matches_importer, terminate called after throwing an instance std::out_of _range

[weich37]

I use my own dataset to reconstruct a certain place, and the keypoints and correspoding descriptors are detected with my own method. However, when the code execute to "matching_importer", it throws errors as blow:
`I0423 07:01:30.535616 8257 misc.cc:198]

Custom feature matching

So, how can I fix this bug? Thank you
