Evaluation of Photogrammetry for Use in Industrial Production Systems

Paper i proceeding, 2018

A digital twin of a production system consists of geometric, kinematic and logical models of the physical system. One of the key challenges is to keep the digital twin up-to-date with changes of the real one. Today, laser scanning is the de-facto standard used to keep the geometry of the digital model synchronized. In recent years, advancements in the performance of Graphic Processing Units (GPUs) and the availability of cheap high-resolution digital cameras have made photogrammetry a viable alternative to laser scanning for building digital 3D-models. In this study, we investigate how photogrammetry competes against laser-scanning by comparing their results in form of point-clouds.
