Penny Opto-recognition Software (POS) is my first excursion into optical image recognition. It is a software program which reads images from any Video4Linux-supported webcam and processes the image to discover the positions of several pennies within the field of view. A geometric representation of the recognized positions is displayed on the screen. Also recognized is a red translucent spoon which is used as a pointer to both digitally and physically manipulate the pennies.
The video is quite self-explanatory:
For the bandwidth-impaired, here are some photos of the system in action:

The pennyfix.c file is the one demonstrated here.
The camhacks.c file is an improvement of the peep-hole camera software. More on that in an upcoming post.

Very cool Navaburo…
I’m trying to think what this could be used for… perhaps a rudimentary ‘multi-touch’ interface of some sort…with pennies as the inputs… hehe…
keep up the good work!

Certainly,
I am often on irc, OFTC and/or Freenode using the handle “navaburo” (possibly with underscores). Try PM-ing me.
