Vertical Clearance Measurement
Mounted at the rear of the vehicle, the system continuously records clearance measurements as the vehicle passes below a structure at highway speeds. The complete profile of the bottom of the structure is recorded and the minimum measurement is extracted and stored. Using eye-safe class one lasers, the system captures, displays and stores structure and height information at accuracies less than 1 inch.
This information can be included in asset inventory collection and displayed as part of safety and traffic data in both the PathView II and PathWeb browser applications.
