Reconstructing Tree Crowns from Laser Scanner Data for Feature Extraction
The objective of this study was to carry out reconstruction of single tree crowns from laser scanner data to use the obtained vector model for feature extraction. The reconstruction was implemented in several stages. First, pulses which have reflected from each tree were marked off from the original point cloud. Ground points were then separated from all points using digital terrain model and a...
متن کاملA Research for the Extraction of 3D Urban Building By Using Airborne Laser Scanner Data
This paper will focus on the extraction of 3D urban building from ALS (Airborne Laser Scanner) data in built-up areas with the incorporation of GIS data . Sample terrain points are firstly captured by the integration of normalized DMS data and GIS road network data. Rough DEM is interpolated from the sample terrain points, which make it possible to extract potential building by subtracting from...
متن کاملApplication of Airborne Laser Scanner
This dissertation explores the use of an Airborne Laser Scanner (ALS) for various types of aircraft Terrain-Referenced Navigation (TRN) techniques. Using the methods explored, an ALS-based TERRain Aided Inertial Navigator (TERRAIN) was developed, flight tested, and shown capable of providing meter-level positioning accuracy in real-time. The ALS-based TRN techniques discussed are constrained to...
متن کاملUsing Airborne Laser Scanner Data in Forestry Management: a Novel Approach to Single Tree Delineation
Lately, laser scanning even of huge areas has become economically sensible due to new airborne laser-scanners delivering higher resolutions and measurement frequency. In this paper we will describe a novel approach for single tree delineation based on airborne laser-scanner-data for use in forestry applications. This currently leads into the development a forestry management tool as a part of a...
متن کاملExtension of an Automatic Building Extraction Technique to Airborne Laser Scanner Data Containing Damaged Buildings
Airborne laser scanning systems generate 3-dimensional point clouds of high density and irregular spacing. These data consist of multiple returns coming from terrain, buildings, and vegetation. The major difficulty is the extraction of object categories, usually buildings. In the field of disaster management, the detection of building damages plays an important role. Therefore, the question ari...
