patern match indicator

[DMJeff]

Hi all,

I'm using Vision Assistant to work out a strategy for my project.

In the Vision Assistant, if I select pattern matching, define the pattern, and capture images, when I apply the script with pattern matching, a red square is displayed on the end result image showing where the patter exists on the image.  All that is working welll.

So, I worked with parameters, and I can get the location I need most of the time (not all of the time).

So, I told the Vision Assistant to export the code to LabVIEW 2013.  That went well.

I then grabbed the code and ran it, and I can read from an AVI file, change it to gray scale, apply the edge detection, and get the X,Y location of the image.

That's all good.

However, in the exported code, I don't see the red box displayed on the image, as it had appeared in the Vision Assistant.

To be sure that the LabVIEW is identifying the right location, I'd like to be able to show this visual indicator when playing back stored AVI files.

Any suggestions as to how I can see the 'pattern match' indicator on the end result image?

Thanks,

Jeff

Hi K,

Thanks, that is exactly what I needed.

I had done a search of the forum before posting the question, but that answer wasn't an exact match to the search.

Thanks for pointing it out.

In this illustrative example, we will create a program in Labview capture an image pattern, after the search to show the location and coordinates, you can check the following article in the following link
