Feature matching for building extraction from multiple views

Abstract

image features. However, if we have multiple images of a In this paper we present a method to generate threedimensional building hypotheses starting from sparse features, hypothesized building corners, extracted from multiple views of the scene. This technique relies on knowledge about the imaging geometry and acquisition parameters to provide rigorous geometric constraints for the matching process. The effectiveness of this approach is demonstrated using campEex aerial imagery taken with highly obliqu: views containing buildings with flat or peaked roofs.

3-D Reconstruction of Urban Scenes from Aerial Stereo Imagery: A Focusing Strategy

“…Still these latter approaches have been mostly dedicated to the reconstruction of specific buildings: rectilinear shape [13][14][15][16], flat roof [17], or simply parameterizable shape [14,[18][19][20]. An attempt to automatically select the appropriate model has been done in [21].…”

Segmentation of Sloped Roofs from Airborne LiDAR Point Clouds Using Ridge-Based Hierarchical Decomposition

“…The plane can be defined by using the equation: (1) where is the normal vector of the plane and is the closest distance of the plane to the origin of the coordinate system. The parameters of plane are solved by an iterative process.…”

“…Most image-based approaches have focused on the reconstruction of specific building models: rectilinear shapes [1][2][3], flat roofs [4][5][6][7][8] or parametric models [9][10][11]. The image-based approach has the advantage of extracting outlines of roofs.…”

A Novel Approach for Segmentation of Airborne Laser Scanning Point Cloud Located on Roof Structure

“…Most image-based approaches have focused on the reconstruction of specific building models: rectilinear shapes (Roux and McKeown, 1994;Noronha and Nevatia, 1997;Chen et al 2004), flat roofs (Lin et al 1994;Jaynes et al 1997;Noronha and Nevatia, 2001;Shi et al 2011) or parametric models (Fischer et al, 1998;Suveg and Vosselman, 2002;Hammoudi and Dornaika, 2011). But building roofs reveal a hug variety in structure and shape.…”
