摘　　要：建筑物识别是地理国情监测、违法用地查处、城市快速建模的重要内容,也是各类基础地理信息数据库更新的主要任务。考虑到建筑物高突于地面的现象,以资源三号卫星提供的多光谱影像和三线阵立体观测影像为数据源,提出了基于邻域高差分析的遥感影像建筑物识别方法。以江苏省泰兴市一处城郊结合地块为研究区域进行试验,结果显示,大部分建筑物可以被快速准确地识别发现。该方法为扩展国产测绘卫星在土地资源监测等方面的应用提供了参考和技术支持。Recognition of building is an important content of national geographic conditions monitoring, illegal land use investigating and urban rapid modeling, and the main task of updating various basic geographic databases. With the multispectral image and three-line array stereoscopic observation images provided by ZY-3 satellite as the database, a new method for building identification based on adjacent height-difference analysis is proposed in view of the phenomenon that building is much higher than surrounding ground. The experiment in Taixing City, Jiangsu Province shows that majority buildings can be identified successfully. Thus this method can provide reference and technical support for expanding the application of domestic surveying and mapping in land monitoring.
