Wonder how to start with OpenMVG:

• Wiki
• Online doc
• 3D reconstruction Bibliography Please help to keep it up to date
• Dataset

Hi Everyone,

I am trying to implement incrementalSFM on 20 images, with EXIF metadata [Latitude, Longitude]. I know the next step is matching, but want to go with LOW ratio match on 20 images and then rest of 19.

I was wondering if there was a way to intelligently determine the probable match by using the exif data or any other method .
Or
how OpenMVG Solve this Problem ??

Thank you in advance

Note that we have a matching that use pair coming form GPS neighborhood position
See here https://github.com/openMVG/Image_datasets/tree/main/Drone#using-gps-prior-for-pair-selection-and-sfm-prior-optimize-in-gps-xyz-coordinates
You even have a dataset to play with ;-)

Hi everyone!

I'm trying to build up the OpenMVG on my Windows computer. I followed the instructions as "build.md" says, but after I cloned the code and configured in CMake, I found there are a lot values are NOTFOUND.

e.g.
CLPSOLVER_LIBRARY-NOTFOUND,
CLP_LIBRARY-NOTFOUND,
Ceres_DIR-NOTFOUND,
Eigen3_DIR-NOTFOUND,
GHOSTSCRIPT_EXECUTABLE-NOTFOUND

Is it means I still need to download extra packages? Or what can I do to fix this problem?

Best regards

Did you checkout with recursive or have initialized the submodule?

I rarely use the cake gui interface so seeing some value empty or not found could maybe normal
