Register
Overview
Registration can be done in Cyclone Field 360 on the iPad and also on Register 360 on a laptop/desktop.
Registration is the aligning and linking of scan data together into one complete scan. It is recommended that you do this on the iPad as you scan as a way to verify the data, enabling you to take more scans if you find that there are gaps.
Alternatively, you may also do all your scans at once and use the desktop app to do so, this may be required if battery is limited, extremely large datasets, multiple scanners are being used on a single dataset, or if the alignment tools in the iPad are not working and more manual/precise alignment is required.
Registration Concepts
Setups
Setups refers to any single scan data. Setups can be found in the Setups menu, categorised by whether the are linked or not.
Bundles
All Setups come in unregistered. A registered Setup is one that is linked to another Setup. These groups of Setups are referred to as Bundles.
Links
Links refers to the hierarchy of connections. A Link can be identified by a solid connecting line between two Setups. Links between Setups/Bundles will be automatically generated as you go through the process but can also be manually altered.
Bundles act as a group when being moved and transformed. When aligning two Setups from two different bundles, the entire bundle will be aligned along with the scan.
Creating logical links is the key concept for registration - how Setups are chained together will determine overall accuracy and ease of adjustments. Aim to create Links that have a high amount of overlap so you are certain that the Setups are aligned as perfect as possible.
In the diagram above, [A] links the Setups in in the order in which they were obtained, however 1 > 2 is a weak link as they do not feature much overlap. Something like [B] should be done instead where both 1 > 3 and 3 > 2 are stronger Links with more overlapping data.
Creating a Network of Links
On the iPad, you will only be able to create a linear chain on links. Once on the desktop, you are able to create more links manually or automatically- this is recommended as it will increase the overall accuracy of the dataset.
FIELD 360 (iPad Workflow)
On the iPad, you can only create single links between scans and not a whole network. Using the iPad is still the best option so you can keep track of what has been scanned and what you might have missed and an idea for alignment.
It is recommended you use the functions in the desktop app REGISTER 360, to generate a stronger network of scans.
Application Overview
While you have used Field 360 to a degree to initiate the scans, the bulk of the application functions serves this registration step. The applications interface is as follows:
The main workflow (left to right): Scan, Tag/Annotate and Register
View types of Datasets (top to bottom): Bundles, Setups, Tags/Annotations
Datasets panels for browsing each dataset
Types of views - Map (2D), 360 Photo, 3D Point Cloud Model
Main 3D viewport, use this to pan and orbit around 2D or 3D views
Used in Map mode, this is a plan section, adjust the slider to view all points below a height
Additional view settings, such as for overlaying the grid, point sizes etc.

Pre-Alignment
If you are starting scans using Field360 on the iPad, an option to pre-align will appear when you have 2 or more scans and are adding it to the same project. As Setups come in, you should aim to roughly place the scans in position before Linking Setups together into Bundles.
This is option only appears if you use the iPad to start scans on the BLK360; if you had started scans on the BLK360 and then later import the scans from the scanner to the iPad, the option will not appear.
Automatic Pre-Alignment
When a new Setup is synced, you may opt to [Pre-Align] them. This will automatically orient the newest Setup roughly into position, Setups with lots of overlapping features will usually result in a good pre-alignment.
Manual Pre-Alignment
You may manually move and rotate the scan to if the Automatic Pre-Alignment does not work. Select the scan and with the gumball tool, adjust the scan to align roughly with the other scan.
Sometimes scans from the plan view look very similar. Use the 360° and 3D view to help you identify elements of your scan to assist in aligning.
Linking Setups
When the Setups that you wish to Link are roughly pre-aligned, you can link begin the linking process through the right-most button along the bottom - the Register function. Follow the on-screen prompts at the bottom to select your setups.
You will have the option to further adjust the scan, here you have access to more views via the top left menu button - this will open a drawer with plan, elevation and 3D perspective views to assist in adjustments.
Finally, the [Optimize] button will make very fine adjustments as the final registration. This is the stage to verify the registration using the various views, if it does not look right at this stage, you will have to make further adjustments.
Once you are satisfied,[Create Link] links where possible. The Setups involved will be placed in a Bundle.
Adjusting Links
If you tap on the Register button (bottom right-most button), besides creating links between two scans, you can also edit and/or remove links.
In the Register mode, links can be tapped on to remove them. You can also edit the link which brings you back to the manual alignment process and menu.
Sometimes you need to zoom in to be able to see the link and tap on it.
Export
For smaller projects (<15~ Setups) you may export directly from the iPad.
pageExport from iPadREGISTER 360 (Desktop Workflow)
Jump forward to the 'Process' step and read up to Registration to transfer any iPad data to the desktop application first. Use some of these options to create a stronger network of links.
During the import process, there are some options for auto-creating scans, this is covered in the next article.
However, the following options allow you to manually create or fine-tune links. Simply select two scans and use the options below the software:
Auto-Cloud
If you are confident in the scan data, you may roughly position them and use [auto cloud], if no new links are generated that means that the software was unable to detect good links, in that case, try the options below.
Manual Alignment
Otherwise, once you select two scans, you can use [visual alignment] for the same alignment process as on the iPad, or use the [split view] option to select a minimum of 3 identical points across the two scans to attempt alignment.
