Description
Summary:Steel structure needs to be assembled before the components are transported to the site to ensure the installation of the steel structure successfully. The traditional assembly is a physical assembly method, which needs an amount of equipment, occupies large areas and can be labor and time-consuming. To address these issues, industrial photogrammetry has been developed to acquire data, and the steel structure has been virtually assembled in a virtual environment. The high-precision data acquisition of steel components is now carried out by using 3D laser scanner, and therefore, the feature data of those components can be automatically extracted by programming. As a result, the accurate linear shape of the post-splicing components can be extracted after completing the precise assembly of the steel structure in a virtual environment, which is significant for the subsequent mechanical analysis.
