Sažetak
In this paper, detection of dominant planar surfaces in indoor scenes using stereo vision is considered. In indoor environments, many of the dominant surfaces are uniformly colored, which results in 'holes' in disparity images obtained by standard local area-based methods. Application of region based stereo reconstruction methods to cope with this problem is investigated. Region based methods rely on an image segmentation preprocessing step which segments an image into regions inside which there are no abrupt changes in disparity. Assuming that a poorly textured region obtained by image segmentation represents a single planar surface, the disparity can be assigned to all points of that region by fitting a plane to its portions which are reliably reconstructed by a local area-based stereo vision method, hence filling the gaps in the disparity image. An experimental study of this approach is reported. The experiments are performed using a stereo camera system mounted on a mobile robot.
