Command line Geotagging

Hello all,

I am looking to find a geotagging program that has the same functionality as the geotagging tool built into Mission Planner. The purpose is to be able to take a flight log (.BIN or .log) and the set of imagery tied to that flight and geotag the entire set using only command line processes. This is to allow automated and hands-off geotagging without having to spend extraneous time monitoring the geotagging in Mission Planner.
Does anyone have an idea if a program like this exists or where I should start with in creating one?
Thanks
