How to debug very large numbers after optimization in G2O bundle adjustment?

I have been working on multi-view SFM by reading some research papers. Until now I have only coded the SFM initializer which initializes the 3d reconstruction. The problem is that 3d point numbers after the G2O bundle adjustment are in the millions and billions. Before optimization, the order of points is 10 to 1000.
