that a majority of detected laser points are included in the reliable zone (yellow). If the
laser lines are underexposed, they will not be detected entirely. On the other hand, if
laser lines are saturated, there will be a lot of noise in the resulting scan and the laser lines
will not be detected precisely.
It is possible to adjust the parameters through the two sliders at the bottom of the dialog.
The Laser Power slider controls the output power of the laser. It is expressed as a
percentage of the peak laser power. A higher value will result in less points being
underexposed. The Shutter slider controls the exposure time of each frame and is
expressed in milliseconds. A higher value in that slider means that more light will come
from the laser line, and it will appear more saturated.
The Auto Adjust tool will adjust the scanner parameters and find which parameters will be
optimal for the object the user is trying to scan. This works well if the laser lines are entirely
contained within the object to scan. It can be used as an initial approximation if the laser
lines are only partially enclosed within the object to scan.
The Save button can be used to save a template of parameters, which can later be
loaded with the Open button. It can prove to be useful when scanning similar objects.
Sensor parameters can be restored to their default setting by hitting the Default button. It
is possible to reset the parameters to what they were before opening the sensor
configuration tool by hitting the Reset button.
Sensor Manager
At the end of the installation process, or at all times after that, it is possible to access the
sensor manager in order to manage the configuration and license files for your scanner.
This utility is available through the menu Configure | Sensor Manager.
The figure below shows the main sensor manager window. The main feature of this
window is the Sensor list, which include all the sensors installed on that particular
computer. It is possible to install more than one scanner on the same computer, as in the
example below. The Configuration and License columns show the status of the
configuration and license files for one particular scanner. If the files are correctly installed,
there will be a mark in the respective checkbox.
The column Active indicate whether a particular scanner is currently active. In order to
improve ZScan's loading time, it is possible to deactivate scanners. The improvement in
performance when starting the software will be most noticeable if many scanners are
installed on the same computer. Please note that having many active scanners won't
impact on ZScan's scanning performance.
In the example below, the scanner OK is installed correctly and is currently active. The
scanner Inactive is correctly installed, but cannot be used as it is currently deactivated.
The scanner NoConfig cannot be used as its configuration file is missing and is therefore
inactive.
