This thesis presents a work addressing the theme of measurement assisted assembly using optical 3D metrology. Today, in aeronautic and transport manufacturing sectors, component assembly is carried out largely using dedicated jigs. With the advent of new digital technologies, these industries are undergoing significant adaptation and modernization. The increasing accessibility of non-contact measurement systems and the Industry 4.0 revolution both influence conventional assembly processes. It is now possible to use 3D metrology systems to assist, in real time, positioning and orientation operations during assembly; we call this measurement assisted assembly.
The objective of this project is to estimate the metrological performance of a photogrammetry 3D measurement system used in such an assembly process. Like any new technology, the lack of knowledge and the novelty of the approach present their share of problems. This work adapts and redefines existing theories of measurement uncertainty assessment into a methodology to identify the metrological performance of an assembly cell by 3D measurement. The final proposal presents a rigorous experimental methodology to estimate the repeatability and reproducibility of the system. Finally, it presents an approach to identify and model the behavior of error in the workspace.
