OpenMVG is a 3D reconstruction software focusing on automated techniques. This is used in AR and related technologies such as ARKit and Microsoft Hololens, and match-moving in video editing for inserting virtual content. It is also known as photogrammetry, structure from motion (SfM), 3D Computer Vision, and uses multiple view geometry heavily.

Building / Compiling m

Build Summary for Linux (24Oct19)

  • Install the required dependencies (see BUILD.md). Please edit this wiki page if you had to install more things.
  • Checkout OpenMVG, and make it lowecase
   git clone --recursive https://github.com/openMVG/openMVG.git    
  • Create a binary folder. I prefer the following setup: to have an openMVG-bin folder parallel to openmvg, outside the source
   mkdir openMVG-bin
   cd openMVG-bin
  • Configure and build
   cmake -DCMAKE_BUILD_TYPE=RELEASE ../openMVG/src/
   cmake --build . --target install

Build for development with GCC and interactively

   CC=gcc-5 CXX=g++-5  ccmake../openMVG/src/


Build Summary for Mac (24Oct19)

  • can try '--fast-math' optimization, gcc-5 is very good at that.
  • I use BUILD_SHARED_LIBS on. Faster linking. Faster development cycle

OpenMVG as a library

  • Careful: If you want to use OpenMVG as a library, you must define your prefix, and not only
    make
    but also
    make install
    • What I do in this case is cd openMVG-bin, then 'ccmake -DCMAKE_INSTALL_PREFIX:STRING=$PWD/install ../openMVG/src"


Same as Linux currently works.
