Complete and georeferenced cloud points are needed for roadway gauge control in order to take measurements using specific software and, thus, exhaustively control each existing element.
The main phases are:
– Cloud point capture using Mobile Mapping technology
– The identification of bridges and elements subject of study to measure guages.
The technology used to create gauge studies is our Mobile Mapping system, which is pioneer in the capture of massive and dynamic spatial information.
The equipment is mounted on any type of vehicle that allows anchoring. It travels as a conventional vehicle from 5 km/h to 100 km/h, depending on the project needs.
The measurement equipment is comprised of two high-precision laser positioning sensors as well as 4 image collection devices, which have been expanded using the Ladybug 5.0 camera to obtain panoramic images.
The data capture process obtains 1,000,000 points/s in a 180 m length on each side of the vehicle as well as 6 images (360º) every 10 m. It can be modified to suit the job characteristics.
The main characteristic of the system consists of nano-second synchronization between cloud points and the images obtained, guaranteeing the utmost precision and reflecting the reality in order to take measurements with the greatest of precision and accuracy.
The end products may be reflected on cartography, identifying the points where gauge measurements are needed and identifying the maximum and minimum altitudes thereof.
