Inventory

Road inventory plays an essential role in effective management and maintenance of the road infrastructure. In this process, detailed information about the road network of a region is collected, organized, and analyzed. To carry out this work efficiently, advanced equipment such as FIONA I and FIONA V is employed.

FIONA I and FIONA V are specialized tools designed for thorough inspection and evaluation of roads. These devices use cutting-edge technologies, such as laser scanning systems and high-resolution cameras, to capture precise data about the state of the road infrastructure. From detecting cracks to assessing pavement quality, these devices offer a comprehensive view of road conditions.

When conducting a road inventory with the support of FIONA I and FIONA V, highway authorities can obtain detailed information about road geometry, signage, the presence of potholes, and other critical aspects. This detailed knowledge not only facilitates the planning of maintenance and rehabilitation projects but also contributes to informed decision-making regarding investments and improvements in the road network.

In summary, the use of advanced equipment such as FIONA I and FIONA V in road inventory not only improves efficiency in data collection but also provides a solid foundation for strategic management of road infrastructure, ensuring safe and durable roads for the community.

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.
