Hi,

I am working on processing a project of roughly 12,000 photos of a nature reserve with my Phantom 4 Drone and MicaSense. There are clear flight lines, but on most of the images there is a warning that there is “no path from reference to camera #.” I am also getting an error message that says “[BundleAdjuster][minimize] no projections errors ! aborting.” Would anyone have any suggestions about how I could fix this?

Hi, welcome to the Pix4D Community,

`[Error]: [BundleAdjuster][minimize] no projections errors! aborting.`

This might happen if there is not enough overlap or the image quality is not good. Can you give us a screenshot of your flight plan (mapview in PIX4Dmapper)? What was the frontal and side overlap? What was the flight height?

cheers
