I'm trying to create a 3d model of a site in Australia. After running the AT i get a bunch of photos that just go off on a different plane and a corresponding section of points that run off with them. Has anyone seen this before? Does anyone know that the fix is?
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
Here's a screenshot of my AT using Adjust for Tangential Distortion(Notice the nice yellow interlocking rings of camera positions)
The final mesh production turned out great.
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.
I used 5.98528mm for the sensor size (width) and 4mm for the focal length.
These are the specs I found online for the Parrot Anafi camera sensor. (I added the red and blue comments)
