雷射道路影像檢測系統

Laser Road Image System, LRIS

PAVEMETRICS’s laser road imaging system (LRIS) is composed of two high resolution linescan cameras andlasers that are configured to image 4m transverse road sections with 1 mm resolution at speeds that can reach 100 km/h. This patented imaging system was,designed to increase the contrast and visibility of both small longitudinal and lateral road cracks.

The LRIS optical configuration increases the visibility of even the smallest cracks by using the incident illumination angle of the laser to cause the cracks to project shadows.

Using high power laser line projectors and advanced optics, the LRIS system is very robust to variations in outside lighting conditions and shadows cast by roadside objects, viaducts and the inspection vehicle itself.

KEY FEATURES

雷射道路路轍量測系統

 Laser Rut Measurement System, LRMS

Pavemetrics’s laser rut measurement system (LRMS) is a transverse profiling device that detects and characterizes pavement rutting. The LRMS can acquire full 4-meter width profiles of a highway lane at normal traffic speeds, with 2 options of maximum sampling rate: 30 or 150 Hz. The system uses two 3D laser profilers that digitize transverse sections of the pavement with 1280 points.

Custom optics and high-power pulsed laser line projectors allow the system to operate in full daylight or in night-time conditions. Road transverse profile data can be collected and processed in real time on board the vehicle. Rut extraction algorithms have been developed to automatically measure rut depth and width.

The system is delivered with a complete DLL library of C/C++ functions allowing the user to easily configure the sensors, acquire transverse profiles, extract road rut data, classify rut type (short, multiple, long radius) and validate the laser profiler calibration. Over the past years, this system has been used on a continuous basis by dozens of governments and private agencies. Hundreds of thousands of road kilometers have been surveyed using this technology.

雷射道路裂縫量測系統

 Laser Crack Measurement System, LCMS

The laser crack measurement system (LCMS) uses laser line projectors, high speed cameras and advanced optics to acquire high resolution 3D profiles of the road. This unique 3D vision technology allows for automatic pavement condition assessment of asphalt, porous asphalt, chipseal and concrete surfaces. The LCMS acquires both 3D and 2D image data of the road surface with 1 mm resolution over a 4 m lane width at survey speeds up to 100 km/h.

LCMS data is acquired and compressed in real time in the survey vehicle so as to minimize storage needs (<1Gb per km). The collected data can then be analyzed using Pavemetrics data processing toolbox (DLL library of C/C++ functions). This library has functions to detect and analyze cracks, lane markings, potholes, ravelling, and macro-texture. Rutting is also measured and characterized using more than 4 000 points and rut depth and type (short, multiple, long radius) is evaluated.

Concrete road surfaces can be scanned to evaluate joints, tinning and faulting between the concrete slabs.IMUs can be added to the sensors in order to measure longitudinal profiles, IRI, slope and crossfall.

KEY FEATURES

  • Automatic crack detection and severity

  • 4 160 point rutting (rut depth, rut type)

  • Macro-texture measurements over 100 % of the lane width.

  • 3D and 2D data to characterise: cracks, pot holes, ravelling, sealed cracks, joints in concrete, tinning, etc.

雷射跑道鋪面異物偵測系統

 Laser Foreign Object Debris Detection System, LFOD

The laser foreign object debris (LFOD) detection system uses high speed cameras, custom optics and laser line projectors to acquire both 2D images and high resolution 3D profiles of airport runways, taxiways and aprons in order to automatically detect even the smallest objects at highway speeds.

The LFOD system can be operated both during daytime and nighttime as well as under all types of lighting conditions. Sun and shadows as well as various pavement types ranging from dark asphalt to concrete can be scanned at inspection speeds from 0 to 100km/h. Depending on the configuration selected, an entire runway can be scanned in only a few minutes; automatically detecting FOD as small as 2 mm in size.

FOD and GPS data is collected simultaneously and is analysed in real-time. Alarms can be pre-set to trigger upon detection of FOD of specific sizes or volume. Included software reports size, number and location data for each of the detected debris; thus allowing operations and maintenance personnel to quickly decide whether to remove individual threats or to proceed with a general runway maintenance program.

KEY FEATURES

  • Detection of FOD as small as 2mm

  • 24 hour operation; day and night-time

  • Automated detection; alarms can be pre-set to trigger upon the detection of specific FOD sizes

 雷射隧道斷面掃瞄儀

 Laser Tunnel Scanning System, LTSS

The Laser Tunnel Scanning System (LTSS) uses multiple high speed laser scanners to acquire both 2D images and high resolution 3D profiles of tunnel linings.

This system can scan a full tunnel vault (24m) at 1mm resolution image and 3D data at acquisition speeds up to 20km/h. Once digitized the tunnel data can be viewed and analyzed offline by operators using multi-resolution 3D viewing and analysis software that allow the high precision measurement of virtually any tunnel feature. Automatic analysis software is available to detect and rate the condition of joints, faulting, cracks, degraded concrete, wet as well as wet and humid area tunnel linings.

The LTSS technology was used to scan high speed TGV rail tunnels such as the 28km long Spanish Guadarrama tunnel in full one millimetre resolution (x,y,z) in just 3 hours. The system was also used to acquire data on the Tokyo Metro System in Japan. Vaults are scanned one half going forward and the second half coming back.

The LTSS is one hundred times faster and 10 times more accurate than typical LIDAR technology. The LTSS can acquire 120,000,000 3D and 2D image points per second at an accuracy of 0.5 mm compared to typical LIDAR accuracies of 5.0 mm for just a few 100,000 points. The standard LTSS configuration (6 sensors) allows for the scanning of a full 12 m of tunnel surface perimeter in a single pass. Larger surfaces can be captured through multiple passes (and the images and data stitched) or scanning width can be increased through the addition of sensors.

KEY FEATURES

  • Full vault scanning.

  • 1mm resolution images and 3D data.

  • 100 times faster and 10 times more accurate than lidar scanning.

  • Measure tunnel features with sub millimeter accuracy.
