Euler angles in ground truth

[hueledao]

Hello Manon Kok,

I had a problem when running your source code. The Euler angles (converted from quaternion ground truth) are different from the simulation data that you wrote in the paper. (For example, as I understand, the roll and yaw should be zero angles when rotating pitch angle, but I received +180 degrees in there, please see the figure in the following link).

I would be happy if you can explain it to me, thank you very much ^^
