VMR Terrestrial Laser Scanning System On RIEGL USA, Inc.

The RIEGL VMR is an extremely compact and robust robotic solution for railroad surveying applications.

The sensor part of the system, a RIEGL VZ-400i laser scanner, provides high-resolution scan data. In Stop & Go mode, it performs up to 50 scans per hour. These single scanning positions are registered onboard, with high precision and fully automatically.

Optionally, high-resolution calibrated photos are taken in parallel. The georeferenced point clouds are then prepared for exportation to dedicated third-party rail processing software packages.
