reconstruction pipeline issues

[Prinsphield]

I have extracted features of R2D2, and was going to run the reconstruction_pipeline.py, but encountered the following error. Could you please take a look? I don't know why the number of triangulated points is 0 and the nothing was generated in the final_txt_model_path.

It seems that there are no matches in the database. Without matches it is impossible to build a 3D model.

[Prinsphield]

The db file is generated during the pipeline. What I have are all those extracted features. So may I know what's wrong with the process. I have no idea why there are no matches in the database. Another question is: in order to make a submission, do I need to run the all those steps in Localization?

[tsattler]

Can you give me some details on what you have done so far?

[tsattler]

Given that there has been no reply, I assume that this is not an issue anymore and am closing it.
