EQUIPMENT - RAUROS

The assessment of deteriorations in road surveying is carried out precisely and efficiently through the use of advanced technologies, such as the FIONA I and FIONA V systems. These devices are specialized tools designed to measure and analyze in detail the condition of road surfaces.

FIONA I and FIONA V employ state-of-the-art technology, including laser scanning systems and high-resolution cameras, to capture real-time data on the road's condition. This data includes information about the presence of cracks, deformations, irregularities, and other deteriorations that may affect the integrity of the road.

The use of these devices not only allows for the early identification of problems but also facilitates the planning of preventive maintenance interventions. By having access to accurate and up-to-date data, road authorities can make informed decisions to address deteriorations in a timely manner, maximizing the effectiveness of resources allocated to road infrastructure maintenance.

This high-performance vehicle, certified as a laboratory vehicle, is equipped with various integrated systems that, when working together, are capable of conducting a comprehensive assessment of roads.

Vision System

The equipment features an artificial vision system that allows for the acquisition and management of images of the environment in which the vehicle is traveling. The system comprises two cameras: one facing forward in the direction of travel and another camera at the rear of the vehicle to capture signage against the direction of travel. Both cameras are necessary for the subsequent inventory of airport furniture.

Crack Detection System

The equipment includes a crack detection system that enables the acquisition and management of images of the pavement on which the vehicle is traveling. The crack detection system consists of a linear scanner camera and laser illumination, which together continuously collect data from the pavement, allowing the assessment of its degradation state.

The system can detect cracks of at least 1mm in length while traveling at a maximum speed of 80 km/h and capturing a pavement width of 3900 mm. This provides sufficient data for pavement analysis.

Georeferencing System

The vehicle is equipped with a georeferencing system primarily composed of a GPS, an antenna, and the necessary software management for accurate data collection of the system's positioning. Coordinates are acquired using GNSS technology, and WGS84 coordinates (World Geodetic System 84) are obtained.

Inertial System

For data collection related to the geometry of the road under study, the vehicle has an intelligent inertial measurement system for 12 axes with built-in GPS, based on inertial sensors and GPS technology.

The high-performance vehicle FIONA V, certified as a laboratory vehicle, is equipped with 7 integrated systems that, when working together, are capable of conducting a comprehensive assessment of roads.

Vision System

The vision system features a high-resolution spherical digital videocamera equipped with six 2 MP cameras, allowing the system to capture video from over 80% of the 360° sphere. This system utilizes LadyBugCapPro software, which enables the configuration of cameras for proper image acquisition.

Crack Detection or Multiparameter Detection System

The laser crack detection system (LCMS) is a high-speed, high-resolution system with transverse profiling capabilities that can acquire 3D profiles of the complete 4-meter width of a highway lane at normal traffic speed.

Both the resolutions and the acquisition rate of the LCMS are high enough to perform crack detection, macrotexture evaluation, wheel rut measurements, and much more.

Georeferencing System

The vehicle is equipped with a georeferencing system primarily composed of a GPS, an antenna, and the necessary software management for accurate data collection of the system's positioning.

Inertial System

For data collection related to the geometry of the road being studied, the LCMS equipment includes an inertial measurement unit (IMU) within its structure capable of generating all the related information for the study, including radii of curvature, gradients, and superelevations. This system consists of three sensors: accelerometer, gyroscope, and magnetometer.
