MULTIFUNCTIONAL 3D LASER ROAD AUSCULTATION
The safety of users and the preservation of the road heritage are the major concerns of the network manager.
The implementation of a rational and effective management approach requires in-depth knowledge of the characteristics of the infrastructures.
Covering a vast area of expertise, these different types of data can be collected at high efficiency by the very latest generation of multifunction auscultation equipment.
Whether creating a road database, updating management systems as part of safety studies or work proposals, these systems provide the precision, productivity and versatility required.
This tool makes it possible to quickly COVER hundreds of kilometres to determine the indicators commonly used in this investigative framework.
CONSTITUTION AND CHARACTERISTICS
The proposed technical solution implements the LCMS system « LASER Crack Measurement System » from the PAVEMETRICS company, of which VIAPIX Systems is one of the certified integrator partners.
This very high-tech measurement system is controlled by a VIAPIX Acquisition module which provides measurement supervision and control.

All the indicators are imported into the database specific to the VIAPIX system and can also be exported as text files in CSV format, or as GIS layers.
HARDWARE
LCMS Sensors
-
-
- 2 x LASER Class 3 B (IEC 60825-1 2001) – Wavelength 808 nm (IR)
- Case: IP65
- Sampling frequency 11 200 Hz
- Weight: 10 kg per sensor
-
Option IMU
-
-
- Accelerations: ± 5g
- Case: IP65
- Sampling frequency: 150 Hz
-
With a robust design and having connectors adapted to harsh environments, the LCMS sensors are installed on a support fixed to the vehicle. The geometric arrangement of the laser sensors as well as a rigorous calibration of the assembly condition the quality of the fusion of the data from the two sensors.
