Although underwater applications were the primary goal in the development of the ULS-100 and ULS-500 laser scanners, they are equally capable of high definition imagery and measurement with in-air scenarios.

 

Operating the Laser Scanners in Air

It is important to note that the scanners do not require any additional parts or modification to the hardware to switch between water and air scanning environments. The only difference is a calibration file the scanning software accesses prior to data collection. One calibration file is provided standard with the purchase or rental of the ULS-100 or ULS-500 and the pair of calibration files can be provided upon request.

 

Applications in Air and Water

The bennifit to haveing a single system capable of both in-air and in-water comes down to cost and convenience. Purchaing a single system is less expensive than purchasing a pair of systems and when operating in environments where both in-water and in-air scanning is needed deployment of the laser scanner is far simpler. The ruggedness of the 2G Robotics systems makes them ideal for a wide range of industrial applications when the scanners are to be mounted on robotic vehicles both above and below the water. Additionally, the cost to deploy suites of sensors into an enviornment can be expensive. By providing a single system that can perform both the in-air and in-water portions of the inspection the time required to perform the inspection and the number of deployments required can be reduced.

 

Example applications where these sensors may be used both in air an in the water is:

Sewer inspections, where part of the tunnel is flooded and part is dry.

Gas pipe inspection where compact and rugged inspection equipment is critical

Surge shaft inspections where the top portion of the shaft is dry and the bottom is below the water line.

 

Case Study

The 2G Robotics ULS-100 has been used for the inspection of welds and dents to gas pipeline. The ULS-100 was selected because of the rugged and compact construction of the sensor making it ideal for deployment on a tracked vehicle. Using the resulting scans the client was able to accurately assess the geometry of the scanned pipe sections. Using geometry information for welds and dents clients can ensure that maintanence funds are allowcated only where they are needed.
