APPROACH FOR URBAN DSM EXTRACTION FROM TRI-STEREOSCOPIC SATELLITE IMAGERY

by unknown authors
"... Built-up environments are experienced as extremely complex for 3D surface modelling purposes. Main distortions that hamper 3D reconstruction from 2D imagery are image dissimilarities, concealed areas, shadows, height discontinuities and discrepancies between smooth terrain and man-made features. A m ..."

Large-Scale Dense 3D Reconstruction from Stereo Imagery

by Pablo F. Alcantarilla, Chris Beall, Frank Dellaert
"... Abstract—In this paper we propose a novel method for large-scale dense 3D reconstruction from stereo imagery. Assuming that stereo camera calibration and camera motion are known, our method is able to reconstruct accurately dense 3D models of urban environments in the form of point clouds. We take a ..."

Automatic Reconstruction of Spacecraft 3D Shape from Imagery

by Conrad Poelman Ph. D, Robert Radtke, Harry Voorhees
"... We describe a system that computes the three-dimensional (3D) shape of a spacecraft from a sequence of uncalibrated, two-dimensional images. While the mathematics of multi-view geometry is well understood, building a system that accurately recovers 3D shape from real imagery remains an art. A novel ..."

A probabilistic approach to the semantic interpretation of building facades

by O Alegre, Frank Dellaert - In Int. Workshop on Vision Techniques Applied , 2004
"... Semantically-enhanced 3D model reconstruction in urban environments is useful in a variety of applications, such as extracting metric and semantic information about buildings, visualizing the data in a way that outlines important aspects, or urban planning. We present a probabilistic image-based app ..."

3d city modeling from high-resolution satellite images

by S. Kocaman, L. Zhang, A. Gruen, D. Poli - ISPRS Workshop on Topographic Mapping from Space , 2006
"... High-resolution satellite images having a footprint smaller than 5 m are becoming increasingly available. A large number of the high resolution satellite sensors acquire imagery in a pushbroom mode with CCD linear array technology. The need for accurate 3D object reconstruction requires a sophistica ..."

Aerial 3D Reconstruction with Line-Constrained Dynamic Programming

by Huei-hung Liao, Yuping Lin, Gerard Medioni
"... Aerial imagery of an urban environment is often characterized by significant occlusions, sharp edges, and textureless regions, leading to poor 3D reconstruction using conventional multi-view stereo methods. In this paper, we propose a novel approach to 3D reconstruction of urban areas from a set of ..."

Parameter-free/Pareto-driven procedural 3D reconstruction of buildings from groundlevel sequences

by Loic Simon - In IEEE Conference on Computer Vision and Pattern Recognition (CVPR , 2012
"... In this paper we address multi-view reconstruction of ur-ban environments using 3D shape grammars. Our formula-tion expresses the solution to the problem as a shape gram-mar parse tree where both the tree and the corresponding derivation parameters are unknown. Besides the grammar constraint, the so ..."

M.: A heightmap model for efficient 3d reconstruction from street-level video

by David Gallup, Jan-michael Frahm, Marc Pollefeys, Eth Zuerich - In: 3DPVT (2010
"... This paper introduces a fast approach for automatic dense large scale 3D urban reconstruction from video. The presented system uses a novel multi-view depthmap fusion algorithm where the surface is represented by a heightmap. Whereas most other systems attempt to produce true 3D surfaces, our simpli ..."

A PROBABILISTIC APPROACH TO ROOF EXTRACTION AND RECONSTRUCTION

by S. Scholze A, T. Moons B, L. Van Gool A
"... This paper investigates into the model-based reconstruction of complex polyhedral building roofs. A set of 3D line segments, obtained from multiview correspondence analysis of high resolution colour imagery, is used as input data. The 3D line segments are grouped into planes by means of a Bayesian m ..."
