The invention discloses a method, a device and equipment for determining the driving speed of a vehicle passing through a traffic intersection, and relates to the field of image processing and intelligent transportation. According to the specific implementation scheme, the method comprises steps of in response to an image, collected by a first camera applied to a traffic intersection, of a vehicle driving into the traffic intersection, determining a first moment; in response to an image, collected by a second camera applied to the traffic intersection, of the corresponding vehicle driving out of the traffic intersection, determining a second moment; according to the first moment and the second moment, querying to obtain a target driving track; wherein the positioning of the target driving track at the first moment is in the visible range of the first camera, and the positioning of the target driving track at the second moment is in the visible range of the second camera; determining a driving distance between the first moment and the second moment according to the target driving track; and determining the driving speed according to the driving distance and the time difference between the first moment and the second moment. According to the scheme, the accuracy of the driving speed calculation result can be improved.

    本申请公开了一种通过交通路口车辆的行驶速度确定方法、装置和设备,涉及图像处理和智能交通领域。具体实现方案为:响应于应用于交通路口的第一摄像头采集到车辆驶入交通路口的图像,确定第一时刻;响应于应用于交通路口的第二摄像头采集到相应车辆驶出交通路口的图像,确定第二时刻;根据第一时刻和第二时刻,查询得到目标行驶轨迹;其中,目标行驶轨迹中第一时刻的定位处于第一摄像头可视范围,且第二时刻的定位处于第二摄像头可视范围;根据目标行驶轨迹,确定第一时刻和第二时刻之间的行驶距离;根据行驶距离,以及第一时刻与第二时刻之间的时间差,确定行驶速度。该方案能够实现提升行驶速度计算结果的准确性。
