Hi,

I'm currently trying to track multiple laser dots using my webcam. Tracking one laser works fine, as I can track the brightest pixel on the screen.

However, I need to track 2 laser dots ... I tried using a red laser and a green laser and extracting the red and green values from the pixels in the hope that the highest green value would be where the green laser is pointing and the highest red value is where the red laser is pointing.

Unfortunately, the objects seem to follow only one laser at a time, regardless of the colour they're supposed to be following.

Is it a problem with the method i'm using? Are the objects really just tracking the brighest pixel, even though i'm extracting specific red and green values?

If anybody could shed some light on how I can get this working, I'd be grateful.

Thanks,
H
