Research direction
Start with the bin/opensfm extend_reconstruction entry point and its command help, then trace how reconstruction.json and the images folder are consumed. No source file or test is named; done would require a verified usage example or clarified documentation explaining the expected inputs and output.

Description
Hey y'all, I've seen this discussed before but I haven't been able to get an answer for my problem. In the NodeODM container I call
bin/opensfm extend_reconstruction /var/www/data/251ce1df-643a-412f-a4e9-13d2c41f71bd/opensfm --input reconstruction.json --output reconstruction2.json
This does create reconstruction2.json, but this output tells me something is definitely wrong:
2024-08-05 00:23:41,750 DEBUG: Ceres Solver Report: Iterations: 39, Initial cost: 2.042603e+04, Final cost: 1.586630e+04, Termination: CONVERGENCE

2024-08-05 00:23:43,119 INFO: Removed outliers: 90
My process is as so:
- Add ~10 images to the images folder under the project
- Run command specifying the dataset to be the opensfm folder under the project
- Same output as shown above, for any number of images added (even with none)
I'm quite sure I am invoking the command incorrectly, so could anybody provide an example or explain what part I'm doing wrong? Thanks!
