If a project can not cover all necessary areas to scan without moving the object relative to the surface 

with  markers, you  need  to  create  multiple  projects  (by  number  of  positions  of  the  object  relative  to  the 
markers) and then during the processing load them together to combine. 

Markers  should  be  attached  as  chaotic  as  possible.  Avoid  expressed  patterns  or  curves,  as  this  may 

provoke  incorrect  detection  of  markers.  If  the  new  fragment  is  not  correctly  oriented  in  relation  to  the 
model, delete it to create a next scan.  When using auxiliary surface, object should not move in relation to 
the markers during the scan! 

If there are not enough markers on the new scan (less 

than three) or the software is unable to joint scan to 
already existing ones, an error message is sent and the 
scan is considered to be unsuccessful.  Also, an error may 
occur if the scanner was decalibrated and can not 
properly assess the size of the markers. 

Brightness of the projector light when identifying 

markers can be changed.  Turn on the illumination mode 

Markers 

and open the 

Brightness settings. 

Specify the 

brightness value, at which the markers can be clearly seen 
on the output from the cameras. 

When creating project with markers, it is necessary to 

specify the type and size of used markers. Scanner kit 
includes black markers with radius of 2.5 mm. 

Sequence of actions when scanning with markers: 

●

 

Stick markers on the object or auxiliary surface 

●

 

Prepare the surface of the object to be scanned (if needed) 

●

 

Create new project

 with markers or open an existing one
