Abstract: When calculating the rotational information of the skeleton joints, the traditional data conversion method can reduce the accuracy of the rotation data. Aiming at the problem, a data conversion method for motion capture is proposed. It establishes the human body tree structure skeleton model by using the structural relationship between their own frame human skeleton model, and designs the method of construction and decomposition to solve the three freedom rotation information of the key points, and uses this information to the drive human skeleton model. Experimental results demonstrate the effectiveness of this method.

Key words: method of construction and decomposition, freedom, skeleton model, rotational information

摘要： 传统数据转换方法在计算骨骼关节点旋转信息时，会降低旋转信息的精确度。为此，提出一种新的运动捕获数据转换方法。以树型结构建立人体骨骼模型，根据关节点自身在骨架中的结构关系，通过构造分解法求解关节点的三自由度旋转信息，利用该信息驱动人体骨骼模型。实验结果验证该方法的有效性。
