    • The error of a sensor in motion capture system is corrected. An acceleration sensor determines the direction of gravity (G1) in a still initial state. The direction G1 will never change always if a drift dose not occur. However, actually if an object to which an acceleration sensor is attached moves along a coordinate axis, the direction gradually changes due to a drift with time. According to the invention, after a given time has passed, the acceleration sensor is stopped to determine the direction of gravity. Referring to the data on this determination, the true direction of gravity to be judged is compared with the direction of gravity G1 influenced by the drift. The difference between them is assumed to be an error due to a drift, and the error is subtracted from the determined value to correct the error of the measurement value. Similarly to the direction of gravity, assuming that there is an error in any direction in the coordinate system, the errors are corrected, and more accurate motion determination is possible.
    • 纠正了运动捕捉系统中传感器的误差。 一个加速度传感器决定了在初始状态下的重力方向(G 1)。 如果不发生漂移剂量,方向G 1永远不会改变。 然而,实际上如果附加有加速度传感器的物体沿坐标轴移动,则随着时间的推移,方向逐渐变化。 根据本发明,在给定时间过去之后,停止加速度传感器以确定重力方向。 参照该确定的数据,将要判断的真实重力方向与受漂移影响的重力G 1的方向进行比较。 它们之间的差异被认为是由于漂移引起的误差,并且从确定的值中减去误差以校正测量值的误差。 与重力方向类似,假设在坐标系中存在任何方向的误差,校正误差,可以进行更准确的运动确定。
