SolvePnP returns rotation and translation to transform object from initial 3d coordinates to camera coordinate system. In this system camera is located in (0,0,0). And it oriented along Z axis. So if you know object position in your global system you can find new camera coordinates in this system too. Also you can imagine that inverted found transformation describes motion of camera. So if you know camera position in initial time moment you can apply inverted transformation to got new camera position.
