Real-Time automated System for Distress Survey Multi-Function Data Collection.
The automated system for distress survey covers 100% of pavement surface at the transverse resolution of about 4,000 pixels, produces crack map (location & geometries), and classifies longitudinal, transverse, block, & alligator cracks.

The Multi-Functional Digital Highway Data Vehicle.
|
- High resolution digital images for pavement surface and Right-Of Way.
- Automated distress analyzer (ADA, 1mm resolution automated crack analysis).
- Longitudinal and transverse profiling (IRI and rutting).
- Differential GPS, inertial positioning, distance measurement instrument (DMI).
- Multimedia based highway information system (MHIS), report writer.

Incident angle of the Illumination system allows increased visibility of small cracks by the use of the protection of shadows. |
Both data acquisition and processing can be conducted real-time on-board at speed up to 60 MPH.
It applies distress protocols & indices such as the AASHTO protocol, Universal Cracking Indicator (CI), and Texas DOT method.
It is able to detect 1-mm wide cracks.
The INO LRIS combines a line scan camera with laser illumination requiring only 200 Watts.
