Extracting Buildings from Digital Surface Models

چکیده
This paper describes an approach for building extraction using Digital Surface Models (DSM) as input data. The first task is the detection of areas within the DSM which describe buildings. The second task is the reconstruction of buildings for which we apply parametric and prismatic building models. The main focus is on the detection, namely on the use of height and differential geometric information to discriminate building and vegetation areas. Furthermore, recent results for the extraction of roof structures as first step towards the extraction of polyhedral building descriptions are presented.

Extraction of Different Buildings from Lidar Data
Airborne laser scanning has become an arch technology and which is now widely accepted for 3D data collection. These 3D points represent the terrain surface as well as objects on top of the terrain surface. Airborne LIDAR systems are able to record data through multiple pulses which make the data very accurate. LIDAR data is a relatively new technology for obtaining Digital Surface Models (DSM)...

The classification of land use, degree of development, and the location of major features, such as buildings and expanses of vegetation are of considerable interest to planning bodies, relief agencies, and the military. Landscape characteristics are under continuous modification, especially in urban and suburban areas, and therefore the maps of these areas need regular updating. Derived databas...
