Fig. 4From: Data completion in building information management: electrical lines from range scans and photographsGrammar based building façade reconstruction. A grammar that specifies a simple variant of buildings is specified as a twodimensional shape grammar with the rules S, X, Y and Z (left). Applying the rules yields a façade layout (right). Such a grammar can be facilitated for the inverse problem (Riemenschneider et al. 2012), in which a meta ruleset is given that specifies all feasible façades, and a concrete best matching parse tree from this feasible façade family is determined for a given façade photographBack to article page
