The invention discloses an unmanned aerial vehicle-fused drunk driving vehicle driving abnormal state discrimination method, which utilizes data processing and unmanned aerial vehicle technologies to monitor vehicle driving track abnormity and identifies drunk driving behaviors through scoring. Firstly, a data processing module establishes a vehicle swing judgment model, a vehicle sudden speed change judgment model and a signal lamp intersection waiting duration judgment model through multi-feature evaluation indexes, and scores are assigned to the track abnormal degree; when the total score exceeds a threshold value, judging whether a novice driving sign exists or not; then, the data generation module dispatches an unmanned aerial vehicle to recognize the face state of the driver and judges whether the driver has feature factors of drunk driving or not; and finally, a terminal information judgment module determines whether the overall comprehensive index exceeds a specified threshold value or not so as to judge whether a drunk driving condition exists or not. According to the invention, the problems of missing detection, lagging detection and interference on normal drivers in the existing drunk driving judgment method are solved, and the accuracy, real-time efficiency and coverage of drunk driving judgment are improved.

    本发明公开了一种融合无人机的酒驾车辆行驶异常状态判别方法,利用数据处理和无人机技术来监测车辆行驶轨迹异常,通过评分来识别酒驾行为。首先,数据处理模块通过多特征评价指标建立了车辆摇摆判别模型、车辆突然变速判别模型以及信号灯交叉口等待时长判别模型,并对轨迹异常程度进行赋分;当总分超过阈值时,判断是否存在新手驾驶标志;然后,数据生成模块派出无人机对司机的脸部状态进行识别,判断司机是否具有酒驾的特征因素;最后,终端信息判断模块确认总体综合指数是否超过规定阈值,以判定是否存在酒驾情况。本发明解决了现有酒驾判别方法存在漏检、检查滞后及干扰正常驾驶人的问题,提升了判别酒驾的准确性、实时效率及覆盖面。
