Title: Anafi Parrot Drone- Wide vs Rectilinear lens
Post by: Mohammed on December 19, 2018, 03:33:46 PM

Dear Agisoft,

Next month i will work on a big site use Anafi parrot drone and i found that in the drone i can choose between Wide lens and Rectilinear lens, i read that rectilinear lens correct the images that yields images where straight features, such as the walls of buildings, appear with straight lines, as opposed to being curved.

So what is the best to use the default wide lens or rectilinear lens, i'm afraid that rectilinear will confuse the calibration inside the software?

Best,
Mohammed

Hello Mohammed,

If I have understood correctly the setting Wide lens/Rectilinear lens is used to toggle internal distortion compensation. If that's so, then it is recommended to disable such compensation.

Mohammend, I tried the Anafi right now and Im not happy with the results at moment.

I advice to set to JP+DNG non rectified and try to use the DNGs. My JPGs does not look very sharp, 90% of the images have a quality less then 0,8 calculated by Agisoft. So in my opinion, the imageset can not be used.

How is your experience with Anafi?
