Abstract
At present, object-extraction is one of the key problems of the data-procession to the aerial LIDAR dataset. The aim of this paper is to research the methods to classify and extract the object-points from the cloud points obtained by the aerial LIDAR system. In this paper, based on the different feature of elevation and intensity of different objects, the laser-points of buildings, vegetation and water are individually extracted. Then, several experiments are given to validate the effectivity of the object-extraction methods.
