Dynamic weighing method, system and equipment fused with machine vision and medium

The invention discloses a dynamic weighing method, system and equipment fused with machine vision, and a medium, and the method comprises the steps: setting a calibration vehicle, and collecting a bridge response when the calibration vehicle passes through a bridge; the method comprises the following steps: acquiring pictures of a calibrated vehicle, taking the pictures as training samples, and capturing vehicles appearing in monitoring after training is completed to obtain the length of the calibrated vehicle; setting a virtual axle on the calibrated vehicle, and obtaining a position interval of a real axle based on bridge response; and refining the position interval of the real axle, selecting an element in each position interval to construct a vehicle matrix, obtaining a plurality of groups of axle load results after iteration, and substituting the axle load results into an error formula to obtain the axle load and the axle distance of the real axle. According to the invention, a video monitoring system in
