RIEGL VMR

Product catalog summary

Overview: The RIEGL VMR is a compact and robust robotic solution designed for railroad surveying applications. It integrates the RIEGL VZ-400i laser scanner to provide high-resolution scan data, capable of performing up to 50 scans per hour in Stop & Go mode. The system automatically registers scanning positions with high precision and can optionally capture high-resolution calibrated photos.

Typical Applications: The RIEGL VMR is used for high-detail surveys in construction site operations, verification of rail clearance, establishing rail infrastructure information management maps, and surveying railroad tunnels and subways.

Technical Specifications: The system weighs approximately 60 kg and includes a rechargeable lithium battery with a capacity of 16 Ah / 44.4 V, sufficient for one workday. It consumes 70-100 W of power and can be set up in less than 30 minutes. The system operates in automatic Stop & Go mode, performing laser scans every 7 meters. It supports adjustable track gauges from 1,000 mm to 1,435 mm and has a total height of approximately 2 meters. The laser scanner offers a pulse repetition rate (PRR) of up to 1,200 kHz and a maximum measurement range of 800 meters.

Performance and Features: The VMR system stops every 7 meters to take over 20 million measurements with millimeter precision in one minute. It can operate at a maximum speed of 1.5 m/sec. The system provides a homogeneous point density distribution due to its stable integration and consistent central position on the track. It includes an optional camera system for high-resolution photos and a lighting system with four LED lights for dark environments.

Operational Details: The operator's role is primarily observational, with the ability to check registered scan data on a mobile device. In case of unforeseen events, the operator can stop the platform using a remote emergency command. External control points and RTK GNSS can be used to verify and enhance data quality.

Field Test: A field test conducted on September 3, 2022, demonstrated the system's capabilities, with data acquisition lasting 1 hour, 14 minutes, and 22 seconds over a distance of 386 meters, with scan positions every 7 meters.

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. Robotic Rail Laser Scanning System Typical Applications • High Detail Survey in Construction Site Operations • Verification of Rail Clearance • Establishing of Rail Infrastructure Information Management Maps • Surveying of Railroad Tunnels and Subways
