LiDAR technology has been common in geographical surveying for many years and is applied in similar ways to road surveying. The system uses a rotating laser that records distance to build up a three dimensional picture of the roadway and surrounds.
Digital imaging has limitations in terms of measurement accuracy, due to the resolution of cameras. LiDAR collects extensive point cloud information to build up a very accurate simulation of the road and roadside environment.
The device can be mounted at any position on the vehicle, in any direction, to suit the client’s requirements. This flexible positioning allows the unit to collect objects above and to the side of the vehicle, or facing the road for linemarking detection.
The data is then processed instantly within the Hawkeye Processing Toolkit software, allowing for review in conjunction with other collected parameters.
Applications:
- 3D mapping and visualisation of road corridor
- Accurately measure roadside objects
- Bridge height measurement
- Gantry height measurement
- Lane width measurement
- Hazards offsets (safety)
