Despite being lighter, the second generation offers all the same technological capacities as its predecessor, but is simpler to use and can be mounted on a vehicle in just minutes.
A complete new design
The system component (including the sensors) and the element to fix the device to the vehicle (the frame) previously formed one unit, but are now separated. The system, which has been completely redesigned, is now much lighter (9kg) and more compact.
The mechanism to fix the scanner to the vehicle, which formed part of the system in the first-generation version, has been entirely transformed. A completely rigid metal frame, fixed onto two roof bars, now holds the system, which fits into a dedicated compartment in seconds. As the frame is totally rigid, this limits all vibrations between the system and the vehicle and thus prevents any strain on the mechanics during acquisition.
The second auxiliary antenna, which measures the heading by satellite, is discreet and non-removable, and fixed directly to the vehicle chassis.
This new design makes it easier to mount and use the system
Light (9kg) and compact, it only takes one person to mount the system and this can be done in under three minutes in a configuration where the frame remains permanently fixed to a dedicated vehicle. Furthermore, the alignment phase takes place the first time the system is mounted and does not need to be repeated. This saves valuable time each start.
A whole host of technological features
The vMS3D comprises a new set of components which are more robust and stable in difficult conditions.
- The integrated connectors are next-generation and embedded-grade
- The control box for power supply and communication with the tablet has been moved inside the vehicle to offer increased comfort to the user

Viametris: at the heart of SLAM technology
For over ten years, Viametris has been a pioneering company thanks to its capacity to innovate and evolve its algorithms while offering mobile robotic technologies. The company has developed a unique, hybrid approach which brings together IMU (Inertial Measurement Unit), GNSS and SLAM (Simultaneous Localisation and Mapping) to respond to all the constraints that might skew a trajectory.
- The IMU can independently calculate a trajectory, but over a short period.
- The satellite positioning has long-distance coherence, but the slightest obstacle (tunnels, urban canyons, trees, etc.) disturbs the signal. In the event of outage, the IMU filters the signals for a limited time, but the position deviation increases by time.
- The SLAM is autonomous, using keypoints in the environment. However, the deviation increases by distance.
Viametris’s hybrid approach, which is unique on the market, offers an uninterrupted trajectory computation which is also more accurate, and it does so by making IMU, GNSS and SLAM work together. Regardless of technical or environmental constraints, this trio makes it possible to obtain a precise trajectographic measurement.
