Real-time data analysis and 3D representation for postural assessment in manufacturing processes

Industry 4.0 passes through the concept of smart factory, bringing into the industrial context a new vision of production lines and workflows, which can now be designed considering ergonomics and thus the interaction among operators, machines and tools. Virtual simulations help in reproducing such interactions and in foreseeing solutions to improve the working conditions before installing tools and equipment. Motion capture techniques have proven capable to guarantee the reproduction of human motion with sufficient accuracy. The present work aims at the development of an integrated tool for ergonomics risk assessment index calculation, using motion capture in 3D environments: an engine for postural angle calculation, in accordance with international standards, together with a Unity-based application have been specifically designed and validated. The work is part of the IM.PR.ES.S.E.D. (IMmersive PRocESs ergonomicS by wEarable Devices) project.
