How Necessary is Parrot Sequoia Calibration?

How necessary is taking calibration images when using the Parrot Sequoia?  If it provides a big benefit, where do I get calibration targets to take the images of?


Would this target I have for another camera work?



Calibration targets provide the absolute value for reflectance which can be compared to maps from any cameras. If you are not using a target you will get a relative value which can be compared to maps generated from the same camera.

Parrot sequoia+ does not need targets as they are factory calibrated.

I looked at your target. For targets to be used you will need to know the reflectance factor of each surface of your target (it looks like there are 4 materials) and you will be able to use only one surface.

Let me know if it is not clear. Thanks :slight_smile:
