I’m working on a IR LED tracking system, with few IR LED (less than 10) and a modified webcam,
and my problem is to identify which LED is which.
Kalman filter is not robust enough because each IR LED is not always visible, and I want to be sure that LED ‘x’ stays LED ‘x’ all the time.
I found few solutions:
- let the receiver ask each led separately to emit light, turn-by-turn
- blink each led at different frequency
- the last but my favorite one, is to make some light variation specific to each LED, and then recognize the pattern to identify the led. In this way, I think tracking will be ore efficient because LEDs never stop shining.
Do you know other methods ? which do you think is the best one ?
Considering the third solution, I don’t know what kind of algorithm to use, any clue please ?
Here are some articles I found on the Internet that helped me:
Thanks in advance for interesting.
