Laser Inspection for Road Asset Management
Roads represent huge government investments and require periodic maintenance to keep them fit for purpose and mitigate deterioration.
Preventive road maintenance is the best way to conserve this infrastructure. Considering the resource constraints to carrying out road maintenance, governments need to allocate funds and resources in the best way possible.
To do this, it essential to assess the roads’ condition. Conventional road surveys are costly, time-consuming, and suffer a lack of repeatability and reproducibility.
But, using a vehicle-mounted point laser scanning system, you can have automatic road condition measurements at less cost.
Avestron’s Multi-Function Road Index Detection System can rapidly collect high-precision 3D point cloud data and grayscale data of the pavement.
This permits 3D modeling of the pavement according to the data and enables autonomous analysis and extraction of pavement distresses. It can detect 33 indicators such as pavement distress condition, rutting depth, surface unevenness, roadside facilities, and texture depth. It also offers complete sets of detection solutions to expressway, classified highway, urban roads, rail detection, and airfield pavement.
Avestron Road Inspection systems are powered by Intellectual Property from ZOYON Science and Technology Co., Ltd. and manufactured by Avestron in Canada.
Vehicle Mounted Laser Scanner for Road Deterioration Detection
Vehicle Mounted Laser Scanner System Components
2D PAVEMENT IMAGE DETECTION
Using a high-definition 2D image of correlation-illumination eliminates interference caused by roadside assets and vehicle shadow.
3D PAVEMENT IMAGE DETECTION
Creates a high-precision 3D point cloud of the pavement and subdues environmental disturbances such as natural lighting, shadow, oil stain etc.
CROSS SECTION DETECTION
Makes measurements with a width of 3.6 m (non-discrete point analog) with a detection accuracy of 0.1 mm based on sub-pixel segmentation technique.
VERTICAL SECTION DETECTION
Performs tests under complex road conditions such as sudden stop, sudden start, change speed, horizontal and longitudinal slope and turns. Analyzes the smoothness of the road based on the surface contour.
Counts the number of road assets using GPS based and binocular photogrammetry and generates high resolution true color images.
ROAD GEOMETRY DETECTION
Cross slope, longitudinal slope and curvature.
PAVEMENT LAYER THICKNESS AND PIPELINE DETECTION
Pavement layer thickness and pipelines.
GEOGRAPHIC LOCATION INFORMATION DETECTION
Latitude and longitude, altitude and station.
