GRP IMS5000 Tunnel Scanning System
IMS5000 adds inertial navigation module on the basis of GRP5000, and records line track while scanning, which can quickly and efficiently complete the three-dimensional data collection of track and surrounding structures, buildings (adjacent track, tunnel, overhead line, etc.) information. In addition to all the function modules of GRP5000, the system can also be used to fit the central coordinates of shield tunnel, the central coordinates of line, identify the height of overhead line, and identify the information of the approach rail head.IMS5000 collects real 3d data and can also be used to provide data foundation for 3d information visualization, virtual reality and BIM modeling.

Fitting The Tunnel Center Line
The central coordinates of shield tunneling can be automatically fitted and extended to CAD drawings，which can be used as the results of planning and completion acceptance.
Track Center Line Coordinates
The center line coordinates can be automatically generated and expanded into CAD drawings, which can be used as the results of planning and completion acceptance.
Height and Pull Out Value of Contact Network
It can automatically identify the contact network, generate the height and pull out value table and generate CAD format file
Identify the Rail Head Information
It can automatically identify the rail information and output the rail gauge, the rail line center coordinates and other parameters. It can identify the third rail and generate the position information of the third rail.
3d Visual Virtual Reality
The 3d absolute data collected can be browsed in the software and can be exported to point cloud of various common formats for virtual reality, BIM modeling and so on.
