Hi,

Update: Since LED's appear really tiny once the drone starts moving away, is there some way to get around this ? Example, Is it possible to use the Region of Interest (ROI) (of the original LED) near the LED (assume ROI is given), if I extract the LED in the ROI , can I get the pixel coordinates of the extracted LED center in the original image ?

======

Original Question:

I wish to track (using external cameras) some LED strips ( see this for the exact LED type) on my UAV.

Are there any existing methods in OpenCV for tracking/detecting LEDs specifically ?

Thanks!

"quite bright, different coloured LEDs are not very distinguishable" -- what ? you must be doing something wrong then. show us, please.

Hi, I have now updated the question. what I meant earlier was that their colour was too bright (for the given camera) and being recognized as white colour (in RGB, HSV, LAB, etc all colour spaces) but I've found a crude fix to this currently, ie, using a resistor in series with the LED to reduce the brightness.
