Hi all,

I would like to use the openfab place recognition module in a commercial project, but the original source code http://code.google.com/p/openfabmap/ is released under GPL, whilst OpenCV is under BSD. So what is the license of the opencv fabpmap module?

Thanks in advance

The project explicitly says it is released under GNU GPL v3. So you're a bit out of luck if you want to use it for a commercial project.

There is one circumstance I know where you can mix GNU GPL with a commercial product. If your commercial program calls a GPL executable eg. via system("gpl.exe");, then this is OK (at least back with the original GPL).
