1. Preregistration

1a. Automatic Preregistration

Target-free

This function is a very effective and fast procedure that preregisters a set of scans automatically, without using targets or markers.

Target-based

This function automatically registers a set of scans by detecting and matching targets (planar or spherical ones). The user can start the automatic target detection, otherwise can manually add, move and remove targets. 


1b. Manual Preregistration (among models)

This function allows you to manually compute a rough alignment between two generic models. The procedure works by finding three couples of corresponding points among the reference and moving models.

A particular case of this command is the registration between two  grid point clouds (see Manual Pre-registration among grid point clouds).



Note: in the target-free automatic preregistration process there's a possibility to use a sketch to aid the computation, suggesting the relative position of the scans (see Sketch Window)
