Abstract

A Method for extracting buildings and houses from high density elevation data obtained by a scanning laser ranging instrument carried on a helicopter has been developed by applying region segmentation to the elevation data. Boundary data of building polygons are obtained from the labeled images. With this method, building data for digital map data can be generated through automatic processing of the laser scanner data in principle, although the results show deformation due to remaining positioning errors in the original data.
