基于高分辨率遥感影像的农村聚落信息的提取

Extracting the Rural Residential Information From High Resolution Satellite Imagery

传统的房屋提取方法一般基于像素的提取,无法利用影像的空间信息。本文提出了一种面向对象的卫星影像房屋提取方法。利用影像对象的光谱特征、几何特征和空间关系建立知识库,利用知识库中的规则来提取影像中的房屋。

Extraction ofthe housing generally based on the extraction pixels, unable to spatial information ofimages. This paper presents a object-oriented high resolution satellite images extraction housing methods, get image objects from image segmentation and then through analysis housing characteristics of the QuickBird images, using the spectral characteristics, geometry and spatial characteristics of image objects to establish the knowledge database, use the rules of the knowledge database to extract housing from images.
