I suggest you take a look at the example that comes with VBAI, then if you have more specific questions about image processing, maybe the "Machine Vision" section of the forum will be more appropriate.

Thank you for your response.

I checked the example programs and tried to implement them to my requirement.

But nothing seems to work properly for my application.

Can you help me through the task to complete .

Thanking you.

In the next block of functions perform continuous capture of images and show it in the indicator function RGB images using Vision Express (parameters to control zoom, focus, contrast, etc.), then extract the image plane Original leaving a grayscale image (8 bits)

In the following function block proceed to perform the extraction of the pattern with a function for image processing that captures the last event of the RGB (extract image and coordinates)

In the following we proceed to function block search pattern extracted in the previous process (the parameters as rotation angle and minimum score is inserted into SETTINGS control), extract the output of the search function to get the position values indicators that will be displayed on the front panel)
