The invention relates to a traffic flow detection method and apparatus, computer equipment and a storage medium. The method comprises the steps of obtaining a detection baseline and a detection threshold; initializing a traffic flow value corresponding to a detection area covered by the geomagnetic sensor; acquiring detection data from the geomagnetic sensor to obtain initial data; preprocessing the initial data to obtain target data; judging whether a vehicle passes through a detection area covered by a geomagnetic sensor or not according to the target data; if a vehicle passes through a detection area covered by the geomagnetic sensor, updating a corresponding vehicle flow value; counting the traffic flow value to form a counting result; and feeding back the statistical result to the terminal for traffic scheduling reference. The geomagnetic sensor is high in reliability, small in limitation and low in cost, and the problems that in a traditional vehicle detection scheme, the cost ishigh, and the requirements for reliability and safety in scenes with complex and changeable traffic conditions are difficult to meet are solved.

    本发明涉及车流量检测方法、装置、计算机设备及存储介质,该方法包括获取检测基线和检测阈值;初始化地磁传感器所覆盖的检测区域对应的车流量数值;获取来自地磁传感器的检测数据,以得到初始数据;对所述初始数据进行预处理,以得到目标数据;根据所述目标数据判断地磁传感器所覆盖的检测区域内是否有车辆经过;若地磁传感器所覆盖的检测区域内有车辆经过,则更新对应的车流量数值;对所述车流量数值进行统计,以形成统计结果;反馈所述统计结果至终端,以供流量调度参考。本发明采用地磁传感器可靠性高、局限性小,成本低,实现解决传统的车辆检测方案中成本较高且难以满足在交通状况复杂多变的场景中的可靠性和安全性要求的问题。
