摘要：Reconstruction from a single view of architectural scenes is possible thanks to the automatic identification of structural perspective elements in the view. Reliable and accurate reconstruction depends strongly on a robust estimation of vanishing points. In this paper we compare different approaches for estimation of vanishing points, and we justify our choice of Danish estimator. The intersection of pairs of pencils of perspective lines through vanishing points generates maps of quadrilaterals in the image which provide automatic grouping criteria for interpreting the scene. Quadrilaterals are not enough for an accurate reconstruction. Triplets of pencils of perspective lines provide a wire-framed structure of traditional architectonic scenes used for visualization tasks by constructing trapezoidal and cuboid maps superimposed to views with a low computational cost. By identifying multiple junctions in images we obtain the relative orientation between adjacent planes containing bundles of perspective lines. The introduction of multivector representation simplifies the visualization and management of 3D information arising from the lifting of adjacent quadrilaterals to 3D cuboids for visualization tasks
