MEASURING TROLLEY.
LPS
TRACK CLEARANCE PROFILE SCANNER LPS
Track clearance scanner built on the track
geometry and rail profiles measurement trolley
Krab accompanied with the powerful evaluation
software LPS Evaluation suite.
LPS is a track inspection system using two rotating lasers to scan the full clearance envelope, including tunnels, platforms, OH wires, masts, vegetation, and nearby objects.
Mounted on the stable Krab trolley, it also captures full track geometry and rail profiles (with 3D cameras). The system provides enough data to reconstruct a complete 3D track model.
A synchronized camera adds valuable visual context.
The trolley is manually pushed at walking speed (~4 km/h), and data are saved to a USB drive for analysis using the LPS Evaluation software on PC.
EVALUATION SOFTWARE
Dedicated evaluation program LPS Evaluation suite allows to explore Clearance data in great detail in two modes - Static Clearance and Dynamic Clearance which includes widening of the refferential profile in curves.
Both modes can be viewed in 2D Cross section and 3D point cloud.
Built-in evaluation modules provides also detection and evaluation of Platforms and Catenary detects
and provides related reports.
Measured section can be also displayed on the map with indicated reference profile infringements.
