Innovative bridge monitoring using computer vision and AI: 10 years of experience in Denmark and the UK

The author of the article has led and managed 40 bridge monitoring projects over the past 10 years in the UK and Denmark, focusing on critical bridge infrastructure. This article describes selected projects and the practical application of image analysis and computer vision in the monitoring of various types of bridges, including railway, road, suspension, and drawbridges. It also presents the use of image analysis for monitoring stresses, displacements, and rotations of key bridge elements such as bearings, expansion joints, cables, and girders. Thanks to the use of computer vision monitoring based on cameras and smartphones, bridge managers have extended the service life of their assets and achieved savings amounting to millions of pounds (tens of millions of Danish kroner)
