Hi Akki,

Unfortunately you where a little brief in your Problem description. I attached a VI. Is that what you want?

hiii,

Thank you very much for your reply Reschri.

I want to detect two coulor simultaniosly.

could you please explain your vi, what you have done.

I am able to do for one but not for two, and if possible then could you please guide me that how can i measure distance as well.

for example i want to measure distance of any object for example my mobile via usb camera then how can i do so.

Please guide me regarding to this,

thank you very much for your help.

Hi,

it is a little bit difficult to help you her, as I cannot know what exactly you are trying to match.

You seem to have a template called "green.png" and you try to match in your aquired picture. Is the Region of interest perhaps smaller than the template?

I can´t guide you through measuring distance in a general way. Its not a function to just "switch on". To make it work you have to consider many issues an first have to decide, which physical principal you want to use.

For an introduction to the theme:

From your questions I get the impression that you have not much experience with NI Vision and perhaps doing a tutorial first would help, as in the formum we can discuss specific issues but not providing basic training

Thank you very much for your reply.

Yes I am first time dealing with Ni-vision.

I want to match two different color pattern for example green And other red.

I can detect one color easily but when I am trying to detect more then one color then I am getting problem.

So please guide me how to detect more then one color.

I have read the basic tutorials regarding to Ni-Vision.

Thank you very much for your help.

And for distance may be I have to make myself more clear Thank you very much for documentations regarding to that.

Hi AnkitRamani,
Please goto
Help>>Find Examples>>Search>>Color>>Color Classification example.
It has multiple color classification.

Thank you very much for your help and time.

Now I want to make one logic in that when particular color patter is detect then vi should be stop. 

Could you please give me suggestion how to do so.

I tried with logic that Number of matching is not 0 then vi should stop other wise it runs but its not working properly so I am looking for other way to solve this problem.

Thank you very much again for your help.

Sure. Just keep case structure and then based on the condition make stop button value to TRUE if you want to end the code else keep FALSE.
