Problem: Vision Assistant-Measuring area of the Pattern Matching

[ckw0508]

Hi everybody!

I have tried pattern matching of LabVIEW, and it is done.

However, I would like to measure the area of matched image, and I cannot find the way to do so.

Also, is it possible to count the time for the matched image appearing in the screen?

May I have your help? Thank you!!!

Hi ckw0508,

I think this really depends on what shape pattern you are matching. For example if it was a rectangle, there might be a way to do by calibrating your image then using the Clamp (Rake) function to output the calibrated distance. You could then perform the area calculation (LxW) on the block diagram. The other way I thought of doing this is using the Caliper function which I believe would be a similar approach.
