How to calibrate autonomous forklift LiDAR in multi-level mezzanine setups?

We recently deployed three autonomous Raymond reach-truck systems equipped with SICK microScan3 LiDAR arrays inside a multi-level steel mezzanine facility. The problem is that when the forklifts transition from the concrete ground slabs onto the steel-plate mezzanine platforms, structural floor vibration throws off the elevation reference by about 12-18mm. This is causing safety-stop false triggers at the dock door transitions.

Is anyone running adaptive thresholding on their LIDAR arrays, or are you physically decoupling the mount assemblies to damp out the high frequency vibration?

  "safety_field": {
    "detection_range_mm": 1800,
    "tolerance_offset_z": 12,
    "structural_filter": "high_rigidity"
  }
}

Excellent advice from Helmut there. Note that if you change the integration window parameters to 90ms, you must recalculate your safe stopping distances under standard regulatory guidelines (e.g., ISO 13849-1). Since the vehicle response time will increase by 60ms, ensure that your braking zone safety envelopes are scaled outwards by approximately 8-12cm depending on max travel velocity.
