alignment.JPGHello fortum

New DJI Zenmuse L2 and Lidar360 user here. Could someone guide me how to "lift" the two strips 0.08m shown in the center of the attached image using Lidar360? I tried Calibration tool, but it didn't do anything. Can I somehow select the two pointclouds and increase the Z-value for all points by 8cm?

Cheers!

Use "Preprocessing/Transformations/Manual Rotation and Translation" for "increase the Z-value for all points by 8cm  ".
But this does not always help, since the trajectory often has a variable error, a meter at the beginning and two meters at the end.
Another way is by checkpoints, if there are any.

Hi Konstantin. Thanks for helping out!  As far as I see, the trajectory error is constant for two strips and I suspect it was caused by a momentary loss of the RTK signal suring the mission.

I cannot find "Manual Rotation and Translation" under the Preprocessing/Transformations/ -menu. I'm using Lidar360 v7.2. Could it be under some other header?

I have version 5.4, perhaps this section has moved somewhere?
