This paper describes a multiple view based approach for building modeling via a novel multi-box grammar, which represents an occlusion relationship among the projections of a set of buildings sharing a common Manhattan World coordinate system. We formulate the building modeling problem as an energy minimization to combine the constraints from the multi-box grammar with (1) the semantic labeling information from appearance models, (2) the directional information w.r.t the vanishing points in each single view, and (3) the planar homography correspondence among multiple views. We further propose a two-step coarse-to-fine approach to achieve the optimal solution. First we employ super-pixels and a simplified edition of the grammar to reduce the searching space, and obtain an initial layout to accelerate the convergence speed. At the second stage, the scene model is refined to achieve pixel-level accuracy by minimizing the energy using Random Walk. Experiments on street view images demonstrate the capability of our method in reconstructing multiple buildings at different distances, and also the robustness in handling occlusion. |
