OCR not working in text rotated

[A.Salcedo]

Hi to all.

I am developing an application which I use OCR.

What i do in the application is:

1- I use IMAQ match pattern 4 VI to find the text in the image inspection.

2- I get ROI where the text is in from the output boubding box of IMAQ match pattern 4.

3- Then I do OCR using IMAQ OCR read text 4.

Everything works fine if the image is not rotated but when the image is rotated IMAQ match pattern 4 works fine (it can find the text rotated in the image) but OCR does not work, it can not find any characters.

By the way I set "text detection" property OCR to true for rotated characters.

Another information is that if I put the ROI manually on the display then OCR works fine... so I think I am doing something wrong getting the ROI and passing it to OCR...

Anybody can help me?

This is the part of my code:

And this is what happens when the image inspection is not rotated:

Ant this when the image is rotated which pattern matchin can find the text but OCR does not work:

Any ideas?

Thanks a lot

While this doesn't directly answer your question, could you simply rotate the image prior to setting the ROI to ensure the text is horizontal?
