overlay ROI and OCR results on a image

[JuanC]

Hi, Im doing a label inspection, and I want to display on the control panel an image of the last photo with the ROI and the OCR result like it appears on the Vision development module. Does anybody kwons if there is some tool to do that?

Hi Juan,

What you can do is to use IMAQ Overlay ROI and IMAQ Merge ROI in the same way it is shown in the VI attached to this post. For the OCR there are similar ways to do that, which is an overlay of that information to the main image. Once you have done this the new image can be displayed in the way you prefer so that it meets the requirements of your application!

Good Luck!

Hi, Luis, thanks for your help, unfurtenly I couldnt open the Save image.vi because I have the 2009 Labview version, and your vi is on 2010. Do you have this example on the 2009 version?

Hi Juan,

I saved the VI for labview 2009, hopefully you can use it now! Additionally I give you this link regarding some work in Optical Character Recognition, in this explanation there is a ZIP to download which has a VI called "overlaysubvi.vi". This VI may help you a lot in the task of implementing OCR overlay in your program!
