I am using Parrot Sequoia (Firmware v1.2.1). for computing NDVI. I am trying to understand the process through which the final images are acquired from the sensor. Specifically, I want to know whether Sequoia compensates for Vignettingand Dark Current effects inside the firmware or do these corrections have to be applied manually in the software?
If they have to be corrected manually, then:
- How can we utilize the captured images’ EXIF information to correct vignetting?
- Does the exif tag BlackCurrent correspond to the dark current suppression? How can we use it to correct the dark current effect?
