-To align multiple scans in PhoXi Control Application, it is useful to use marker patterns.
+Marker space can be used to align multiple scans from PhoXi 3D Scanners. Please refer to [https://www.photoneo.com/files/manuals/PhoXiControl1.2-UserManual.pdf Appendix 1 - Marker Space] in PhoXi Control 1.2 - User Manual for complete information on what marker space is and how to use it correctly.

-The marker patterns are able to comfortably cover the whole scanning range of the PhoXi 3D Scanners. For cases where the size of the pattern has to be scaled, the scale of the printed pattern has to be reflected as corresponding setting in PhoXi Control.

 ==How to create the model of the object==
-# Put the object above the marker plate and switch the coordinate space to Marker space. You can now move the scanner to different locations, it always returns the point cloud in the same coordinate system defined by marker plate.
+# Set up Marker space in PhoXi Control.
 # Make several scans from different angles to capture the object from all sides. Save each scan to PLY file.
 # Open all PLY files in 3D point cloud viewer, e.g. Meshlab or Cloud Compare, crop the desired object, use some fine alignment algorithm (ICP), merge the point clouds and polygonize it to create a surface model.

 # Open PhoXi Control App and connect to the scanner
 # In the options pane on the left, check following options in group Coordinates:
 #* CoordinateSpace = MarkerSpace
 # Put marker plate in the view of camera. Make sure camera sees at least four marker circles, then trigger the scan. Point cloud will be returned in coordinate system of marker plate.

 For PhoXi 3D scanners model XS, it is recommended to print the A4 marker pattern scaled at 50% and use the following utility to change the detection of marker pattern: [http://photoneo.com/files/utils/SetMarkerSettings.rar utility].

 For PhoXi 3D scanners model M and S usually the A4 size marker pattern is sufficient.
