A modern and efficient measuring system for clearance analysis, Trimble GEDO Scan consists of the Trimble GEDO CE 2.0 track measurement trolley with a Trimble control unit in combination with a laser scanner.
The purely relative kinematic scan system is suitable for all clearance analysis where only the relative perpendicular distance between objects and the current track position has to be determined.
The system can be used in combination with the Trimble GEDO GX50 as well as with classics terrestrial laser scanners such as the Trimble TX8.
Versatile
Trimble GEDO Scan can be used with GEDO Rec and GEDO IMS systems
Multiple applications
The combined data produce detailed 3D models of tunnels, overpasses, stations and other facilities where precise information is needed for railcar clearance and asset management.
Two operation modes
The Local mode is for track clearance analysis capturing information based on the offset from the rail to nearby objects. In Absolute mode, the system can create 3D point clouds and tie objects to the rail as well as defined coordinate systems.
Visualisation and analysis
For railway specific 3D visualization and analysis, Trimble GEDO Scan Office 2.0 uses clearance envelopes and 3D models to simulate the movement of a railcar through an existing facility or stretch of track. The system can automatically detect locations where clearance encroachments may occur. For detailed analysis, Trimble GEDO Scan Office 2.0 can create cross section drawings and compare differences according to given profiles or envelopes.
The Trimble GEDO Scan system utilises a Trimble TX8 or GX50 (single or dual head) 3D laser scanner to collect high-resolution datasets of 3-dimensional points. The scanner is mounted on a GEDO trolley, which collects location, gauge and cant information as it is moved along the track. The combined data produce detailed 3D models of tunnels, overpasses, stations and other facilities where precise information is needed for railcar clearance and asset management. The Trimble GEDO Scan Office 2.0 software combines data from the GEDO Scan and GEDO Rec field operations to produce a 3D point cloud.
• Simple, self-contained trolley used for Trimble GEDO Scan and other track
measuring applications.
- Helical scanning mode captures ceilings and walls to produce accurate 3D data for modelling tunnels and overpasses.
- GEDO Scan Field software runs on the Trimble Tablet rugged PC controller. The software controls scanning operations and data collection from the scanner and trolley.
- Modular system lets you use the Trimble TX8 or GX50 3D scanner for other survey and facility needs.
- Workflow and user interface are consistent with other GEDO systems to reduce training and increase system productivity.
- Supports 80° Mode for better object visibility at as-built scans.
- Neighbour track detection out of the scanning data to survey the scanned but not surveyed track.
- Chainage view for easy navigation within the point cloud.
