Hi Albert and Fangao
I would also like to know more of working model.
Could a flashing IR be read by a laser, to determine position on a model railway layout of a locomotive. Each IR with its own code.
Thanks
Charlie

Hi,
I want to locate/track a high intensity laser pointer spot on a live
video.
* A web camera with USB interface is connected to a PC running Fedora
Core 5 Linux (and optionally Windows XP pro). The camera is pointed to
a wall which is used as the projection screen.
* One red and one green laser pointers are pointed to the screen at
pseudo random locations. Laser are activated randomly for a duration
of 50-2000 milli second.
* Intensity of the laser pointers' spots are significantly brighter
then the any texture/image on the wall.
I want to locate the laser pointer spots (ie. find the X,Y position of
the laser pointer spots) in image frame and track them at video frame
rate.
I wonder if there is an open-source C/C++ code for Linux (and Windows)
which can locate/track bright spots (option of selecting color would
be even better) on a live color video from a USB web camera?
Regards,
Albert
