Extraction of Building Ground Plans from Lidar Data
The goal of this research is to extract and delineate building ground plans from LIDAR data. Our approach consists of three steps: first of all, the raw point cloud has to be classified into terrain points and off-terrain points. Secondly, the off-terrain points (the potential buildings) have to be aggregated to form connected building blobs. Those blobs that exceed a certain size and have cert...
متن کاملFeatures and Ground Automatic Extraction from Airborne Lidar Data
The aim of the research has been the developing and implementing an algorithm for automated extraction of features from LIDAR scenes with varying terrain and coverage types. This applies the moment of third order (Skweness) and fourth order (Kurtosis). While the first has been applied in order to produce an initial filtering and data classification, the second, through the introduction of the w...

متن کاملDEM Development from Ground-Based LiDAR Data: A Method to Remove Non-Surface Objects
Topography and land cover characteristics can have significant effects on infiltration, runoff, and erosion processes on watersheds. The ability to model the timing and routing of surface water and erosion is affected by the resolution of the digital elevation model (DEM). High resolution ground-based Light Detecting and Ranging (LiDAR) technology can be used to collect detailed topographic and...
متن کاملClustering Based Planar Roof Extraction from Lidar Data
An approach to generate 3-D models of buildings from lidar data collected from an urban setting is presented. The present research focuses on extracting roof structures from a point cloud of a building using a combination of datamining techniques. To extract the roof structure, an assumption of planarity has been made, i.e. it is assumed that the roof can be modeled by a set of planar segments....
