It is hard to say, I think you have to save the whole map (keyframes, points and relations between them). Then, you can use the DBoW2 to relocalise the current camera with respect to the leyframes stored. You should use the feature extracted in the keyframe to do the relocalisation. Once you relocalise the current camera, you can start tracking the local map of the keyframe.

Thanks, I'll post here if I have any more queries in the future or if I make some progress.
