SLAM Loop Closure

I created a video for a customer to illustrate proper loop closure techniques and I thought it would be nice to share.



If you are aligning to GCPs in the field, say in a linear environment, do you still need loop closure?

@wallsLANDwater not necessarily. It just depends on how many GCPs you have. Loop closure is just a good way to do cloud to cloud registration and eliminate the need for so many GCPs.
