Results saved before doing global bundle adjustment

[gsp-27]

Hi,

First I want to thank you for the amazing codebase for SLAM. I had a question: why are the reconstruction results saved before terminate and multiple bundle adjustments that are performed in terminate?

DROID-SLAM/demo.py

Lines 131 to 134 in 8016d2b

	if args.reconstruction_path is not None:
	save_reconstruction(droid, args.reconstruction_path)
	traj_est = droid.terminate(image_stream(args.imagedir, args.calib, args.stride))

Thanks
