Diffused Region of Hough Method Based Road Detection Algorithm

Road identification and detection is the essential problem to be solved in intelligent vehicle systems. As the complexity dimension of the surrounding environment increases, road recognition becomes much harder under different interferences. To increment the robustness and interference immunity, a diffused region of Hough based road detection algorithm is proposed in this paper. This algorithm incorporates the global information of road shape, the assistance usage of the diffused region pixels around the road edges in the feature space. Meanwhile, the computing complexity can be decreased and the real-time ability can be increased with the aid of some pre-knowledge and estimated orientation parameters through additional sensor modules. Experiments with images sampled in our system proved the effectiveness and applicability of this method.
