IMAQ OCR read text - Read multiple lines

[shaharl3]

Hi,

I'm trying to read from an image various lines of text which are placed in different areas of the image.

So far I have used for each line a different OCR read text vi with different ROI descriptor.

Is there a way to to use only one OCR read text vi for all lines and make the block diagram more look more elegant and the application run more effectively?

Do I really need to use 20 OCR read text vi's with 20 recatangles for reading 20 different lines?

Thanks,

Shahar

As far as I know - no, its impossible.

Otherwise you don't need to put 20 OCR Read instances on the BD - you can do it with "for loop" with 20 iterations.

Hi Shahar,

As Andrey said it's not possible to have on OCR for several lines - just one per line.

Thank you Andrey and Christian. As you suggested I used a for-loop.

what all should we include within the for loop ? does for loop assign an roi for each line? can u pls post your VI reading multiple lines ?
