This paper describes a method to estimate a set of body dimensions of a subject using the Microsoft Kinect sensor. Principal Component Analysis(PCA) of the AIST anthropometric database shows principal components are interpreted as scale, degree of obesity, length of the upper body, size of the thigh and size of the buttocks respectively. A few body dimensions were chosen by linear multiple regression analysis. Applying the resulting estimator to a given subject using the Kinect sensor to obtain joint positions and 5 body dimensions by analyzing depth image, we can estimate a set of body dimensions for the subject. The system is described and experimental results are shown.
