Description

**Describe the bug**
It seems that Open3D's Reconstruction System handles sequence data (all RGBD images are a continuous sequence) by default - eg. make fragments. When I using Open3D to process several sequences but captured in the same place, the reconstructed scene is jumbled (the result is below). Does Open3D has function or parameters about offline reconstruction. Or maybe I missed something?

**To Reproduce**
Steps to reproduce the behavior:
I use the data from [4 scenes dataset](http://www.graphics.stanford.edu/projects/reloc/), Kitchen, Apartment 1.
cd './Open3D-master/examples/Python/ReconstructionSystem'
python 'run_system.py config/4scenes.json --make --register --refine --integrate'
See error:
