7 SYSTEM VEC FILE
7.1 MEANING
The internal VEC file which is inside the system is dedicated to every system. It gathers the calibration
parameters. This file cannot be exchanged with another one or modified by any one.
Usually, this file is produced by VIAMETRIS team and as no reason to change but in case of shocks or
physical changes in the sensor unit.
7.2 HOW TO UPDATE IT
In case VIAMETRIS team send a new VEC file, the user is able to update it through the tablet:
 First switch-on the system and the tablet
 Wait for the connection between the system and the tablet
 Enter the configuration window
 Update configuration file and select the new file
8 USAGE RECOMMENDATIONS
8.1 SITE PREPARATION
 Inspect scan surface, make sure to scan in an even floor or less rough as possible to prevent
from unexpected vibration
 Scout your scanning area to anticipate your trajectory.
 Open each door to facilitate your scan.
 Lit up each room to ensure a good camera shooting
 Ensure proper access to all rooms and areas targeted (key locks, pin locks) as well as the
room’s availability for scanning operations. (Meetings…)

Further recommendations about scout’s role and trajectory are provided in the next section 8.2
8.2 OPERATIONAL RECOMMENDATIONS
iMS3D is a highly performing system using state of the art technology components. Nevertheless there
are some basic precautions to be undertaken considering:
- The Hokuyo® profilers are designed for indoor measurement, direct sun light will decrease the
measurement ranges.
- Ladybug® camera works with a shutter time and going through different light conditions will
produce either dark or white images during transitions.
- Central Hokuyo® profiler needs to scan vertical features.
- Despite highly sophisticated algorithms, measurements can be altered by wrong scanning staff
positioning (see section on Scout 8.2.1)
Therefore, it is key that the following operational recommendations are implemented as they are
critical to obtain optimum measurements.
