hi VVVVorum,
i am searching for the cheapest posibility to track two persons on stage (others will be on stage to).
i thought about IR-leds with different flashing rhythm and a cam with IR-filter.
an other solution may be bluetoothing (handy an strength of the signal) or radio bearing or arduino magic …
what do you thing?
the problem may be the changing light (thats why i thought about IR, but may be the theatre spots have IR-light in their spectrum to).
the stage width is about 20 meters.
thanks for your opinions!
