We're doing a trial run for a project that involves plant health. We want to capture fields with two weeks in between to see what the difference is. So we took our DJI Phantom 4 Pro for a test flight over a field and repeated the same flight (copy of planned flight within the DroneDeploy app) twice.
The camera exposure settings were set to manual and I changed these for both flights due to lighting changes.
Now: The processed results with the option "Plant health" are severely different. But there was only 10min in between those two flights. In our opinion the results for both flights should be the same, regardless of the exposure settings. In two weeks from now the light will be completely different anyway, so we're not sure what we'll be comparing.
What would be the best approach for this issue? And is the Phantom 4 Pro the right tool to obtain information about plant health?
Any help is highly appreciated.
