Compiling OpenMVS

[Brian Loudon]

Hi, I was wondering if you could give me some advice on first time compiling. I'm not great at custom usage of cmake-gui and I am really tearing my hair out trying to get Ceres to compile in order to then use it with OpenMVS.

I have failed to build Ceres 1.11.0 from the source download, mainly as I can't get Glog to compile and be included in cmake.

 so... I have had to use the windows wrapper I found here;
https://github.com/tbennun/ceres-windows

with ceres 1.10. which I managed to compile fine. Though that windows wrapper does not seem to contain any cmakelist files...

I am trying to then run cmake-gui on the OpenMVS files and again I have  GLOG_INCLUDE_DIR problems;

CMake Error at D:/OpenMVS/ceres-windows-master/ceres-solver/build/CeresConfig.cmake:85 (MESSAGE):
Failed to find Ceres - Missing required Ceres dependency: Glog, please set
GLOG_INCLUDE_DIR.
Call Stack (most recent call first):
D:/OpenMVS/ceres-windows-master/ceres-solver/build/CeresConfig.cmake:188 (CERES_REPORT_NOT_FOUND)
build/Modules/FindCERES.cmake:31 (include)
libs/MVS/CMakeLists.txt:15 (FIND_PACKAGE)

I am really out of ideas at this point as I have entered the GLOG_INCLUDE_DIR and I can't see what can be wrong,

any hints or suggestions would be gratefully received, getting a bit hopeless here,

Really keen to try out the capabilities of OpenMVS

Many thanks,

Brian

Hi Brian,

In order to compile CERES, you only need Eigen (the other dependencies are optional). Do not use any wrapper, just download CERES source-code, run cmake and configure it to not build tests and examples, and select miniglog (replacement for GLog, already included in CERES). Build and install, and that's it.

Hope this helps!

[Brian Loudon]

thanks so much for replying! Much appreciated, it's been a frustrating day,

The problem I get when compiling with miniglog is;

CMake Error at D:/OpenMVS/ceres-solver-1.11.0/bld/CeresConfig.cmake:88 (message):
Failed to find Ceres - Ceres include directory:
D:/OpenMVS/ceres-solver-1.11.0/include does not include miniglog, but Ceres

When trying to configure OpenMVS with;

CERES_DIR     D:/OpenMVS/ceres-solver-1.11.0/bld

CERES_INCLUDE_DIR     D:/OpenMVS/ceres-solver-1.11.0/include/ceres

Many thanks again,

Brian

[cDc]

I do not know why it is not working for you. Please try copy by hand the miniglog header and put it so that cmake finds it.

Thanks, I've tried that, and now I've tried it with Ceres1.10  I really can't think of any other permutation of this. It's so frustrating as it's just this silly wee header file that is blocking everything! Think I have to give in for today.

success!

moved miniglog folder copy to D:\OpenMVS\ceres_solver-1.10\include\ceres\internal

was under    D:\OpenMVS\ceres_solver-1.10\include\internal\ceres

I have generated the solution file without OpenMVG support for the moment as something odd happened with the cmake files there too, so I'll keep that build completely separated for the moment.

Unfortunately the solution did not compile, a lot of errors mainly in ..\libs\common\types.inl  ,  ..\libs\common\util.inl and cuda.h    I am compiling in MSVC 2010 as an x64 build, should I compile it as win32?

Can I ask is it possible to set OPTDENSE::fOptimAngle  from the config file or "dense-config-file"  , I'm just trying out some data with the OpenMVS_Sample package I downloaded. Got some great results on one openmvg scene, just trying something else. From looking at the code fOptimAngle defaults to 12 degrees, is this correct? Can it be changed?

Thanks again!

cheers,

Brian

Hmm, it should compile on both x64 and x32, and also on VC2010+, but I never test it. I use VS2015 x64 (that means with C++11 support). So some of the non C++11 code must give you problems. You either try to fix it (or wait for a fix from me when I will find time), or use VC2015. Sorry for that, but I work on this project only in my free time, so most of the time I spend earning my money on different projects.

[cDc]

I forgot to answer your second question. In order to set OPTDENSE::fOptimAngle (or any variable in OPTDENSE) you only have to enable the configuration file using "--dense-config-file Dense.ini". If it doesn't exist it will be created, if it exists, it loads the parameters that it contains.

That's great thanks, just trying that now to experiment with settings, looking to see what angle between views I can get away with.

I have tried again to compile with MSVC 2015 Community and have compiled libraries Common, IO and Math (.lib) , however MVS.lib throws an error on compile when it tries to link into the CGAL libraries, autolink.h (in CGAL dependency) can't find the CGAL libraries. I compiled those as dlls, should they be static libs? I think there may be something odd with my Boost install for this to happen.

Sorry, that's my last question.. Apologies again for such low-level compiling questions.

many thanks,

Brian

[cDc]

No problem at all, I'm here to help. However, I can not say what the problem is from the distance. I didn't encounter this problem in my attempt to compile the library, but it sounds like something went wrong at creating the projects. Most probably an include folder that is needed it was not included for some reason. So the simplest solution just added it by hand.

[Brian Loudon]

Just wanted to say thanks, I managed to compile the solution finally!

I still suspect something isn't quite right as DensifyPointCloud failed on my data that worked wth your OpenMVS_Sample package (the model of a Venetian statue I posted in another thread) I think there's something odd with my opencv 3.0 install potentially. It gave me this error message:



Still, this aside I can now experiment with the toolkit and learn from it.

Thanks for the amazing work, I will try to post some images of the reconstructions I process.

cheers,

Brian

[cDc]

indeed, strange error. But glad you managed to compile it! Good luck with you next experiments, looking forward to see some nice results!

[cDc]

So on my machine I chose to compile everything with static links. Anything should work as long as you are consistent: you either compile with static or dynamic libraries, but everything the same.

The problem with JPG files not opening is also because you have a conflict of libraries. Im quite sure you are using one version of jpeg library for OpenMVS and an other version comes with OpenCV.

Hi I'm afraid I had a bit of a false dawn... The exe file couldn't open jpeg files - quite essential - and I'm back in linker hell.

Can I just ask do you compile using static boost libraries for CGAL? and do you make static libraries for CGAL and OpenMVS?

I have been trying to compile without shared libs to make it entirely static, compiling everything with /MT or /MTd

many thanks,

Brian

As far as I know BOOST doesn't link to zlib automatically on windows, you have to set the path to zlib manually.

Here is the script I am using for compiling BOOST.

PS: in the future please reply here, as this discussion could help others as well.

Thanks, I've been compiling with shared libs, so I guess I'm going down a slightly different route here. Everything is fine up until I compile the apps and I get linking errors concerning boost iostreams;

Error    LNK2001    unresolved external symbol "int const boost::iostreams::zlib::best_speed" (?best_speed@zlib@iostreams@boost@@3HB)    DensifyPointCloud    D:\OpenMVS\2015build\apps\DensifyPointCloud\MVS.lib(DepthMap.obj)    1

I found comments on the internet about zlib not being built by default into dynamic boost libs, so I compiled it with boost.build against the zlib sources I have in opencv3. Unfortunately I have the same errors.

Doubting whether I managed to compile iostreams correctly I then looked again at the pre-compiled boost package and they state there that "Starting with 1.49, the zlib and bzip2 libraries have been built in for use with the iostreams library." so that shouldn't be the issue.

boost.teeks99.com

any ideas?

cheers,

Brian

[Brian Loudon]

Thanks for that! Working through that and compiling zlib and boost has worked and I now have a compiled DensifyPointCloud.exe (just doing one first to start)

On running it however I once again have the jpeg error that I had the last time I compiled successfully.

I've noticed that when I compile IO.lib, I get these warnings;

1>  Generating Code...
1>ImageTIFF.obj : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library
1>ImagePNG.obj : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library

1>  IO.vcxproj -> D:\OpenMVS\2015build\bin\vc14\x64\Debug\IO.lib

Is this why it can't load a jpeg?

Many thanks, I nearly cried when that compiled there!

As I said in the previous replies, OpenCV and OpenMVS both use and link to jpg, png, etc. Your error is generated cause you probably are linking OpenCV statically and the jpg version used by OpenCV is different than the version used by OpenMVS. Make sure you use same version.

[Brian Loudon]

embarrassingly enough, I think I actually had no link at all to jpeglib in IO.lib. I think in cmake-gui I hadn't entered anything for jpeglib and it was not defined, I commented out the #ifdef and got ImageJPG.h included.

DensifyPointCloud now runs up until it does the neighbour selection;

    ASSERT(pointsA.GetSize() == pointsB.GetSize() && pointsA.GetSize() <= score.points);
        const float areaA(ComputeCoveredArea<float, 2, 16, false>((const float*)pointsA.Begin(), pointsA.GetSize(), boundsA.ptr()));
        const float areaB(ComputeCoveredArea<float, 2, 16, false>((const float*)pointsB.Begin(), pointsB.GetSize(), boundsB.ptr()));
        const float area(MINF(areaA, areaB));

calls ComputeCoveredArea()

fails on this assert;

inline TYPE ComputeCoveredArea(const TYPE* values, size_t size, const TYPE* bound, int stride=n) {
    ASSERT(size > 0);

Whilst processing the 10th image out of 13 on the dataset I had run previously with your pre-compiled code.

cheers,

Brian
