing technology and alternation can get much higher precision and higher speed.
