Take image when object is detected

[A.Salcedo]

Hello to everyone.

First of all thanks a lot for reading this post and being able to help.

I have a camera taking images each 0.5 sec (snap vi).

In this images maybe there is an object maybe not.  I am visualizing always this display.

Then I have another display where I would like visualize the picture or taking a photo just when there is a thing.

I know that there is a thing when I dectect it whit a ROI.

Any ideasw to do that?

Thanks a lotª

Hey,

If you are saying that the object is detected as ROI appears on it that means you have done 90 percent of job.Its just a matter of putting a case structure after the method where you are detecting a object and adding a code for saving the image @ particular path.
You can refer 'Snap and Save to File.vi' in Example finder LabVIEW

-How you are detecting it?
-If it's pattern matching or some other matching technique, you can get number of results output and if it's greater than zero pass to case structure as case selector to do selective display.

best and easy method  to start is calculate histogram  if histogram value change  more than thershoding that you select to test it get image
matching algorithm could make your camera slow for this reason  so first work on that
