Automatic Building Extraction from DEMs using an Object Approach and Application to the 3D-city Modeling
نویسندگان
چکیده
In this paper, we present an automatic building extraction method based on an object approach from Digital Elevation Models. First, a rough approximation of the building footprints is realized by a method based on marked point processes: the building footprints are modeled by rectangle layouts. Then, these rectangular footprints are regularized by improving the connection between the neighboring rectangles and detecting the roof height discontinuities. The obtained building footprints are structured footprints: each element represents a specific part of an urban structure. Results are finally applied to a 3D-city modeling process.

Automatic 3d Building Reconstruction from Dems : an Application to Pleiades Simulations
This paper is about an example of PLEIADES applications, the 3D building reconstruction. The future PLEIADES satellites are especially well adapted to deal with 3D building reconstruction through the sub-metric resolution of images and its stereoscopic characteristics. We propose a fully automatic 3D-city model of dense urban areas using a parametric approach. First, a Digital Elevation Model (...

متن کاملAutomatic Extraction of Building Features from Terrestrial Laser Scanning
Realistic 3D city models are required for many purposes such as urban planning and safety analysis. The traditional modeling methods are mainly based on manual or semi-automatic reconstruction from close-range images, which are rather time-consuming. The lack of fully automatic reconstruction is mainly due to the difficulty to recover building structures from close-range images. The terrestrial...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...
