The invention discloses a running vehicle steering state recognition method, which comprises the following steps: acquiring a vehicle image and vehicle parameters of a target vehicle driving into a preset monitoring area in a monitoring picture, and triggering the steering state detection of the running vehicle when the center point of a target frame in a current frame falls into a steering monitoring surface; obtaining track points of the target vehicle in a current frame and a historical frame, generating a historical track point set, carrying out segmented fitting on central points of the same vehicle at different positions in discrete time, selecting a representative point in each segment, calculating included angles formed by a vector formed by a starting point and each representative point and a horizontal line, and according to the change rule of each included angle, judging the steering state of the running vehicle. According to the method, the vehicle steering state is recognized based on the image processing method, the historical track of the vehicle is obtained after the vehicle passes through the steering monitoring face, the steering state of the running vehicle is judged in a segmented fitting mode, and the method has the advantages of being high in accuracy and processing speed, few in occupied resources and the like.

    本发明公开了一种行驶车辆转向状态识别方法,通过获取监控画面中目标车辆驶入预设的监测区域的车辆图像和车辆参数,在当前帧中的目标框中心点落入转向监测面时,则触发行驶车辆的转向状态检测,获取当前帧和历史帧中该目标车辆的轨迹点,生成历史轨迹点集合,对离散时间的不同位置同一车辆的中心点进行分段拟合,并在各段中选取一个代表点,计算起点与各个代表点组成的向量与水平线构成的夹角,通过各个夹角的变化规律,判断行驶车辆的转向状态。本发明基于图像处理的方法进行车辆转向状态识别,在车辆驶过转向监测面后,再获取该车辆的历史轨迹,通过分段拟合的方式判断行驶车辆的转向状态,具有准确率高、处理速度快、占用资源少等特点。
