Abstract

Currently, a DEM (Digital Elevation Model) of high density range has been able to be created by spread of airborne laser scanner. However, when the DEM is created, the points of the DEM can not be interpolated accurately in some cases. Therefore, we propose a method of accurately interpolating the points of the DEM. The proposed method is performed by using iterative bilateral filter. Through the experiments using the DEM of 5m mesh, we demonstrate the effectiveness of our interpolation method.
