Investigation of dynamic working zones and movements in garment engineering

Abstract

A new measuring system for three‐dimensional video recording is described, together with its application and possibilities in investigating dynamic working zones in garment manufacturing processes, employing a kinematic method. A video recording can be processed as a series of static frames or as a dynamic series of recordings, employing a system for video recording and storing the recordings from three planes (ground plane, side view and frontal representation of a workplace). Static zones are created by movements of levels one to four, while dynamic zones are created with the help of the whole body, using movements of levels five and six. Processing is done using a contemporary computerised system, software for processing video recording and software for image processing. The new measuring system presented works together with the measuring system for the processing parameters of garment sewing operations, and enables the investigator to work on movement cyclograms and dynamic workingzones, depending on the processing parameters,operation structure and workplace designing.Results obtained relevant for the investigations in garment engineering processes are described, with the emphasis on work study and workplace designing in the garment industry – the need to measure spatial values (angles, distances, dimensions etc.), temporal values (duration of the movements, movement trajectories, acceleration etc.). The process ofcreating a cyclogram for the graphic presentation of movements is also presented.
