Because of the advantages of easy deployment, low cost and non-contact,computer vision-based structural displacement acquisition technique hasreceived wide attention and research in recent years. However, the displacementfield acquisition of large-scale structures is a challenging topic due to thecontradiction of camera field of view and resolution. This paper presents alarge-scale structural displacement field calculation framework with integratedcomputer vision and physical constraints using only one camera. Firstly, thefull-field image of the large-scale structure is obtained by processing themulti-view image using image stitching technique; secondly, the full-fieldimage is meshed and the node displacements are calculated using an improvedtemplate matching method; and finally, the non-node displacements are describedusing shape functions considering physical constraints. The developed frameworkwas validated using a scaled bridge model and evaluated by the proposedevaluation index for displacement field calculation accuracy. This paper canprovide an effective way to obtain displacement fields of large-scalestructures efficiently and cost-effectively.
