The invention discloses a lane departure early warning method and system, and the method comprises the steps: collecting image information in a driving process through a front camera, detecting a lane line, judging the position of a vehicle on a current driving road, judging whether the vehicle deviates or not through a constructed vehicle departure early warning model, and if yes, judging whether the vehicle deviates or not through the vehicle departure early warning model. In order to reduce the false alarm condition, the head motion state and pupil sight gazing direction information of the driver are collected through an internal camera when the vehicle runs, the intention of the driver to autonomously change the lane is deduced, and then the early warning information analyzed by the deviation early warning model is combined to finally give the early warning result of the current vehicle deviation. Therefore, the early warning accuracy and flexibility can be improved.

    本发明公开了一种车道偏离预警方法及系统,包括:在车辆行驶过程中,通过前置摄像头采集行驶过程中的图像信息,对车道线进行检测,判断出车辆在当前行驶道路上的位置,然后通过构建的车辆偏离预警模型,判断出车辆是否发生偏离,为了减少误报的情况,通过内部摄像头采集车辆行驶时驾驶员的头部运动状态和瞳孔视线注视方向信息,推断出驾驶员自主变道的意图,然后结合偏离预警模型分析出的预警信息,最终给出当前车辆偏离的预警结果。可见,本发明能够提高预警准确性和灵活性。
