title = "Vegetation extraction from LiDAR raw points using surface flatness",
abstract = "Removal of vegetation and buildings is a very important task for DEM (Digital Elevation Model) generation from LiDAR data. In this paper we consider the problem of tree removal. To achieve this task we used surface flatness. The flatness of a 3D object modeled by a set of points is defined as its volumetric surface divided by its surface projected on 2D. Trees tend to have higher flatness values than other objects. In order to determine the exact boundaries of the trees, the flatness map is used as initialization mask for the active contour algorithm. We successfully detected about 80% of the trees.",
