Rapid Lane Recognition Based on the Road Region

As people´s awareness of safety is enhancing, the intelligent vehicle navigation system is paid more attention. The lane recognition is the main approach used by the navigation technology. The algorithm of extracting the lane region is improved in this paper against the past algorithms with poor real-time. Firstly, this algorithm extracts the road region based on the clear dividing line between the road region and non-road region. And next, the road region is scanned vertically from bottom to up by the scanning algorithm using dichotomy, while the lane regions are also extracted. This algorithm improves the efficiency compared with other scanning algorithms. Lastly, according to the lanes´ features the lanes can be further recognized. The experiment results show that this algorithm clearly improves the system´s operation efficiency and accuracy.
