Hello I am new to opencv and here's my question, how to communicate with external hardware after detecting a required feature in an image? [closed]
My project is about looking for RGB colors in an image whichever value is greater the respective coloured led must turn on i am using raspberry pi 3b+ basically i need to control a specific pin when a specific color is detected. Thanks for looking into this question:)
That's an interesting question, but I don't think you'll find help here for your 3rd party hardware programming. Did you try stack overflow?
@oja, sjhalayka is right. we can't help with your raspi pins, but we could help with your color detection, if you think it needs improvement. ;)
Thanks for responding @sjhalayka ill go ask the stackoverflow guys,@berak Sure thanks for offering your help
@oja.You must set gpio to 1 if the values is greater the respective to turn led on. Unfortunately, I haven't attempted yet. I am working on robotic.
BTW, you don't need 3rd party hardware programming. You can work both opencv and raspberry pi 3.
Thanks for responding The detection I imagined would be a box pointing the colour so the condition is the occurrence of that box so how do I code it as a condition (need help with the coding)
@oja, we can only mend code, we can actually see, so edit your question, and show, what you have, so far.
Sorry about that I haven't started my project yet as soon as I have a draft I will followup with you guys
@oja.cv2.boxPoints.When the boxPoint is detected, then set gpio pin high to turn led on
