Importing FBX & ABC Cameras not Working

[HaydenMartin]

I have a sequence of 900 images that need to be aligned, but I don’t have the time to run a Highest quality alignment on these images

To speed things up, I used an accurate camera tracking software to generate the 3D camera positions which are more temporally stable. I then export these cameras to FBX. They are named identically to their corresponding images.

Here’s the problem - when I export cameras from Metashape as FBX and re-import them, they work fine. But when I export cameras from my tracking software as FBX and re-import them to Metashape, they don’t build a point cloud and the Chunk gets labeled with “[T]”

I’ve tried everything and cannot figure out why a list of cameras in FBX from Metashape is somehow special. Is it something to do with the version of FBX? Binary vs ASCII? Maybe something to do with Keypoints being encoded?

I’ve also ran the same process using Alembic, running into the same issue. Sadly I can’t export as XML or Bundler .OUT from my tracking software… I’ve seen another user struggling with this here:

TLDR:
What is so special about Metashape’s FBX and ABC file format that I’m unable to replicate. I cannot seem to debug these file types as it seems they cannot be explored via text editors like Notepad

any pointers for this?

Hello HaydenMartin,

Please send to support@agisoft.com FBX and ABC files for import and the related Metashape project in PSZ format that contains only loaded images (without any processing applied).
