AutoIt and OCR?

12 posts in this topic

Hello,

I am new to the forums, and AutoIt, and I have a question. How do I use OCR with AutoIt? After some searching, I found that Tesseract would be a suitable solution, but on my test script I get this error:

So does anyone know what I can use for OCR? The image I need to read is below:

Regards.

This is a problem with the UDF's code. You should try and ask the author directly.

Thanks, I'll try, but do you know of any other OCR UDFs?

modi ocr...you need to download the driver from Microsoft (part of the sharepoint distributer...it's free)...then, you can use it's api...google vbs modi, and it will show you how, that's easy to then convert to au3

what is the reason?  There are much easier/better/more accurate ways to get text

There is no real way to tell where the problem lies with only an error message, it might manifest itself from the UDF, but all manner of things might be wrong with your own code which causes it.

In short: Show your code, or a short reproducer that others can run.

I will add to this. I have tried this UDF () and it takes a long time to parse the data and then it is only about 15-25 percent right, it seems to get the first 15-20 chars right and then drifts off to garbage...I am wondering if there is another way of doing this. I am going to look and see about vbs modi, if I get it working, I will post.

@jdelaney -->> can you tell me an easy was to grab text from a window? I have an image basically and need to be able to get the text fast. Even when I tried the above UDF - it took to long, I might as well used the export from the window, as that would be faster. It exports to an excel file, but no hot keys to allow automation.

I use this:

Func Var_OCRGet($Image, $Lang=9) ; Get the OCR text
    $giSubFunctionCounter += 1
    If $gbPerformLog Then Var_SetLogAndActOnState(2, $gbLogLevel_Strt, "Var_OCRGet()", "Func=[Var_OCRGet]: Start with Params=[" & $Image & "].", $gbDisplayInformMessage, $gbTerminateOnFailure)

    Local $sArray[1], $oWord
    Local $oErrorHandler = ObjEvent("AutoIt.Error", "Var_ErrFunc")
    If IsObj ( $oErrorHandler ) Then
        If $gbPerformLog Then Var_SetLogAndActOnState(2, 3, "Var_OCRGet()", "Func=[ObjCreate]: able to create ObjEvent=[" & "AutoIt.Error" & "].", $gbDisplayInformMessage, $gbTerminateOnFailure)
    Else
        If $gbPerformLog Then Var_SetLogAndActOnState(0, $gbLogLevel_Rtrn, "Var_OCRGet()", "Func=[ObjCreate]: UNable to create ObjEvent=[" & "AutoIt.Error" & "].", $gbDisplayInformMessage, $gbTerminateOnFailure, False)
        $giSubFunctionCounter -= 1
        $miDoc = ""
        $oErrorHandler = ""
        Return SetError(1)
    EndIf

    Local $miDoc = ObjCreate("MODI.Document")
    If IsObj ( $miDoc ) Then

        $giSubFunctionCounter -= 1

        Return SetError(1)
    EndIf

    $miDoc.Create($Image)
    If Not @error Then
        If $gbPerformLog Then Var_SetLogAndActOnState(2, 3, "Var_OCRGet()", "Func=[ObjCreate]: able to run method=[" & "$miDoc.Create" & "].", $gbDisplayInformMessage, $gbTerminateOnFailure)

        $oErrorHandler = ""
        Return SetError(2)
    EndIf

    Sleep (2000)

    $miDoc.Ocr($Lang, True, False)
    If Not @error Then
        If $gbPerformLog Then Var_SetLogAndActOnState(2, 3, "Var_OCRGet()", "Func=[.Ocr]: able run method=[" & "$miDoc.Ocr" & "].", $gbDisplayInformMessage, $gbTerminateOnFailure)
    Else
        If $gbPerformLog Then Var_SetLogAndActOnState(0, $gbLogLevel_Rtrn, "Var_OCRGet()", "Func=[.Ocr]: UNable run method=[" & "$miDoc.Ocr" & "].", $gbDisplayInformMessage, $gbTerminateOnFailure, False)
        $giSubFunctionCounter -= 1
        $miDoc = ""
        $oErrorHandler = ""
        Return SetError(3)
    EndIf

    For $oWord In $miDoc.Images(0).Layout.Words
        ReDim $sArray[UBound($sArray)+1]
        $sArray[UBound($sArray)-1] = $oWord.Text
    Next
    $sArray[0] = UBound($sArray)-1
    If $gbPerformLog Then Var_SetLogAndActOnState(2, 3, "Var_OCRGet()", "Func=[Var_OCRGet]: returning array of text=[UBound=(" & UBound ( $sArray ) & ")].", $gbDisplayInformMessage, $gbTerminateOnFailure)
    $giSubFunctionCounter -= 1
    $miDoc = ""

    Return $sArray
EndFunc

You would need to comment out quite a bit.

My only problem is that I do not have MODI installed on these computers - work inviroment. Not sure why they would not install it by default, but that is what happened. Maybe when we get our new computers in April LOL, they will have it installed. Until then, I go back to my trusted, send('{tab}') - I really hate when developers do not use Microsoft GUI's

Sorry if I highjacked this thread, but all the other threads were over 2 years old.

Does it matter where it's from? It's just an example of what I need to read with the OCR. :P

Well it looks like a game image, that's why I asked. Secondly, it does matter, due to the fact there might be a different approach to obtaining the time other than the image. "Many hands make light work"

Though your cocky response leads me to think you're breaking the rules.
