3D Laser Mapping Launches Telecom Mapping System
3D Laser Mapping has launched a mobile mapping system designed to capture
asbuilt 3D measurements of overhead telecom networks. The vehicle-mounted
WireFinder system uses laser technology and specially designed software to
measure the position of telecom network assets, such as poles and wires.
The WireFinder uses a Riegl 3D laser scanner controlled by software developed
for this application by 3D Laser Mapping. The positions of telecom network
assets are measured with laser beams. An integrated satellite positioning
system enables these measurements to be georeferenced to real world
coordinates, making the resulting data suitable for use in a GIS environment.
The system is used while stationary, making the WireFinder solution safer than
existing systems where survey staff have to stand in the road while recording
measurements.
WireFinder has been developed in direct response to demand from telecoms
maintenance operators in Europe and the USA. Dr. Graham Hunter, managing
director of 3D Laser Mapping, commented, "We have worked closely with a number
of organisations to ensure the WireFinder meets the specific requirement of
this industry. WireFinder offers a unique and unrivalled technical
specification yet is robust, fully portable, and easy to use." He continued,
"WireFinder complements our existing suite of terrestrial laser scanning
solutions including StreetMapper the high productivity, vehicle mounted mapping
system optimized for mobile data collection."
3D laser scanners capture highly accurate and detailed surface measurements by
transmitting optical pulses that are reflected from the surface or feature.
Using the time taken for each individual pulse to be returned and the known
value of the speed of light, the system can accurately calculate the distance
of the feature from the scanning unit. The WireFinder laser scanner, with its
360-degree field of view, can capture 12,000 measurements per second at
distances of up to 300 meters with a repeatability of less than 10 millimeters.
