lingran confirmed that the question is solved:
Thanks Bruno!

The problem of the consistence is because a 'minus sign' was forgotten in my python code.
The results are quite close after the mistake has been fixed. See:

#relativeVelocity = (rbp2->vel-rbp1->vel)*alpha +
rbp2->angVel.cross(-radius2*normal) -
rbp1->angVel.cross(radius1*normal);

relVel=(vel2-vel1)*alpha+np.cross(rb*n,angVel2)-np.cross(ra*n,angVel1)
##getIncidentVel


Best regards.
lingran
