Memory Cards
| Note |
|---|
Only new SD cards may be used (depending on the number of recordings, ~0.5years to 1 year max). With older SD cards it is possible that errors occur in the IR videos and that the corresponding flights have to be repeated. |
| Note |
|---|
Only use the memory cards mentioned here (see DJI M3T specs):
Using a different memory card will result in corrupted videos and it will not be possible for Volateq to evaluate the data. |
DJI Pilot App: basic settings and pre-flight check
Start by turning on the drone and the controller.
Open the DJI App and log into your DJI user account
make sure you have access to the flight hub account and your plant/project
Never change a running system: Firmware updates Yes, but not directly before the flights (updates make take very long)
Enter Camera view
...
| Note |
|---|
If there is a version update, do not update it directly before a data acquisition flight. In that case reject the update and choose “later”. After finishing the flights for the data acquisition, install updates and do some test-flights. |
Switch between different https://fh.dji.com projects:
make sure to be logged in to the right account
switch between plants/projects (usually there is only one)
...
Pre-flight check:
check flight mode and battery
check storage (recommended to format SD card before an new analysis)
Max flight distance (depends on size of the solar field)
Max Altitude (150 - 180 m (depends on legislation limits, elevation model of the plant and start position of the drone)
Obstacle avoidance (usually ON!)
...
To enter the camera view, just close the pre-flight check with the cross in the upper right corner
...
The simplest solution is to protect both wheels on the front of the controller with tape, to avoid accidentally touching the wheels and altering gimbal tilt and/or zoom:
Visual Camera view
switch between video streams (attention: the actual stream is marked in the green box at the top center)
After each re-boot or battery swap camera settings are lost. you always have to set the EV (exposure correction) to -1.7 for both visual video streams (Wide & Zoom)
make sure all three video steams are active and there is sufficient storage
Do not use
Auto exposure
AE lock: Never activate!
Auto camera → never switch to manual (will corrupt exposure settings)!
Link (this will completely corrupt videos)!
...
activate all three available video streams:
...
Video caption always ON (stores GPS and altitude information in a separate file, that is used to match videos and digital twin)
Time stamp always OFF
...
Infrared Camera view
Gain mode must be
low (0°C- 500°C) for CSP inspection
high (-20°C- 150°C) for PV inspection
SBS OFF
Link OFF (this will completely corrupt videos)
...
Video caption always ON (stores GPS and altitude information in a separate file, that is used to match videos and digital twin)
Time stamp always OFF
...
IR Scene mode: INSPECTION
Auto FFC: ON
...
Infrared “Super - Resolution“ : OFF
Sun Burn Protection: OFF
| Note |
|---|
The sunburn protection has to be disabled BEFORE EACH FLIGHT, because it reactivates as soon as the drone is restarted. |
