I assume you don't really mean that you're applying a different rotation matrix Ri and translation vector Ti to each point. That wouldn't make sense. A translation is sufficient to make 2 points coincide and is given simply by Ti=Ui-Vi. Adding rotation component would just create infinite non-unique solutions.
