Embodiment 1
[0051] Such as figure 1 As shown, this embodiment provides a method for monitoring space-time loads of bridge vehicles, including the following steps:
[0052] Install a dynamic weighing system and a vision system on the bridge, and synchronize the time stamps of the two. The dynamic weighing system is used to detect vehicle loads, and the vision system is used to detect vehicles in the bridge;
[0053] Construct a panoramic view of bridge deck vehicles based on the vision system;
[0054] Use the pre-built and trained vehicle detection model to recognize the position of the vehicle in the nth frame of the bridge deck vehicle panorama acquired by the vision system in real time, and obtain the detection frame of the vehicle;
[0055] Through the preset improved Kalman filter model, according to the image frame before the nth frame of the bridge deck vehicle panorama in real time, predict the prediction frame of the corresponding vehicle in the nth frame of the bridge deck vehicl...
Embodiment approach
[0082] As a preferred implementation, the acquisition of vehicle space-time loads includes:
[0083] Taking the time passing through the dynamic weighing system and the lane passing through the dynamic weighing system as an index, the vehicle information acquired by the weighing system is reordered;
[0084] Taking the time passing through the dynamic weighing system and the lane passing through the dynamic weighing system as indexes, the vehicle information acquired by the vision system is reordered; the time passing through the dynamic weighing system and the lane passing through the dynamic weighing system are indexed by the dynamic weighing system Heavy system acquisition;
[0085] Compare and match the vehicle information obtained by the two systems one by one. Vehicles that only appear in one of the dynamic weighing system and the vision system are regarded as wrongly detected vehicles, and are deleted, and the information of the matching vehicle is retained, including l...
