OpenVR has an error in obtaining data for VR headsets and controllers

[Recialhot]

when i run this，the z-coordinate of the positioning data is in the second position, and there is clearly an issue. Why is this？

code:

def convert_to_numpy(matrix): return np.array([[matrix.m[0][0], matrix.m[0][1], matrix.m[0][2], matrix.m[0][3]], [matrix.m[1][0], matrix.m[1][1], matrix.m[1][2], matrix.m[1][3]], [matrix.m[2][0], matrix.m[2][1], matrix.m[2][2], matrix.m[2][3]], [0.0, 0.0, 0.0, 1.0]])

hmd_pose = get_device_pose(poses, openvr.k_unTrackedDeviceIndex_Hmd) if hmd_pose:

    hmd_matrix_np = convert_to_numpy(hmd_pose)

    position = hmd_matrix_np[:3, 3]
    rotation = hmd_matrix_np[:3, :3]
    print("Headset Pose:")
    print("Position: ", position)
    print("Rotation: ", rotation)

result: Position: [-0.1273, 1.5742, 0.4805]
