The embodiment of the invention discloses a rear-end collision prevention vehicle-mounted intelligent system based on the visual recognition technology and a monitoring method. The rear-end collisionprevention vehicle-mounted intelligent system comprises a display lamp area, a vision detection system and a data processing system, wherein the data processing system is used for receiving data collected by the vision detection system, regulating and controlling the driving behavior of a vehicle according to the driving states of front vehicles and actively reminding rear vehicles of the currentreal-time driving state; the display lamp area comprises but is not limited to two steering reminding lamps and a driving speed reduction reminding lamp; the data processing system uses an image quadrant segmentation method to determine whether the steering reminding lamp is turned into a lane where the vehicle is located or not so as to accurately pre-judge the rear-end collision prevention braking time point, and the data processing system pre-judges the rear-end collision prevention braking time point by identifying the flicker frequency of the driving speed reduction reminding lamp; and the data processing system actively reminds the driver of the vehicle to change the driving state at the braking time point; The implementation mode in detecting the turning situation of the front vehicles is simple, and the timeliness and safety of calculating the braking time point are improved.

    本发明实施例公开了一种基于视觉识别技术的防追尾车载智能系统及监控方法,包括显示灯区;视觉检测系统和数据处理系统,数据处理系统用于接收视觉检测系统的采集数据,根据前车的驾驶状态调控车辆的驾驶行为,且主动提醒后车当前的车辆的实时驾驶状态,显示灯区包括但不限于两个转向提醒灯和驾驶降速提醒灯,数据处理系统利用图像象限分割法确定转向提醒灯是否转入车辆所处的车道,以准确预判防追尾的刹车时间点,且数据处理系统通过识别驾驶降速提醒灯的闪烁频率预判防追尾的刹车时间点,且在数据处理系统在刹车时间点主动提醒车辆的驾驶员更改驾驶状态;本发明检测侧前车的转弯情况的实现方式简单,以提高计算刹车时间点的及时性和安全性。
