The invention belongs to the technical field of highway bridge safety monitoring image data identification, and discloses a wide bridge vehicle load identification method, identification system and equipment and a storage medium. The method comprises the following steps: acquiring real-time video frame images of traffic flow of each lane of a wide bridge floor by using a cross bridge multi-camera and bridge dynamic weighing system, and performing real-time image fusion based on a multi-camera position relationship; acquiring a bridge strain response when the traffic flow passes through the bridge through a strain sensor arranged at the bottom of each main beam of the bridge; recognizing the real-time spatial position, the axle number and the axle distance of the vehicle on the wide bridge floor according to a real-time video image obtained by fusing the real-time images of the traffic flow crossing the bridge; according to the real-time spatial position of the vehicle, inquiring and acquiring influence surface data of a corresponding position; and according to the acquired bridge strain response influence surface data, calculating the axle load and the total weight of multiple vehicles. The present invention reduces axle load identification errors caused by incorrect vehicle position or influence line calibration.
本发明属于公路桥梁安全监测图像数据识别技术领域,公开了一种宽桥车辆荷载识别方法、识别系统、设备及存储介质。所述方法包括:利用横桥多摄像及桥梁动称重系统采集宽桥面各车道交通车流的实时视频帧图像,并基于多摄像头位置关系进行实时图像融合;通过设置于桥梁每根主梁梁底的应变传感器采集交通车流过桥时的桥梁应变响应;根据交通车流过桥的实时图像融合后的实时视频图像识别车辆在宽桥面上的实时空间位置、轴数和轴距;并根据车辆的实时空间位置查询获取相应位置的影响面数据;根据采集到的桥梁应变响应影响面数据计算出多车的轴重和总重。本发明减少由于不正确的车辆位置或影响线校准而引起的轴重识别错误。
