Abstract: A system and method of detecting a posture of at least one predetermined part of an object comprising the steps of extracting a first object shape from a first image taken by a first image sensor, computing a characteristic dimension value of the predetermined part within a predetermined region of the first object shape, constructing a mask based on the characteristic dimension value, extracting a profile of the predetermined part from the first object shape by applying the mask on the first object shape, and identifying at least one predefined feature point in the profile of the predetermined part, thereby detecting the posture of the predetermined part is disclosed.
