Is there a way to get the warping transforms for each image?

Feedback Ideas and Proposals

I am new here, sorry if this is in the documentation somewhere. I want to map back from the orhtomosaic to the original images. Is that information available? The best would be a mapping of original pixel -> geo coordinates, but whatever OpenDroneMap provides would be great.

I have an application in mind that would do some object detection on the original images and then map that to their location in the world, but creating an orthomosaic with the original resolution is too large, and my detection fails when I use a lower resolution.

Yes, check odm_report/shots.geojson and opensfm/reconstruction.json.

Cool, thanks.

If I may ask, how would I use the rotation to create a ray, specifically using the drone_dataset_brighton_beach data, I get a shot.geojson like this, what would be the easiest way to get the coordinates at height 0 in the translation coordinate system?
