Measurement of the posture of the playing children

Recently, children are less active than they used to be. Decreasing of children\´s physical strength is becoming a problem. There are many data about physical strength, but there are few numerical and statistical data about exercise ability. Therefore, the no-contact sensing system which can measure children\´s exercise ability numerically and statically should be developed. This research is measures children\´s posture by using "Relative Stereo 3D measurement method" as a first step to analyze the exercise ability.
