Sync Angle 0~360 degrees
By default, the LiDAR's 0° position (see
Section 1.2) is not in sync with GPS PPS or
the whole second of the PTP clock.
If syncing is needed, check the checkbox
and input a sync angle.
Trigger Method Angle-Based / Time-Based
Angle-based: lasers fire every 0.1° at 10
Hz or 0.2° at 20 Hz.
Time-based: lasers fire every 27.78 us.
Noise Filtering Mitigation of noise points
Interstitial
Points Filtering Interstitial point: when a beam partially
hits on a front target's edge and further
hits on a rear target, the return signal can
result in a false point located between
both targets. Such points can be
mitigated.
Retro Multi-
Reflection
Filtering To mitigate the false positive points at
twice the distance of a retroflector.
Up-Close
Blockage
Detection When OFF, the Distance field in Point
Cloud Data Packets only outputs distance
measurements that are over 0.3 m.
When ON, see Section 3.1.2 (Point Cloud
UDP Data).
