Kinect V2 - 存储点位置时的重复值

Question

这是我用来记录包含一些计算的点的代码。所以，我得到了点的值位置，做了一些数学运算，然后将它们保存到列表中。

gesture.L.E.AddFrameDescriptor(
    joints[JointType.ElbowLeft].Position.X, joints[JointType.ElbowLeft].Position.Y, joints[JointType.ElbowLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.L.W.AddFrameDescriptor(
    joints[JointType.WristLeft].Position.X, joints[JointType.WristLeft].Position.Y, joints[JointType.WristLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.L.H.AddFrameDescriptor(
    joints[JointType.HandTipLeft].Position.X, joints[JointType.HandTipLeft].Position.Y, joints[JointType.HandTipLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );


gesture.R.E.AddFrameDescriptor(
    joints[JointType.ElbowRight].Position.X, joints[JointType.ElbowRight].Position.Y, joints[JointType.ElbowRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.R.W.AddFrameDescriptor(
    joints[JointType.WristRight].Position.X, joints[JointType.WristRight].Position.Y, joints[JointType.WristRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.R.H.AddFrameDescriptor(
    joints[JointType.HandTipRight].Position.X, joints[JointType.HandTipRight].Position.Y, joints[JointType.HandTipRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );

出于某种原因，我得到了很多重复的值，重复了20次。我注意到如果我只保存了一个值，我得到了显着的值，没有更多的重复，加上值的差异更接近于0.05513然后0.05413相比那些重复一次我得到二十分0.05513然后接下来是二十分之0.05013。

EDIT 以下是我将多个值存储到列表中时获得的示例值。

正如你所看到的，这些数字重复了二十次。
