Real time trajectory matching and outlier detection for assembly operator trajectories
2018
Flexible, reactive and adaptive manufacturing systems are a
prerequisite to cope with the demand for low volumes of
highly customized products of today’s market. For years,
manufacturing companies have been using real-time data
capturing systems, such as RFID, to gather the necessary data
to obtain insights in their production processes, mainly in the
domain of quality control and inventory management.
However, very few work has been done on monitoring an
assembly operator during his work cycle in real-time. This
paper presents a method to match operator trajectories,
obtained through a multi-camera vision system, in real-time
to predefined models. This way, the performance of the
operator can be assessed online and problematic or
anomalous work cycles can be detected. This information can
then be used to support the operator in his pursuit for
continuous improvement by pointing out improvement
potential.
