The invention provides a static vehicle detection method and a static vehicle detection system based on a frame difference method, which can solve the technical problems that a traditional algorithm cannot meet the requirement for real-time processing of road condition information and meanwhile static vehicle information cannot be detected. The static vehicle detection method comprises the steps of: acquiring road condition video data; identifying moving vehicles by adopting a traditional frame difference method; carrying out ID setting on the vehicles entering a defined video image region insequence; recording and storing the position coordinates of the vehicles in an image by taking one frame as a time interval; processing the vehicle parking condition; and finally, analyzing vehicle behaviors by calculating the complete track coordinates of the vehicles to obtain speeds, driving time, driving directions and possibility of staying or not of the ID vehicles and the number of vehiclesunder the current road section. According to the static vehicle detection method, the information of the static vehicles can be matched with the information of the restarted vehicles, even if the vehicles are jammed or at a traffic light intersection, accurate road condition information can still be obtained through adopting the algorithm, and the application range of the traditional frame difference method is enlarged.

    本发明的一种基于帧差法的静止车辆检测方法及系统,可解决传统算法不能满足路况信息实时处理的要求,同时不能够检测静止车辆信息的技术问题。包括获取路况视频数据;采用传统帧差法,标识出运动车辆;依次对进入所划定的视频图像区域的车辆进行ID设置;车辆位置记录以一帧为时间间隔,记录并保存车辆在图像中的位置坐标;对车辆停留情况处理;最后通过对车辆完整轨迹坐标的计算分析车辆行为,得出该ID车辆的速度,行驶时间,行驶朝向是否停留和当前路段下车辆的个数。利用本发明可以将静止后的车辆信息与重新启动后车辆的信息进行匹配,即使是在车辆拥堵或者是红绿灯路口,利用本算法依然可以得到准确的路况信息,增加了传统帧差法的适用范围。
