The invention is suitable for the technical field of intelligent traffic, and provides a traffic flow rapid statistical method based on a geomagnetic sensor and target detection, comprising the following steps: when the geomagnetic sensor is triggered by a vehicle, automatically triggering a camera to photograph a designated area, and collecting a photographed picture; classifying and filtering the collected pictures by adopting a target dichotomy algorithm to obtain two types with the vehicle target quantity equal to one and greater than one in the pictures; and for the picture of which the target number is greater than one, counting the targets in the picture through a target detection algorithm, and calculating traffic flow data in combination with the camera triggering times. The geomagnetic sensor is used for sensing passing vehicles, the camera is automatically triggered to take pictures, pictures of single targets are filtered in a picture dichotomy mode, target detection of deep learning is carried out on the pictures with the targets larger than one, the number of the vehicles in the pictures is obtained, then the result is corrected, and finally the traffic flow data obtained through statistics are accurate. And the statistical mode processing efficiency is high.
本发明适用于智慧交通技术领域,提供一种基于地磁传感器和目标检测的车流量快速统计方法,包括:当地磁传感器受到车辆触发时,自动触发摄像头对指定区域进行拍照,收集拍照图片;采用目标二分类算法对收集的图片进行分类过滤,得到图片中车辆目标数量等于一和大于一的两类;对于目标数量大于一的图片,通过目标检测算法对图片中的目标进行计数,并结合摄像头触发次数,计算得到车流量数据。本发明用地磁传感器感应经过车辆,自动触发摄像头拍照,通过图片二分类方式过滤单目标的图片,对于目标大于一的图片进行深度学习的目标检测,得到图片中车辆数量,然后对结果进行修正,最终统计得到的车流量数据准确,统计方式处理效率高。
