Precompiled binaries for linux

[davn...@gmail.com]

Hello,

I would love to use your library for research purposes. Are you please planning to release precompiled binaries for 64 bit linux? It would help so much.

Thanks a lot!

David

Hi,

Compilation under Linux should be really easy. Please, refer to https://colmap.github.io/install.html#linux and let me know if you have any problems with those instructions!

Cheers,
Johannes

Hi Johannes,

thank you very much for the reply. After a day of compiling dependencies from scratch I managed to build the library and now I am playing with it.

First thing that doesn't work is the feature_extractor.

If I choose to use the GPU, I get the following error:

QXcbConnection: Could not connect to display

If I turn off the GPU everything runs fine.

Best,

David

Do you have a GPU in the system? If yes, which GPU and what driver version?

Thanks,

Hi Johannes,

thanks a lot for your help with colmap issues.

I managed to compile everything and I am currently happily executing colmap in large-scale problems on videos.

I have however encountered a problem that I am not sure how to solve:

I am currently reconstructing videos of cars which are all taken by the same camera (primesense carmine - basically the same as kinnect).

I thus fixed the camera intrinsic parameters inside the feature_extractor function to the parameters of kinect.

However, the code always crashes at the end of the bundle adjustment phase with the following error:

==============================================================================
Global bundle adjustment
==============================================================================
F1014 12:55:56.505967 81561 bundle_adjustment.cc:278] Check failed: solver_options.IsValid(&error) Can't use SPARSE_SCHUR as sparse_linear_algebra_library_type is NO_SPARSE.

Different camera settings dont cause the crash.

Can I please ask you whether you could help me with resolving this issue?

Best wishes,

David

Hi,

sorry for disturbing with the previous message. It seems that for bundle adjustment with unifocal setup, ceres has to be compiled with the sparse matrix support so it's solved now ..

Best,

David

[Johannes Schönberger]

Thanks David for your feedback. I will look into why this doesn't work for the single focal length case. 

Cheers,

Johannes

Hi,

I have been trying to install COLMAP on Ubuntu 16.04.2 LTS. I have all the dependencies installed without any problem. But when I try to compile COLMAP, I get the following error:

[ 81%] Linking CXX executable vocab_tree_retriever

make: *** [all] Error 2 

I have tried looking for similar issues on the internet, but haven't found any solutions yet. From the looks of it, the error originates from Boost libraries, specifically libicu55. But I already have that installed (installed boost version is 1.58).

Could you please point me on how to solve this problem and get COLMAP compiled on Linux? Thank you.

[Johannes Schönberger]

There seems to be some problem with how you installed boost. Did you resolve the issue in the meantime?

[jianan...@gmail.com]

Hello, David:

I was trying to compile COLMAP on windows and I encountered this problem too. 
 
you said, "ceres has to be compiled with the sparse matrix support".  could you please make it clear which sparse matrix support (the eigen sparse , the suite sparse or anything else ) you enabled ?

Best.
Jn.

Hi Jn,

I am not 100% sure what is the cmake variable for the sparse support as I did the compilation ~ 6 months ago. I was inspecting my Ceres cmakecache.txt file and it seems it might be EIGENSPARSE:BOOL=ON .

The CMakeCache.txt file is in the attachment in case you want to inspect it.

David

[Johannes Schönberger]

If you want SuiteSparse support under Windows, I recommend to use https://github.com/jlblancoc/suitesparse-metis-for-windows

Hi, David,

Thanks for your reply.

I have successfully compile with suitsparse and eigensparse and it works now.

Thanks again.

I did not manage to fix it on my local machine. I was using a Fedora system. But I had access to another Ubuntu machine, where it was setup properly and it worked.

[Johannes Schönberger]

Can you comment on which Fedora version? I would like to reproduce and fix this issue?

The Fedora version I was using was Fedora 25 Robotic spin, with the latest updates. I am not near my Linux machine, but will post back the detailed versions when I get back to it.

[morpheus...@gmail.com]

Update: I just checked my boost version installed on Fedora, it is version 1.60. Please let me know if you need any specific information for the system. All my other libraries are generally up-to-date from the official Fedora repositories.
