Ground reference evaluation
NOTE
When the ground reference evaluation function is activated, the mean filter is automati‐
cally deactivated.
The ground reference evaluation function enables the LiDAR sensor to protect hazard‐
ous areas when used in conjunction with automated guided vehicle systems (AGVS).
Any objects lying on the path (pallets or small load carriers), or steps and depressions
in the ground, are distinguished and detected, thereby avoiding collisions.
The PC software SOPAS ET is used to configure the device and enter the installation
location (position of the device),
"Operation with SOPAS ET", page 43

application parameters must be taken into consideration and adhered to:
