Abstract

With the aerial LIDAR technology developing, how to automatically recognize and reconstruct the buildings from LIDAR dataset is an important research topic along with the widespread applications of LIDAR data in city modeling, urban planning, etc.. Applying the information of the first-and-last echo data of the same laser point, in this paper, a scheme of 3D-reconstruction of simple building has been presented, which mainly include the following steps: the recognition of non-boundary building points and boundary building points and the generation of each building-point-cluster; the localization of the boundary of each building; the detection of the planes included in each cluster and the reconstruction of building in 3D form. Through experiment, it can be proved that for the LIDAR data with first-and-last echo information the scheme can effectively and efficiently 3D-reconstruct simple buildings, such as flat and gabled buildings.
