Chapter Automatic Registration Tools describes how you can run a coarse
, a fine and a target-based registration automatically. The interactive registration tools will help you to quickly edit and fix the results from the automatic registrations. See below some registration workflows combining these tools.
-
Run a coarse and then a fine registration and then use the interactive registration tools to remove wrong connections and then use Update Registration. This feature will also refine the connections and optimize scan positions.
-
Import a Stream project with pre-registered scans, process the scans, and then use the interactive registration tools to add connections (to close the loop, make the registration more robust). Then, use Update Registration.
-
Import a Stream project with pre-registered scans, process the scans, and then use the interactive registration tools to run a correspondence search, which uses the current scan positions. Then, use Update Registration.

Add Connections
-
Click
. -
Then, connect the scans with the mouse.
A new connection is established. In most cases, the new connection will be blue because it has not yet been computed. For example, you can add connections to close the loop in the scan capture. If a new connection automatically turns green after creating it, it had already been computed by a fine registration, but was discarded.
If there are connections with a high error in the Scan Manager, you can also delete them if they are not needed:
-
Optional: click the connection in the structure view or in the registration view, then press the DEL key to delete a connection.
For further information on connections, refer to Connections.
Starting from SCENE 2025.0 scans do not need to be pre-registered in order to add new connections.
Add Correspondence
-
Open the dropdown behind Add Connections.
-
Select Add Correspondence.
Run Correspondence Search
-
Open the dropdown behind Add Connections.
-
Select Run Correspondence Search to run an automatic search for correspondences between scans.
Refine New Connections
Open the Add New Connections dropdown list and select Refine New Connections to compute new connections. Starting from version 2025.0, SCENE will run a coarse and a fine registration on refining connections if the scans were not pre-registered. When the refining has finished successfully, you can use Optimize Scan Positions, see below.
You can still use this feature via this button, but you can also click Update Registration. This feature contains Refine New Connections and Optizime Scan Positions. The reason for providing an extra button for refining connections is that you may want to add connections and then optimize the scan positions, then go back and add more or other connections before you finally update the registration.
Color Coding of Connections
-
Blue: New connections that have not yet been refined are displayed in blue.
-
Green: Connections are green if the scan point error is below the green value specified in the registration settings.
-
Yellow: Connections are yellow if the scan point error is between the green and the red value specified in the registration settings.
-
Red: Connections are red if the scan point error is above the red value specified in the registration settings.
-
Purple: Connections are purple if they were rejected by the scan position optimization due to a big scan point error.
Optimize Scan Positions
Open the Update Registration dropdown list and select Optimize Scan Positions. This computes the optimization of scan positions after you have added and refined or deleted connections. It does not yet change the statistics and takes only a few seconds.
You can still use this feature, but you can also click Update Registration. This feature contains Refine New Connections and Optizime Scan Positions. The reason for providing an extra button for the Optimize Scan Positions feature is that you may want to optimize the scan positions, change the positions and then optimize the scan positions again before you update the statistics. This may be helpful in large projects or if you want to be able to undo the last scan position optimization.
You can undo the last optimization by opening the Update Registration dropdown list and selecting Undo Last Optimization.
Update Registration
If you are satisfied with the previous steps, click Update Registration. This will refine the new connections, optimize the scan positions and update the Scan Manager statistics. This process may take seconds or minutes depending on the number of affected scans.
