OCR : Microsoft OCR/Cloud OCR/ Abby OCR giving same error : "InvalidImageInput"

ocr

#1

I am trying to extract Text from an image. I have attached the screenshot of my workflow. It gives same error all the time. Let me know if i am doing something wrong or is there anything which is not configured properly.
For abby, i have imported namespace as well, For MODI, i have already installed SharePoint designer and enabled Microsoft Document Imagining Feature. For google i only found , Google Core API and i have imported that namespace. But seems, none of the option is working.


How to get Microsoft or Abby OCR?
#2

Can’t make them work either :frowning:

Tested mainly with Microsoft Cloud OCR.
I’ve used the same exact image from UiPath and from normal C# code.

The latter works normally (although the results are not that great).

The former throws an InvalidImageInput for all configurations I could think of - passing UiPath.Core.Image, System.Drawing.Image, loading from file, using the activity GetOcrText with nested engine, using the engine activity directly… always same result :frowning:

Known issue. Will be fixed.


#4

Yes Andrzej.

I did all that tries, But no luck.

This would be the great feature, it helps a lot in some business cases.

Hi,

I am getting the same error: “MicrosoftErrorCreateEngine”, even when I use the example from UiPath site.

I have tried to used Google OCR and it works fine.

Any ideas?

#12

I reinstalled SharePoint designer and now Microsoft OCR is work fine.:grin:


#13

I am using UiPath Studio Community version 2016.2.6253 Beta on a Windows 7.
Tried with beta and without beta and I can only get it working with Google OCR, Microsoft OCR always throws that Exception. It looks like it needs a dll or something like that but even in the logs no info is given in that way.


#14

I have still same problem. Only Google OCR is working. I have version 2016.2.6274.
So is there way to fix it or go around the problem?


#15

make sure you have the SharepointDesigner2007 properly installed


#16

dear,

If we do not install SharePoint Designer, can we still use “Microsoft OCR” function? thanks~


#17

It comes preinstalled with Windows 10. Otherwise you can install it from here Uipath - Install MS Office OCR.


#18

#19

I have “Abbyy OCR : Error performing OCR: AbbyyErrorLoadEngine”.
Does anyone have the same issue? All other OCR engines are working.
Maybe I need to install something before?


#20

yes, abbyy engine, with a license :slight_smile:
