3D reconstruction of generic house roofs from aerial images of urban areas

摘要: A method is presented to automatically generate 3D models of house roofs from aerial images residential areas in urban sites. First, homogeneus regions with consistent photometric and chromatic properties corresponding roof structures are delineated the by navigating through a constraint triangulation network. Stereo matching straight line segments performed between only. Line that matched across at least three views reconstructed bundle adjustment procedure. The then grouped into coplanar configurations polygonal patch hypotheses formed. Subsequently, each polygon hypothesis subjected consistency verification respect reconstruction original image data, and, if necessary, corrected accordingly. Observe combinatorics kept under control processing one region time. In next stage, polygons glued together model. emphasis here on extracting correct topology structure. Metric accuracy obtained an additional step backprojecting recovered (wireframe) model structure onto minimizing total reprojection error. viability this approach has been tested state-of-the-art dataset Brussels.
