Abstract: Collecting body measurements correctly in motion state and understanding its changes are very important on apparel ease design. Traditional manual method with tape and 3D body scanning are developed based on human body in static state, so these methods are limitation on body anthropometry in motion state. In order to acquire body measurements in motion state, one method with body motion analysis system is explored and presented in this paper. For the effectiveness of this proposed method, a series of experiments are designed and carried out to collect measurement data in static state, dynamic postures and motion state. Based on the collected data and analysis results, this exploring method is proved that the body measurements in motion state acquired by the body motion analysis system are accurate and this method is effective, which can help designer to determine correct apparel ease allowances and make pattern. Finally, the limitations in this method are analysed and corresponding improve methods are introduced.

Key words: body anthropometry, bodymotion analysis, body measurement in motion state, ease design, pattern making
