Human-model based movement-capturing without markers for ergonomic studies

This paper presents a movement measurement system to acquire human motion data without markers. The system uses an accurate human man model as template to measure, based on image processing, movements. This method enables quick ergonomic measurements because no preparation of a subject with markers or special clothes is needed. All results which are achieved with this system are conform to the used man model and can be directly used for human modeling. Exemplary three investigations are presented concerning in-vehicle head and arm movements and riding a bike.
