2015-03-03 09:41:58 -0600	commented question	Differentiating laser pointers once detected Thanks for the responses. If anyone feels like converting these comments into an answer then I will mark it as such.
2015-03-03 09:12:23 -0600	commented question	Differentiating laser pointers once detected @theodore There are currently no constraints on types of camera, types of laser or colour of laser, although my assumption was that to effectively do pointer detection I'm going to lose any detail in the visible light range.

2015-03-03 08:03:19 -0600	commented question	Differentiating laser pointers once detected It's still not robust enough. What if several people's pointers leave the screen? They could return in any order. It's heuristics. I'm looking for a stable, repeatable solution such as modulation or wavelength or something...
2015-03-03 06:18:54 -0600	commented question	Differentiating laser pointers once detected This would only work if none of the pointers ever left the camera's view or lost detection and I can't guarantee that.
2015-03-03 05:46:15 -0600	asked a question	Differentiating laser pointers once detected It is my intention to implement a laser pointer detection system, similar to the one described here: http://answers.opencv.org/question/52... However, in my project (a game) I would like multiple (2-10) players to have their pointers on the screen at any given time. What techniques could I use to discern which pointer belongs to which player? I would like to just use one camera for n pointers, rather than a camera per pointer. EDIT: There are currently no constraints on types of camera, types of laser or colour of laser.
