Abstract：To solve the acquisition difficulty of toddler's walking gait, a Kinect-based natural gait extraction approach is proposed. The human body's skeletal information is acquired directly by Kinect to collect the joints data of toddlers of different months. The joint position smoothing and bone length curve fitting are utilized to realize filtering and acquisition of bone data. The temporal-spatial gait parameters of toddlers of different months are extracted by fitting the foot trajectory of the walking toddler. By means of the inverse kinematics of the lower limb, the changes of joint angles are obtained and the gait variation characteristics of the walking toddler are deduced.
