In modular construction, the geometric and dimensional quality control of factory-assembled modules is crucial. Controlling key characteristics (e.g., overall dimensions, squareness error, and the parallelism of ceilings and floors) is essential to ensure a module’s conformity with the technical specifications and estimate the adjustment shims needed when stacking modules on-site.
Traditionally, this process is carried out using manual measurements and specialized tools. If necessary, adjustments and corrections are made a posteriori, which leads to a loss of productivity.
The advent of medium- and large-scale 3D metrology offers a promising alternative, since it makes it possible to take precise measurements in situ. Augmented reality also enables the immersive projection of information and guidance instructions. When combined, these two technologies offer the potential to improve manufacturing performance.
The aim of this project is to present a proof of concept of a solution that combines industrial photogrammetry and augmented reality to integrate dimensional and geometric quality control into the module assembly process in the factory.
The proposed system offers an immersive experience by projecting measurement data in real time when assembly parts are being positioned and adjusted, and also supports the documenting of inspection results. Laboratory and factory tests were conducted to assess the system’s user-friendliness and identify areas for improvement for future implementation.
