Before scanning, set the turntable steps from 8 to 180. The number shows how many times the
turntable will stop in one turn, and the data will get captured at each stop. The default setting, 8 steps,
is recommended. You can change the number of steps according to the features of the objects.
Note: Using more turntable steps will help scan more complete data in some angles, but NOT more
accurate.
6.2.3. Turntable Speed
Set to adjust turntable speed. "6" is set by default. Higher value is with higher speed.
6.2.4. Alignment Mode
Select an alignment mode condition for the turntable scan.
Turntable Alignment
If you do not want to stick marker points on the object you want to scan, and it is too big and covers
the coded targets on the turntable, you could choose turntable align.
Working Principle: Align the data with the assistance of turntable.
Note: Need to keep the distance between turntable and scanner the same as it is during calibration;
Objects in regular shapes such as sphere and square are not suitable for this mode.
Alignment
Marker
The surface of the object requires markers. When the scan starts the markers are required,
otherwise "Track lost" will be displayed.
At least 4 markers captured previously need to be seen by the scanner in each current scanning
frame to be aligned. If not, "Track Lost" will be displayed.
When scanning a large object, Marker Alignment is the best mode at mitigating the cumulative errors
caused by large amounts of data. This results in a higher global accuracy of the complete scanned data
and is the reason we recommend this alignment mode for large objects.
Feature Alignment
When the distance between turntable and scanner is inconsistent with it is during calibration,
feature alignment will be helpful.
Working principle: With feature alignment, after starting scanning, software will capture four data
to calibrate. The scans are matched by knowing the center and angle of rotation between successive
captures.
