Trajectory Adjustment DJI Work Flow

[Rodrigo]

Hi friends, I'm working with the "Trajectory Adjustment" module of LiDAR360 because I need to correct a point cloud where the trajectory is misaligned, as shown in the following image:

The problem is that I'm trying to add flight trajectories obtained with DJI Terra, specifically the .SBET.OUT files located in the "lidars" output directory, as shown in the image.

I've tried manually adjusting the GPS time, but it's giving me the following error:

Does anyone know what might be causing this error and how to solve it? Also, what is the correct workflow for using DJI L1 with LiDAR360?

Thank you for bringing this to my attention.

Hello,

This could be a matter of Coordinate parameter, the .las data must be in the same projection than the sbet.out files.
For exemple, in France, I try to use " "Trajectory Adjustment"" with a .las projected in RGF93 and a sbet.out file which in WGS84 31N projection. > Doesn't work
Work with .las in WGS84 31N AND sbet.out in the same projection.

The survey date must be the date of the fly and not the date of the file processing by DJI Terra.
