Laser Road Imaging System (LRIS)

The Laser Road Imaging System (LRIS) is a high-speed and high-resolution 2D imaging system with proprietary optics designed to increase the contrast and visibility of both small longitudinal and transverse cracks in roadways.

The system uses linescan cameras in conjunction with high-power laser line projectors that are aligned in a symmetrically crossed optical configuration.

The LRIS is capable of scanning a 4 meter width at speeds up to 100 km/h. Two resolutions are available; a standard 1 mm (4,000 pixel) configuration or an optional 0.5 mm (8,000 pixel option) configuration.

The LRIS is designed for users who wish to perform manual distress rating of images or who have developed their own 2D image-based analysis software.

Highway Speed Imaging

Through precise laser and camera synchronization, the LRIS is able to capture crisp and clear high-resolution images of surfaces while traveling at speeds up to 100km/h.

Optimized to Capture Fine Cracking

One of the key advantages of the LRIS system is its optical configuration which includes an optimized incident illumination angle in order to increase fine crack visibility.

Day or Night Operation

The LRIS includes a built-in, high-intensity, laser lighting system which ensures proper illumination whether collecting at mid-day in full sun-light, during dusk and dawn, as well as at night-time.

Automatic Gain Control

Automatic gain control algorithms are used to ensure quality results even under challenging conditions such as when passing under bridges, or changing from new to old road surfaces.
