Building Extraction Using Lidar Data
Accurate 3D surface models in urban areas are essential for a variety of applications, such as visualization, GIS, and mobile communications. Since manual surface reconstruction is very costly and time consuming, the development of automated algorithms is of great importance. On the other hand LIDAR data is a relatively new technology for obtaining Digital Surface Models (DSM) of the earth’s su...
متن کاملInterpolation of Lidar Data and Automatic Building Extraction
Laser scanning systems are frequently used to provide the digital surface models, DSM, of the earth surface. Laser scanning is a fast and precise technique for resampling the earth into irregular pattern. The large number of laser points hitting planar facades in urban areas facilitates the use of least-squares interpolation. In this paper some problems regarding interpolation and their solutio...
متن کاملAutomatic Extraction of Buildings from Lidar Data and Aerial Images
This paper is focused on two topics: first, it deals with a technique for the automated generation of 3D building models from directly observed LIDAR point clouds and digital aerial images, and second, it describes an object-relational technique for handling hybrid topographic data in a topographic information system. Automatic building extraction combining the mentioned data sources consists o...
متن کاملAutomated Highway Sign Extraction Using Lidar Data
1 Traffic signs are an integral element of any transportation network; however, keeping records of 2 those signs and their conditions is a tedious process, which is both time consuming and labour 3 intensive. As a result, many agencies around the world have been working towards automating the 4 process of sign collection. One form of automation is using remote sensing techniques to extract 5 tr...
متن کاملAutomatic 3D Feature Extraction from Structuralized LIDAR Data
Abstract: LIDAR, or laser scanning, is capable of collecting accurate 3D coordinates of scanned points densely and sub-randomly distributed on scanned object surfaces. The huge amount of 3D points implies abundant recessive spatial information which can be turned into dominant information through various data processing methods. To explore valuable spatial information from LIDAR data automatica...
