- Abstract:
- Taking earthquake sites in the old county town of Beichuan as research area,the nDSM data of the height information of the building. in the study area are obtained by using the point cloud CSF filtering algorithm. The slope characteristic of the building is obtained through the points cloud grid processing and the slope value calculation. Combine the DOM and nDSM and slope image of the research area,we extract the seismic damage of building through the object-oriented method. The results show that the method of combine DOM and height and slope information can improve the extraction the accuracy of building damage than only use DOM.
