Question about how to generate the mesh about aachen? #2

Closed Gatsby23 closed 1 year ago

tsattler commented 1 year ago

Please have a look at the paper corresponding to this repository (https://arxiv.org/pdf/2207.10762.pdf). The meshes are available here: https://data.ciirc.cvut.cz/public/projects/2022MeshLoc/aachen_day_night_v11/meshes/

Sorry for bothering you again: when I run the undistort the images. It shows boost::filesystem_error:

It shows No such file or directory: "~/Dataset/dense/images/sequences/nexus4_sequences/sequence_1"。

Have you met the same Problem？What version of colmap have you used?

tsattler commented 1 year ago

Any recent version of Colmap should work. I either used 3.6 or 3.7.

Are you sure you have downloaded all necessary images for the Aachen dataset?

Yes, by the way, what is the memory about your computer？

tsattler commented 1 year ago

I used a PC with 64 GB RAM to create the models.

When I use the colmap GUI to do the stereo fusion to get the ply. It always get killed. Have you met this problem?

tsattler commented 1 year ago

You are likely running out of memory. There are some tips on how to handle limited resources in the Colmap documentation and the Colmap faq.

Yes I have noticed that, have you downscale the image size to do the reconstruction？ My computer is 128 memory. But it still met the problem.

tsattler commented 1 year ago

I think I have created multiple meshes, both at lower resolution and at a maximum side length of 1600. For the fusion step, I typically limit the amount of memory Colmap can use.

Sorry for bothering you again. I'm a freshman to the colmap. How to limit the colmap use at all？ The only thing I can find is to downscale the cache( from the tip at here: https://github.com/colmap/colmap/issues/732). I don't want to downscale the image resolution at all. Could you please give me some tips about that？

tsattler commented 1 year ago

Yes, I meant reducing the cache size.

Gatsby23 commented 1 year ago

I download to the 16 cache, but it crashes at last. Could you please share your cache size？

tsattler commented 1 year ago

I think cache sizes of 16, 24, and 32 GB have worked for me. I don't think I used a smaller cache size for the Aachen model (but it is also some time ago and I don't remember).

I use the 16, but the memory size is still increasing until it's crashed.
