Feature Request: Face and License Plate detection / Recognition

[whopperg]

Hi there,

i've tried my way with openbr/vc but i cant get it to work. So i took a look at the web and saw that there actually is a plugin for zm! (http://www.zoneminder.com/wiki/index.php/Third_Party_Patches)

Is this also included in this branch? If so, is there an Tutorial?

Cheers,

The guy who was developing that stuff has been away for a while. So it hasn't been merged. He mentioned that he might be back soon, in which case maybe it will get merged. My cluster ppa has his plugin framework in it, but no plugins.

Feel free to take up the torch...

I have done some work on this. In fact I have a local branch with the plugin framework finished (the unixmedia code does not implement full plugin support in the web interface). And I have tested the face detection and LPR plugins but none of them can be used (by far too much false positives). But I am currently testing a LPR plugin based on openalpr library (https://github.com/openalpr/openalpr) and I have good results.

[manupap1]

I will send a pull request for plugin support before the end of this year (now I am focused on debian packaging). That will be my christmas gift. But beware this will include some deep modifications in makefiles (necessary to support shared libraries). The basic idea is to provide a plugin development library.

Sounds awesome! Thanks!

[manupap1]

Sorry I have not been able to focus on this subject during the past weeks. I just refreshed my fork of ZoneMinder with the plugin framework: https://github.com/manupap1/ZoneMinder (plugin_support branch) I am not sending a pull request right now because this stuff depends on https://github.com/ZoneMinder/ZoneMinder/pull/646. The LPR plugin is there: https://github.com/manupap1/libzoneminder-plugin-openalpr If you want to test, please follow instructions on the README.md file.

[connortechnology]

I'll get onto testing/merging #646 soon.

@manupap1:

Nice work mate! Loved the documentation! Just cloned your fork and try to install it as i write.

Cheers!

[whopperg]

well - i failed. or at least the build:

Here the last output:

make[1]: Entering directory '/downloads/manuapap1/ZoneMinder' I: zoneminder_1.28.1 dh_install --fail-missing cp: cannot stat âdebian/tmp/usr/share/perl5/ZoneMinderâ: No such file or directory dh_install: cp -a debian/tmp/usr/share/perl5/ZoneMinder debian/libzoneminder-perl//usr/share/perl5/ returned exit code 1 debian/rules:80: recipe for target 'override_dh_install' failed make[1]: * [override_dh_install] Error 2 make[1]: Leaving directory '/downloads/manuapap1/ZoneMinder' debian/rules:46: recipe for target 'binary' failed make: * [binary] Error 2 dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2 debuild: fatal error at line 1376: dpkg-buildpackage -rfakeroot -D -us -uc failed

[manupap1]

@whopperg This should be fixed now.

[whopperg]

Thanks mate! Its working - after some smaller hickups :-) Going to build the plugin now. I'll get back to you with more Infos if you want to.

Cheers!

[whopperg]

Got another one ;-)

[manupap1]

It failed because you have a local installation of the libopencv_imgproc library which takes precedence over the package version of the library. And obviously dpkg-shlibdeps does not find a package dependency for this local library.

Run the following command should point out the problem:

ldconfig -p | grep libopencv_imgproc.so.2.4

Your options:

• If not in use, remove the local library and retry to build the package,
• Change the path priority in ldconfig and retry to build the package,
• Do not build the package, and simply install with sudo make install.

Thanks manupap1 :+1: (i've really tried all i could but building packages and stuff but this isnt really my thing ;-) mostly im a Windows guy : ) sudo make install did the trick. Plugin is running! I have to wait till my wive is back home to see if it catches the plate ;-)

[manupap1]

@whopperg If you have some issues about the plugin, thanks to report them on my repository.

[whopperg]

@manupap1: Thank you very much. I will do that.

Should i keep this request open for face recognition part?

[manupap1]

I would say to keep this request opened for now.

Closing this out since it appears that @manupap1 has written a ZoneMinder plugin that does this. https://github.com/manupap1/libzoneminder-plugin-openalpr
