Design of a bridge digital twin system for Intelligent operation and maintenance based on machine vision

Under the background of the transformation and upgrading of bridge maintenance management, aiming at the problems of weak processing capacity, low management efficiency and intelligent degree of the bridge operation and maintenance process, this paper proposes a digital twin system solution of bridge intelligent operation and maintenance based on machine vision. Then framework of the bridge digital twin system for Intelligent operation and maintenance is proposed, followed by the realization methods based on machine vision. Finally, a case application of the concrete simply supported girder bridge is given.
