Extraction of buildings and trees in urban environments

چکیده
In this article, two methods for data collection in urban environments are presented. The first method combines multispectral imagery and laser altimeter data in an integrated classification for the extraction of buildings, trees and grass-covered areas. The second approach uses laser data and 2D ground plan information to obtain 3D reconstructions of buildings. q 1999 Elsevier Science B.V. All rights reserved.

Automatic Detection of Buildings and Trees from Aerial Imagery Using Different Levels of Abstraction
Zusammenfassung: In diesem Beitrag wird die Extraktion von Bäumen und Gebäuden aus hochauflösenden Luftbildern und Höhendaten im städtischen Bereich beschrieben. Der vorgestellte Ansatz nutzt zur Steuerung der Szeneninterpretation verschiedene Abstraktionsebenen, ähnlich der in GIS Objektmodellen verwendeten hierarchischen Strukturierung von topographischen Objekten. Abstract: In this paper we ...
متن کاملDetection and Classification of Pole-like Objects from Mobile Laser Scanning Data of Urban Environments
− The Mobile Laser Scanning (MLS) system can acquire point clouds of urban environments including roads, buildings, trees, lamp posts etc. and enables effective mapping of them. With the spread of the MLS system, the demands for the management of roads and facilities using MLS point clouds have increased. Especially, pole-like objects (PLOs) such as lamp posts, utility poles, street signs etc. ...
متن کاملProvide a Deep Convolutional Neural Network Optimized with Morphological Filters to Map Trees in Urban Environments Using Aerial Imagery
Today, we cannot ignore the role of trees in the quality of human life, so that the earth is inconceivable for humans without the presence of trees. In addition to their natural role, urban trees are also very important in terms of visual beauty. Aerial imagery using unmanned platforms with very high spatial resolution is available today. Convolutional neural networks based deep learning method...
متن کاملExtraction 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)...
متن کاملIntegration of High Resolution Multispectral Imagery with Lidar and Ifsar Data for Urban Analysis Applications
This paper presents the integration of 50 cm 4 band (R, G, B, and infrared) imagery with 80 cm LIDAR, and 2.5 meter posting IFSAR surface elevation models for urban scene analysis. The goal is to characterize urban scenes in terms of buildings, trees, roads, other geometrical structures, open areas, and various natural land covers. This type of information is useful for applications such as urb...
