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.
