I finally finished my port of the E1 object tracking from OpenCV (CV2) / Python 2.7 to OpenCV / Python 2.6. I had to do this because Beagleboard doesn’t have a readily available Python 2.7 package (at least not with Angstrom), and I didn’t realize that OpenCV (CV2) required Python 2.7 until after I developed the original code on my laptop.

This was a bit of pain because there are not many examples. If your platform supports Python 2.7, use OpenCV CV2! There are a lot of examples and it’s all object oriented. It’s so much more enjoyable to work with.

I made a quick and dirty web GUI so that I can adjust the HSV values in real-time. It works pretty well.

Tracking objects by HSV colors.

I also built a quick-and-dirty web interface to control the servos. The big motivator here was I replaced the original side-to-side movement with a pan-tilt configuration.

Unfortunately when used together, the board gets reset…. Still trying to figure out why…
