Slanting section after AT - what is this? How do you fix?

Hi Brett,

I recently processed images shot with the Parrot Anafi drone. We flew four circular flights, like interlocking rings. The initial AT results had several slanted solutions mixed together like your screenshot.

I was able to get a good AT result by changing the AT Setting for Tangential Distortion to Adjust

Here's a screenshot of my AT using Keep for Tangential Distortion

(Notice the nice yellow interlocking rings of camera positions)

The final mesh production turned out great.

Does it have fisheye lens?

Hi Ron, 

I will give this a try. Thank you soo much for your idea on this. I'll let you know how it goes. 

Thanks, 

Brett

Oto,

I left the camera model type as Perspective. It has a wide angle lens. The EXIF info lists the focal length as 4 mm  (35 mm focal length = 23 mm).

Here's an example photo.

Looks "fishy" enough so try fisheye lens setting. I thing tangential distortion was setting before CC introduced fisheye lens support.

Ron,

What do you use for "sensor size" and "focal length" for your ANAFI photos? I'm using "undefined" and "4mm" which are the defaults and the meshes look good, but contextcapture displays the message "the sensor size of the camera 'Parrot/Anafi' is not in the database. Just wondering if these settings are correct. Thanks.
