The invention provides a method and a device for identifying the state of a vehicle in an emergency parking strip. The method comprises the following steps of: acquiring monitoring video stream data including the emergency parking strip by using video monitoring equipment; constructing a projection plane, and projecting the monitoring image sequence to the projection plane in a homogeneous transformation mode to obtain a projection image sequence; and calculating the actual distance of the unit coordinates in the projection plane based on the actual length of the dotted line in the emergency parking strip, obtaining the real state vector of each target vehicle in the projection image sequence based on the actual distance of the unit coordinates, and judging the vehicle state of the corresponding target vehicle based on the real state vector of each target vehicle. According to the scheme, the monitoring video stream data is acquired and decoded, the image is subjected to preprocessing, target recognition, projection transformation and coordinate calculation, and the real state vector of the vehicle is acquired by using Kalman filtering, so that the states of the vehicle, such as driving in, stopping, driving out and retrograde running, in the emergency parking strip are judged, and accurate recognition is carried out.

    本申请提出了一种紧急停车带内的车辆状态识别方法及装置,包括以下步骤:使用视频监控设备获取包括紧急停车带的监控视频流数据;构建投影平面,以齐次变换的方式将监控图像序列投影至所述投影平面中得到投影图像序列;基于紧急停车带内的虚线实际长度计算投影平面中单位坐标的实际距离,基于单位坐标的实际距离获取投影图像序列中每一目标车辆的真实状态向量,基于每一目标车辆的真实状态向量判断对应目标车辆的车辆状态。本方案通过获取监控视频流数据并解码,对图像进行预处理、目标识别、投影变换和坐标计算,利用卡尔曼滤波获取车辆真实状态向量,进而判断紧急停车带内车辆的驶入、停止、驶出、逆行等状态进行精准识别。
