Importing positioning targets
It is possible to import previously acquired positioning model in ZScan. From the
1.2 version, it will now be possible to import positioning features acquired by the
ZScanner 700 or by a photogrammetry system. Please note that ONLY
ZScanner 700 TARGETS CAN BE RECOGNIZED. Any other type of reflective
target will not be usable in ZScan. Files to be imported must be composed of
three columns (X Y Z) separated with a SPACE. The three columns represent
the center of the target.
Imported targets will then appear as spheres as ZScan cannot know in which
direction they are. He will use the center to recognize the patterns and add the
normal when scanning.
Acquiring data
To start the scan, click scan - Record Scan or click on in the toolbar.

Take the ZScanner 700 in one hand and position at about 300
mm (12 in) away from the object.

To have the laser cross displayed on the object at any time,
press the preview button on the ZScanner 700 (see figure 1.1)

To launch the scan, press the trigger button on the ZScanner
700 (see figure 1.1) Sweep the object surface while holding
down the trigger button.
TIP: Darker surfaces will need more laser power and/or longer shutter
time. However, longer shutter time will catch more noise. It is
recommended to increase laser power first and increase shutter

The object can be moved during digitizing without altering data
acquisition as long as the reflective targets are affixed on the object.
TIP: The quality of the results will be directly influenced by the number
of times and the speed with which the surface is swept. The more you
sweep the surface, the more accurate the results will be.
