DYNAMIC DISPLACEMENT RECOGNITION METHOD OF FRAME STRUCTURE IN COMPUTER VISION
The safety of engineering structures is increasingly receiving attention,and how to quickly evaluate the safety of structures has become a hot and difficult research topic in this field.The deformation displacement generat-ed by the structure is one of the intuitive variables in structural safety assessment.How to improve the accuracy of displacement monitoring based on computer vision is one of the focuses of research in this field.This article propos-es a structural dynamic displacement data processing method that combines non-contact and contact methods.The dynamic trajectory of the structural visual target is converted into pixel displacement,and then Kalman filtering is performed on the displacement converted from the accelerometer data to simulate the true displacement of the struc-ture.The feasibility of the proposed method is verified by identifying structural modal parameters.The research re-sults indicate that the method proposed in this paper obtains dynamic displacement of structures and has high moni-toring accuracy.
