摘要/Abstract

摘要： 基于高空间分辨率遥感影像获取农村建筑物的面积和分布信息,对农村基础地理数据的获取、农村土地利用规划、监测农村土地变化和居民点用地合理性评价具有重要意义。研究基于高景1号卫星影像,提出了一种基于建筑物遥感特征指数与面向对象方法的农村建筑物信息提取方法。首先构建两个建筑遥感指数对农村建筑信息进行初步提取,然后利用面向对象分割结果对初步提取结果进行优化。结果表明,该方法可以有效提取农村建筑物信息。

Abstract: Timely and accurately acquisition of the area and spatial distribution of rural building information would be valuable for acquisition of rural basic geographic data, rural land use planning, monitoring of rural land change and rationality evaluation of residential land use. Based on the Superview-1 satellite images, we propose a rural building information extraction method based on build-up remote sensing index and object-oriented image segmentation method. Firstly, we constructed two building remote sensing indexes and obtained the preliminary extraction results by threshold segmentation of the build-up index. Then the preliminary extraction results were optimized by the object-oriented segmentation results. The results showed that based on the method we proposed it can effectively extract the information of rural buildings.

Key words: object oriented image, built-up index, high resolution remote sensing image, rural building
