Photogrammetric refinement of laser-based building roof contours
(2013-08-15)
In this paper a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne laser scanning data. It is assumed that laser-derived planar faces of roofs are potentially accurate, while ...
Historic reconstruction of reservoir topography using contour line interpolation and Structure from Motion photogrammetry
(Taylor & Francis, 2018-09-05)
The geometry of impounded surfaces is a key tool to reservoir storage management and projection. Yet topographic data and bathymetric surveys of average-aged reservoirs may be absent for many regions worldwide. This paper ...
Extração automática de contornos de telhados usando dados de varredura a laser e campos randômicos de Markov
(2008-04-01)
This paper proposes a methodology for automatic extraction of building roof contours from a Digital Elevation Model (DEM), which is generated through the regularization of an available laser point cloud. The methodology ...
Regularization of Building Roof Boundaries from Airborne LiDAR Data Using an Iterative CD-Spline
(Mdpi, 2020-06-01)
Building boundaries play an essential role in many applications such as urban planning and production of 3D realistic views. In this context, airborne LiDAR data have been explored for the generation of digital building ...

Modeling and measuring the spatial relation "along": Regions, contours and fuzzy sets
(ELSEVIER SCI LTDOXFORD, 2012)
The analysis of spatial relations among objects in an image is an important vision problem that involves both shape analysis and structural pattern recognition. In this paper, we propose a new approach to characterize the ...
