VMX-RAIL: Mobile Laser Scanning for Railway Applications

The RIEGL VMX-RAIL mobile LiDAR Mapping System is designed with a triple scanner configuration for integration on a railcar for track mapping and clearance surveying. This rugged design of the measuring head is well suited for long-term operations even in harsh environments. The unique scanner orientation of three high-accuracy VUX-1HA laser scanners allows shadow-free coverage of the area of interest. 3 MHz pulse repetition rate and 750 lines per second result in up to 7000 pts/m2 in 3m range at 80 km/h platform speed. Perfect scanner synchronization and high frequency operation result in a regular cross pattern of scan lines in unprecedented density. This feature enhances extraction capability and reliable detection even of minute details. The system enables the capture of the complete rail corridor, including catenary systems, rail heads, and the complete periphery, even signs orthogonal to running direction. Flexible camera options allow the complementation of scan data with high resolution imaging. Open interfaces to various external sensors enable to capture optionally additional data of interest during the scanning mission. Data export to Third-Party Rail-Processing software packages is provided.
