Bobby is the main developer for OpenAthenaIOS btw.
@rdkdji I don't think email is public on profile
Regardless, we can accept images in emails to [email protected]
Not sure, what exact error message does it give?
If it says something like 'missing EXIF data' then it's probably something with how the photos were copied rather than how they were taken from the drone
Also the Mavic 2 Zoom has some of the best accuracy of any of the models we've tested so far. I'm also eager to do testing with the Mavic 3 given its nice telephoto zoom camera
EXIF metadata is basically just hidden tags and values automatically included in images taken by a camera. It doesn't need Internet access to record these tags when an image is taken. Usually it includes stuff like exposure time, camera settings, focal length, etc. For drones, it often includes...
Notation for sensor size is a whole big can of worms. Basically, the published numbers are usually just a marketing gimmick based on decades old notation called 'optical format' owing back to when camera sensors were based on vacuum tubes:

We'll take another look at DNG photos I believe last time we evaluated them they had the same EXIF metadata but didn't have the XMP metadata for stuff like camera angle, but it's certainly worth another look.
That's great feedback on possible usability improvements.A Mac version with easier...
Hi y'all,
We just released update v2.5 of our OpenAthena app for iPhones and iPads. This update simplifies and expedites drone use for critical tasks such as Search and Rescue, precision agriculture, law enforcement, and land management.
Unlike other methods that require many photos and lots...
Hi @DJ Wes,
We maintain a list of most DJI camera parameters (including sensor size) for our OpenAthena software. This data allows for angle calculation from any pixel for our software's terrain-raycast:
The full list is below. We try to keep it updated as new models come out, but definitely...
Not at all!
Good questions, as they are foundational to the functioning of the software.
The app introduces a new technique for sensor fusion of drone images (and their included metadata) with a Digital Elevation Model of terrain. A significant benefit to this approach is it can work instantly...
Hi,
It's a great weekend to get out and fly, so accordingly we've released some more free updates for you all for OpenAthena. The app allows you to locate anything within any single drone image, turning what's usually a complex mapping task into a simple, quick action:
Our latest update for...
We've released v0.19.5 for the Android version of this app, improving accuracy for the Mavic 2 Zoom and Mini 3 Pro drone models:
https://github.com/Theta-Limited/OpenAthenaAndroid/releases/tag/v0.19.5
(also available in Google Play)
We are still in the process of improving the Android app to...
Just verified the DJI Mini 3 is also incompatible, even though the Mini 3 Pro is.
Photos from the Mini 2 and Mini 3 are missing important metadata for the aim of the camera. This appears to be intentional on the part of DJI:
The updated values for the Mini 3 Pro in our cameras database were generated by our manual camera calibration process, described in full here:
https://github.com/Theta-Limited/camera-calibration
A new value for the Mavic 3 Pro's 1/1.3-in. Medium Telephoto Camera (EXIF model FC4382) was...
We've released an update v2.01 adding:
- general UI improvements
- accuracy enhancements for the DJI Mini 3 Pro and Mavic 3 Pro
It's available on the App Store now:
