Re: How to locate/track a high intensity laser pointer spot on a live video?

An FFT would be computational overkill!

Yes, an optical bandpass filter over the lens, matched to the
frequency of the laser, will find your laser in bright lighting.

However, in your case the laser point will be so much brighter than
the background that a simple adjustment of the gain and contrast of
your camera should provide you with just a single "blob" that you can
threshold against the background.

For more accurate X and Y, you can compute the center of mass of the
blob.

Piece of cake...
