Cloud control control point and best practices

[crullier]

Hi there guys I recently started using Cyclone field 360 with our BLK and have been making the transition from recap mobile which we used in the past.

Without having a bring a surveyor onsite to support our scanning activities does any know if we can use the P2P capabilities of a Leica S910 to shoot some virtual points or target on-site and bring those into Cyclone BLK - just to have "some" sort of control?.

I was also watching some videos from Andy on registering point clouds. Is it a must to close all links or "close the loop" when linking point clouds?
I would think that this would be difficult to accomplish when scanning interiors of a building for instance or a site with many obstructions?

we recently scanned a 12 SF warehouse that was pretty empty. My hunch initially was to start at one corner and work my way around, but I am wondering if a better strategy would have been to start at the centermost spot and then to back to the edged and take some filler scans (which you need with a BLK for instance due to the limited range)

PS: How are you guys scanning multiple floors and making sure your point clouds line up vertically?
Thank you and sorry for all the questions bundles

You might be able to setup a weak control using a plumb bob and disto via placing a target between the flights in the stair core on each level. This is hardly a robust target network though.

Loop closure is important, but seeing as you're not using control I'd say it's critical.

I definitely recommend hiring a surveyor to establish control. You'll be able to find a few nearby via the trade locator.
