How to down NordLand test dataset #53

Closed HeartbreakSurvivor closed 2 years ago

HeartbreakSurvivor commented 2 years ago

Hi, I really appreciate for the work you've done. I want to test PatchNetvlad on NordLand dataset , so I download NordLand dataset from here, but the dataset seems not the the same as your provided nordland_imageNames_query.txt, nordland_imageNames_index.txt . besides, the datasets I have downloaded do not provide ground truth file, so could you please tell me how can I get NordLand test dataset?

Hi,

You can download the full dataset from here: https://nrkbeta.no/2013/01/15/nordlandsbanen-minute-by-minute-season-by-season/

You can then extract 1 frame per second using e.g. ffmpeg (see https://nikosuenderhauf.github.io/assets/papers/openseqslam.pdf). The videos are pre-synchronised, such that frame X in one traverse is the same place as frame X in any of the other traverses.
