The invention discloses a traffic abnormal event detection system and method, and the system comprises a monitoring data obtaining module which is used for monitoring a road, and obtaining continuous monitoring data in a certain monitoring duration range; the target feature extraction module is used for extracting driving features of the vehicle based on the monitoring data; the prediction module is used for inputting the driving characteristics into a vehicle detection model for suspicious vehicle detection to obtain position information of the suspicious vehicle; the suspicious vehicle tracking module is used for acquiring a driving track and a driving speed of the suspicious vehicle by adopting a feature point matching tracking method according to the position information of the suspicious vehicle, judging whether the suspicious vehicle is an abnormal vehicle or not, and acquiring a judgment result; and the abnormal event detection module is used for detecting the category of the abnormal event according to the judgment result. According to the invention, the accuracy of traffic abnormal event detection is further improved.

    本发明公开了一种交通异常事件检测系统及方法,系统包括监控数据获取模块:用于对道路进行监控,获取在一定监测时长范围内连续的监控数据;目标特征提取模块:用于基于所述监控数据提取车辆的行驶特征;预测模块:用于将所述行驶特征输入至车辆检测模型中进行可疑车辆检测,获得所述可疑车辆的位置信息;可疑车辆追踪模块:用于根据所述可疑车辆的位置信息,采用特征点匹配跟踪方法,获取可疑车辆的行驶轨迹及行驶速度,并判断所述可疑车辆是否为异常车辆,获取判断结果;异常事件检测模块:用于根据所述判断结果对异常事件类别进行检测。本发明进一步提高了交通异常事件检测的准确性。
