Driver to decode data from RIEGL VZ laser scanners.
All supported VZ scanners can operate in both long range and in short range mode.
In short range mode they can operate in 2D line scanning mode making them ideal for mobile scanning applications, where Qinsy will deliver geo-referenced point cloud co-ordinates, in real-time corrected for motion, heading and timing.
Laser stands for Light Amplification by Stimulated Emission of Radiation.
All RIEGL laser scanners are eye-safe (class 1R), except for the VZ-6000:
The VZ-6000 uses class 3B, which is not eye-safe, so extra precautions should be taken.
Characteristic of class 1R laser is that you will not receive any reflection from a water surface, which makes these VZ scanners ideal for combining with multibeam data acquisition surveys.
Note that class 3B is well suited for measuring long ranges in snowy and icy terrain.
It is highly recommended to interface the VZ scanner with a Time Synchronization pulse (aka PPS) in order to time-tag all data with UTC. Actually, this interfacing requirement is mandatory when using the scanner on a moving platform.
The pulse may come from an external GNSS receiver but VZ scanners have an internal GPS which makes interfacing the scanner to an external GNSS receiver obsolete.
In case you do not have a valid GNSS/GPS receiver (e.g. during testing or mobilization), or you use the scanner fixed on a tripod (so not on a moving platform), then you may select in your template setup the driver without "(With UTC)" in the driver name.
