| 摘 要： | 根据建筑物具有丰富的角点和规则的外观形状的特点，本文提出了依据线段信息生成建筑物变化检测基本单元——结构面对象的建筑物变化检测方法。从高分遥感影像中提取出建筑物的边缘线及屋顶外形线条，生成结构面对象并提取其在两时相影像中相应的特征信息，通过监督分类获取变化建筑区域。试验结果表明，利用结构面对象进行建筑物变化检测能较完整地覆盖变化建筑物表面且对象边缘检测效果较好。

| Abstract: | According to the building with rich corner points and regular appearance shape characteristics, a method of building change detection based on line segment information to generate the basic unit of building change detection—the structural surface object is proposed.The edge lines and roof contour lines of buildings are extracted from high-resolution remote sensing images,then the structural surface objects are generated and the corresponding feature information is extracted from the two-phase images. And then,we obtain the changed building area through supervised classification. The experimental results show that the use of structural surface objects for building change detection can better cover the surface of the changed building and the object edge detection effect is better. |
