摘要:
运用GIS提供的先验知识对遥感立体像对进行三维变化检测。首先,利用GIS提供的控制数据(DOM 和DLG)辅助解算新立体像对外方位元素;其次,使用GIS数据库中DOM 和DEM 提供的物方参照进行多视平面扫描密集匹配;第三,将生成的新DEM 与旧DEM 比对,检测出三维变化。对汶川映秀的航空遥感立体像对进行实验,验证了本方法的可行性。
摘要(英文):
3D change detection is implemented by new epoch remotely sensed stereo pair with old epoch GIS-aided data that can provide information as prior knowledge. Firstly, exterior orientation elements of stereo pair are solved by control data supported by old epoch GIS data (DOM and DLG). Secondly, on the basis of a plane sweep method, dense multi-view matching is realized by object reference aided by a DOM and DEM. Thirdly, 3D change detection is carried out by subtracting an old epoch DEM from a new epoch DEM generated by above dense image matching. Finally, for remotely sensed aerial images of Wen...
