In order to reduce the false alarm rate of the lane departure warning system based on machine vision, a new lane departure warning system considering the driver's intention of changing lanes is put forward. In the proposed system, the collected road image information is filtered with Steerable Filter method, the road parameters are extracted using the local search algorithm, and the speed of motor vehicle, turning signal, lane departure situation as well as the driver's head movement are detected to judge the driver's lane departure intention. A lane departure warning decision algorithm is develped. Verification of the algorithm and simulation experiment are done using Matlab, with videos collected from vehicles. The results show that the proposed lane departure warning system is feasible. The system is more reliable, which can distinguish an intentional lane departure from unintentional lane departure and effectively avoid false alarm when the driver intends to change lanes.
