real time color pattern matching

[BlueBill]

I am doing a project of color pattern matching in real-time. I want the pattern that is matched with the templete shows on the screen. I was trying to write some labview code but it only works for the first single image. The labview i use is 8.6. camera is the ieee 1394b firewire camera. I hope someone is capable of fixing my problem.

Thanks for any help.

Hi blue hill,

Can you post your vi for lv 8.0? or a screen shot of ur vi?

[BlueBill]

hi muks,

I dont have 8.0 version. Here is the screen shot.

Thanks.

What is the match score that you have set? Ideally 600-700 is the score that was recommended as a rule of thumb.

[BlueBill]

I didn't set the score. Yes, 700 can be as the minimum.

I just modified my vi a little bit. It can work well for the single picture on my computer. Both the image and templete image can be opened, and the detected image can be marked. Once I tuned the code to make it work for the images caputred by camera, the templete image seemed not be opened. I used the probe to find that.

Thanks for any help,

Hi! I'm tring to use Imaq Setup Learn Color pattern Vi. It has a tunnel in : Ignore color spectra. I read many posts, manuals, all of vision manuals ::) but i dont really understand how to use it. " For
example, by replacing the last component in the color spectrum with –1, the
white color is ignored during the color matching process.
". OK , but how to do that? anyway, i read this : Use the Color Sensitivity control of the IMAQ ColorLearn VI to
specify the granularity you want to use to represent the colors".  So, what I wanna do , how to use the color spectrum array (2dim) from Imaq Color Learn  as an input to the Imaq Setup Learn Color pattern vi, avoiding the error messasge like this : 

Please help!
