Device Registration Methods
Registers the position of connected devices or aligns scans into one coordinate system with various registration methods.
The following table shows how the each registration method calculates a transform matrix from scans.
Spheres
After detecting the center point of spherical features from scans scanned from each connected scanner,
calculates a transform matrix so that the distance between the corresponding reference points is
minimized, and then uses the transforms for registering the position of the devices or for aligning scans
into one coordinate system.
Note: To register the position of connected devices with the Spheres registration method, an object
requires to be positioned so that at least three spherical features can be matched between scans
and must be visible in the camera view of each connected scanner while setting up the device
registration.
Best Fit
Calculates a transform matrix by aligning scans scanned from each connected scanners with the best-fit
alignment method and uses the transforms for registering the position of the
devices
or for aligning scans
into one coordinate system.
Target Markers
After detecting target markers from scans scanned from each connected scanner, calculates a transform
matrix so that the more than four scanned target markers can be matched, and then uses the transforms
for registering the position of the
devices
or for aligning scans into one coordinate system.
Note: To register the position of connected devices with the Target Markers registration method, an
object requires to be positioned so that at least four target markers can be matched between scans
and must be visible in the camera view of each connected scanner while setting up the device
registration.
Note: When using the device registration methods, refer to the tips below:
•
Prevent the scan floor from being captured in a scan
•
Apply white scanning spray or powder evenly and make sure an object is adequately covered
•
Dim the lights
•
Use proper sized target markers

Current Location
- Registers the position of connected
devices
by using the transform matrix calculated from the last scan
alignment. If you already have scans aligned with the other alignment methods provided in your Geomagic application, you can
update it to the Geomagic Capture.
Register
- After scanning an object with the selected registration method, and then uses the transforms for registering the
position of connected
devices
or for aligning scans into one coordinate system.
