Mirrors:
 Rooms or areas with mirrors on one side are not requiring special scanning handling but will
create ghost image that would require to be managed during post production.
 Multiple mirrors can create artefacts that could be difficult to correct during post production,
it then recommended to “hide” facing mirrors if they can reflect on each other’s.
 It is then recommended to first try and test system reaction when passing by mirrors. If
required hiding some mirrors (paper rolls…) can improve the scan.
8.2.4 DOORS: HOW TO HANDLE “OPEN/CLOSE”
 Doors separating areas and rooms have to be carefully handled during the scanning operation:
 It is always recommended to slow down the scanning process while entering in a new room,
especially while stepping through the door step. See Figure 23.
 Failure to do so could reduce the accuracy of the door step measurement which is always
considered as a very critical point.
Figure 23: to be sure to capture all critical door step details, it is recommended to slow down the walking pace while crossing
door steps
Opening of doors
 If the cart operator is opening the door, it is recommended to follow the sequence:
o Operator approaches the door moving backward and handles the opening from his
back: Figure 24
o Operator slowly walk backward through the door step pulling the cart behind him
Figure 25
o Operator resumes normal scanning process pushing the cart in front of him
