This is a quick attempt to track the dot from a red laser pointer.

Right now, the code performs the following steps, and displays the results in several HighGUI windows. The general idea is to:

1. Grab the video frame.
2. Convert it to HSV
3. Split the frame into individual components (separate images for H, S, and V)
4. Apply a threshold to each compenent (hopefully keeping just the dot from the laser)
5. Perform an AND operation on the 3 images (which "should" cut down on false positives)

• Identify the _best location for the identified laser. ie: x,y coordinates in the image.
• Do something interesting with it; e.g. draw a circle around it, control the mouse cursor, build a game, etc.

This requires Python and the Python wrapper for OpenCV.

You'll need to look at the source, but there are global constants at the top of the laser_tracker.py file. You may need to adjust these to suite your situation.

This code is MIT-licensed. You can basically do whatever you want with it.
