Given a single image of an arbitrary road, that may not be well-paved, or have clearly delineated edges, or some a priori known color or texture distribution, is it possible for a computer to find this road? This paper addresses this question by decomposing the road detection process into two steps: the estimation of the vanishing point asso- ciated with the main (straight) part of the road, followed by the segmentation of the corresponding road area based on the detected vanishing point. The main technical contri- butions of the proposed approach are a novel adaptive soft voting scheme based on variable-sized voting region using confidence-weighted Gabor filters, which compute the dom- inant texture orientation at each pixel, and a new vanishing- point-constrained edge detection technique for detecting road boundaries. The proposed method has been imple- mented, and experiments with 1003 general road images demonstrate that it is both computationally efficient and ef- fective at detecting road regions in challenging conditions.

    • ... image is that the centers which are not in the ROI region can be obtained by the previous detection, as is shown in fig. 2. On the other hand, to overcome line distortion brought by fish-eye camera, the center points of raised pavement markers in accumulating image are transformed to center points in plane image which takes the vanishing point as its origin of coordinates, as is shown in fig. 7. The vanishing point can be computed by [ ...
