We consider the problem of estimating 3D structure from a single still
image of an outdoor urban scene. Our goal is to efficiently create 3D
models which are visually pleasing. We assume that the environment is
made of a number of vertical walls and a round plane like in Hoiem et al,
but introduce additional constraints on resulting 3D model structure. We
achieve computational efficiency by special preprocessing together with
stagewise search of 3D model parameters, dividing the problem into two
smaller sub-problems on graphs with simple structure.
The use of Conditional Random Field models for both problems allows to
capture appearance, geometric and context cues. Orientation of vertical
walls of 3D model is recovered from vanishing points. Compared to
Hoiem et al
[1], proposed framework has lower run-time complexity, while producing
3D models of urban scenes of comparable or better visual quality.
