Bridge dynamic weighing method based on vision technology assistance and related equipment

The invention discloses a bridge dynamic weighing method based on vision technology assistance and related equipment, and the method comprises the steps: determining initial strain data according to the obtained maximum strain data generated by a target vehicle to a target detection point in an entrance region on a target bridge section; strain data generated by each influencing vehicle on the target bridge section on the target detection point is calculated as influencing strain data, and the influencing vehicles are vehicles except the target vehicle on the target bridge section; fusing the initial strain data and the influence strain data to obtain target strain data; and calculating the weight according to the target strain data to obtain the target weight corresponding to the target vehicle. A groove does not need to be formed in the bridge floor to embed an induction coil or a traffic radar, traffic does not need to be interrupted during installation or maintenance, and timely maintenance is facilitated
