The invention discloses an expressway traffic event detection method based on image processing. A real-time monitoring video of an expressway is obtained; frame processing is carried out on the real-time monitoring video; extracting a plurality of continuous pictures in the real-time monitoring video; a pre-trained target detector is used to identify vehicles in each picture. Performing multi-target tracking on the vehicle in each picture; the movement state of each vehicle is analyzed in the multi-target tracking process; therefore, the current state of the expressway is judged to be the normal driving state, the overspeed driving state or the continuous low-speed state, real-time detection of traffic events such as the normal driving state, the overspeed driving state or the continuous low-speed state of vehicles on the expressway is achieved, and the detection precision of the traffic events on the expressway can be improved.
本发明公开了一种基于图像处理的高速公路交通事件检测方法,通过获取高速公路的实时监控视频,并对实时监控视频进行帧处理,提取出实时监控视频中连续的多个图片,采用预先训练的目标检测器识别各个图片中的车辆,对各个图片中的车辆进行多目标追踪,在多目标追踪过程中对各个车辆的运动状态进行分析,以判断高速公路当前状态为正常行驶状态、超速行驶状态或者持续低速状态,实现对高速公路上车辆正常行驶状态、车辆超速行驶状态或者车辆持续低速状态等交通事件的实时检测,可以提高高速公路上上述交通事件的检测精度。
