Research on Deformation Monitoring Technology of Structure Based on Machine Vision

At present, video surveillance has covered the whole process of construction, operation and maintenance of important traffic infrastructure such as ship locks, Bridges and waterways. In order to further tap the potential value of video surveillance data and meet the needs of automatic identification and control of the safety status of traffic infrastructure structures, image recognition technology and information technology are used to study the structural displacement measurement algorithm based on image recognition. The structure displacement measurement algorithm based on machine vision and the structure displacement measurement system based on machine vision were developed to measure the two-dimensional deformation of the object surface by analyzing the two images before and after deformation, and directly measure the displacement and deformation field of the surface of various scales under the action of loads. It has been proved by experiments that the measurement accuracy of the structure displacement based on machine vision has reached millimeter level. Meet the requirements of the existing relevant codes, and provide security for the construction site.
