Fast, rugged, highly-accurateAreas of application Key characteristics Laser scanning principle· Clearance analysis- Analysing the whole infrastructureand thesurroundings of the driventrack axis- Analysing tunnels/tunnelwalls- Analysing platform edges- Detecting clearance infringements- Testing railroad clearanceswhen operating oversizedloads· Inventory survey (2D/2.5D/3D)· Documentation and analysis ofthe railroad network/system· Ballast profile documentation· Creating a planning basis forreconstruction work ordeployment of newtrains/vehicles· Full 360 ° field of view(no shadowing effects)· Doubled laser scanperformance due to theintegration of two laserscanningsystemssynchronized in a single casing("single device design"):- 500 rot./sec., i.e.cross-sections (effective)- Data acquisition rate of1,016,000 pixel/sec.(effective)· User-definable horizontal andvertical resolutions· Interfaces for synchronizationwith navigation sensors· Ethernet interface for datatransfer and communication· Extreme high ruggedness andstability due to its compactarchitecture· High security level (et al. safetycover for the rotating laserheads, emergency-stopmechanism, laser safety class3R)· System adaptable to customerrequirementsIn order to take measurementsalong a specified track, theZ+F PROFILER 6007 duo must bemounted onto a carrier platformof a moving vehicle. The twointegrated laser scanning systemsmeasure helix-shaped scanlines of the surrounding surface.A measurement consists of anangle and a distance which isdetermined recording the phasedifference between emitted andreflected laser beam.The rotation speed of the twolaser scanning systems and thevelocity of the carrier vehicledefine the density of measurements(vertical and horizontalspacing between scannedpoints).Source: Amberg Technologies3
