I put together a fun script which isolates colors using HSV filtering and then finds the largest “blob”, which is presumably an object that should be tracked. It then finds the center of the “blob” draws a target indicator on it, along with the X,Y coordinates.

The result is surprising good object tracking with minimal code. I have yet to port it over to the BeagleBoard because I wrote the script taking advantage of OpenCV’s “CV2″ library which requires Python 2.7. Unfortunately Only 2.6 is available via packages for the BeagleBoard and I have had little success in getting 2.7 to cross-compile. So I’m in the middle of porting the code to use only the core “CV” functions.

Here is the results of the object tracking (running on my Windows laptop):
