NI IMAQ Save Image with Number overlay

[nisargsolanki]

Hello All,

I am saving an Image with IMAQ from camera when I click on Snab Button. I am using Edge algorithm to get the distance between two edge points. And I want to save that distance as an Overlay inside the Image.Is it possible!?. Or What is the other way to save that distance with Image itself.

Thanks in Advance:)

Is merge overlay not working?

If it is not, probably you need to make a copy of the image for display, overlays, saving. It can happen that camera is writing to the same image in parallel and overwrites merged overlay with new image.

Also it is advised to post full vi, other parts can affect what is happening here - image is a reference.

Hi Alexander,

Please find the attached VI file.  I am not able to connect IMAQ Merge Overlay with '(Double) Numeric Indicator'.

Convert Distance(Dbl) to string and use IMAQ Overlay Text.vi

Hi,

I am not a 100% sure what you want to do, but perhaps something like that will help you:

You can not just overlay texts, but also lines, points ....

Best regards,

Christoph
