Hello guys, I'm in need of advices.

Recently my company just purchase DJI L1 sensor for a vertical stucture surveying (dam). As I made a site visit, I noticed that I required to fly manually for the lidar. I've stumbled upon few threads with regards L1 vertical surveying & IMU calibration. So by any chance, I'm looking for wisdoms/tips from you guys in term of lidar manual flying workflow and general parameters.

Thanks.

Hi! You might be better off posting your question in the 'products' section of this forum.  That is way more active.    -   https://forum.dji.com/forum-129-1.html

Hi,
Facade scanning is currently not implemented in Pilot 2. You can do it manually or use UGCS as an alternative.

I try to flight manual but confuse about before and after IMU calibration. thus we get DjiTerra error code 8005

Would you mind if you give me flight  manual  work flow step by step

Which is correct workflow for flying manually

A: 1. Start record 2 Calibartion IMU 3. Capture LiDAR 4 Calibration IMU 4 Stop record 5 UAV landing

B: 1. Calibration IMU 2 Start record 3. Capture  LiDAR 4 Stop record 5 Calibration IMU 5 UAV landing

C: 1. Calibration IMU 2 Start record 3. Capture LiDAR 4 Calibration IMU 5 stop record  6 UAV landing

1/ RTK fix (or PPK base station ready) + IMU warmup done
2/ take off
3/ Fly random pattern with directions change at max speed
4/ IMU calibration
5/ start Lidar record
6/ stop record and perform IMU calibration after each 100s
7/ restart lidar record and continue
8/ at end stop lidar record
9/ perform IMU calibration
10/ land

In every case the base station must be at maximum 20-25km. Flying between building will disturb the GNSS signal.

Let me try, many thanks.
