Bridge monitoring system and method, readable storage medium and device

The invention belongs to the technical field of bridge monitoring, and discloses a bridge monitoring system and method, and a readable storage medium and device.The bridge monitoring system comprises a camera module with an optical magnification function and scale plates, the camera module is arranged on a bridge floor at a bridge pier and faces the multiple scale plates arranged on the same straight line in the length direction of a bridge, and the scale plates are arranged on the camera module. The length direction of the scale plate is perpendicular to the bridge floor; the scale plate is provided with a plurality of identification blocks right facing the light direction of the camera module, and each identification block comprises a detection mark reflecting the vertical displacement of the bridge point where the scale plate is located. The boundary marked by the positioning amplification mark comprises the rated maximum vertical displacement range of the bridge point position where the scale plate is loc
