Hi kps,

how and where do you need to match the color of those rings in your images?
Which result do you need to consider?
Best regards,

Hi sir.    Thanks for reply ....I am working in one testing machine.This led color verification is one of the functional test present.Need to switch on the led through modbus communication, capture image through bastler camera , Check the current led color is matching with our master image or not

So there are three clearly defined steps in your approach!

Which of them is giving problems? What have you tried so far? Where are you stuck?

 

I think the color testing might be easier to implement than the two steps before that. As I'm not experienced in IMAQ problems I guess I would compare the colors using the HSV values of the pixels
