Bridge monitoring method and system based on binocular vision

The invention relates to a bridge monitoring method and system based on binocular vision, and the method comprises: calibrating a first camera and a second camera, obtaining the relative pose relationbetween the two cameras, and determining the real-time three-dimensional coordinates of a central point on a calibration plate under a first camera coordinate system; calculating a coordinate conversion relationship between the first camera coordinate system and the calibration plate coordinate system according to the calibration information, and converting a three-dimensional coordinate of the central point under the first camera coordinate system into a real-time three-dimensional coordinate under the calibration plate coordinate system; and determining the displacement information of the bridge by combining the three-dimensional coordinates of the central point at the initial moment under the calibration plate coordinate system. By calibrating the relative pose relationship between thetwo cameras, the three-di
