本文提出了一种基于光学跟踪系统和手部参数模型的手部运动评估方法。根据每个人的手外部尺寸缩放模型。利用光学跟踪装置对中、食指模型进行验证。采用了铰链关节转动轴线和球关节转动中心的计算方法。关节角度是通过两种方式获得的，从已知的关节旋转中心，并通过求解逆运动学的手指从给定的指尖位置。手指段的长度，通过使用统计人体测量学的数据计算，不显着不同的长度从计算的关节旋转中心。通过逆运动学获得的角度与从估计的旋转中心获得的角度相当。最小化方法使得该方法适合于传感器手套的校准
In the paper we propose a method for assessment of hand motion which is based on optical tracking system and parametric model of a hand. The model was scaled according to hand external dimensions of each individual. Optical tracking device was used for model validation which was made for middle and index finger. The algorithms for calculation of hinge joint axis of rotation and ball joint center of rotation were employed. The joint angles were obtained in two ways, from known centers of joint rotation and by solving inverse kinematics for finger from given positions of fingertips. The lengths of finger segments, calculated by using data from statistical anthropometry, do not differ notably from the lengths obtained from calculated centers of rotation of joints. The angles obtained by inverse kinematics are comparable to the angles obtained from estimated centers of rotation. Minimalistic approach makes the method suitable for calibration of a sensor glove
