Find correspondences for scan positions

Mark this checkbox if the position of a scan is known, for example, by a surveyed reference point or by a reference sphere representing the position of the scanner in other scans.

Force correspondences by target names

Mark this checkbox, if you want to force correspondences by target names. The targets in each scan must be named according to their counterparts in the other scans. This feature requires that targets are already detected by SCENE. In Settings > Process, select a target search, then run Process. After that, open the cluster or the scans in Explore. You can then click the target’s names the in structure view and rename them.

Use Checkerboard Normals

If this setting is active, the normals of checkerboards are used for the correspondence search. Uncheck if the direction of checkerboards has changed from one scan to another. For example, if you use checkerboard targets that can be tilted and turned for a precise orientation to the scanner.

Target Distribution Threshold

Sets the limit for registration. If targets are too near to one another, registration will be refused. In this case, lowering the limits gives you a result.
