Function
Figure 8. “On-line” scanning mode using PET software
The on-line scanning mode offered by the PET software was
operated using “Import Digitizer One Scan” interface. The
interface window was divided in two parts, namely the view of
scanning object and the scanner controller function (Figure 8).
In the first part, the scanning object from both laser scanners
was displayed. The second part allowed the user to control
both scanners to performed scanning task. If the scanning
project required the used of two VI-910s 3D digitizer system,
the basic information of both laser scanners was shown in the
“Hardware” module (Figure 9 and Figure 10). The setting of
the scanning mode for each laser scanner can also be done using
“Camera 1” and “Camera 2” modules.

Scanner using “Camera 1” and “Camera 2” Modules.
The interface also provided the preliminary scanning accuracy
information by colour coding method (Figure 11). The function
was fully utilized just after the scanning task finished. The
accuracy was early evaluated using the colour coding scale
which shows the effectiveness of the scanning on the surface of
the object.
