Error data and correlation similar to Metashape matrix #1025

Closed lupionpe closed 4 months ago

lupionpe commented 8 months ago

Hello guys, I am new here.

I used to use Agisoft Metashape in my projects, and on their report there is the camera parameters and the error and correlation between them.

I was looking for a way to have something similar using OpenSfM.

I have done some investigation here and also try to find the in the files, such as reconstruction.json and reconstruction.nvm if I could get this information, or recalculate it, but I did not have success.

Are there any files, logs, etc where I could either find or recalculate those numbers?

Cheers Lupion cc: @felupion

Hi @lupionpe, have you looked at the reports and statistics? A lot of information about (re)projection-errors are only available at runtime, but not saved to the final reconstruction-files. The stats for example are generated from the reconstruction objects here. Maybe you can use this as a starter?

The final camera-parameters should by available from the reconstruction.json if I recall correctly.
