Trying to ocr some values on chart in real time(once per minute) and buy/sell securities on basis of alert generated in my software.
I am struck onto few steps.
1. On Tesseract Screen Capture indentation parameters. How can we determine the exact parameters if I just want numeric values only.
2. The Tesseract Screen Capture generates and error Obj1 on line 185 which needs to be resolved.
3. Sometimes lines get overlapped with values. What to do in that case.
3. Detecting the sound as and when it approaches and then comparing the ocr values to decide on either buy or sell.
The values that needs to be fetched are encircled.
I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR. Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results. An ideal hash key for this cache would be a checksum of the captured image. With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR.
Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile(). But that's still slower than I would like, and it shouldn't be necessary. Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all. In order to do that, I need a way to dump a representation of the image into a string (or some equivalent). Then I could use the _Crypt_HashData() function against that string to create my cache hash key.
Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing. This was the closest thing I found to what I'm trying to do. I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about. If someone could give me a shove in the right direction it would be a big help. Thanks!
Im new here and interested in tesseract ocr.
There are many examples in the forum but too difficult to me .
I just want to see how its working in few line cod .
I have installed tesseract and microsoft office 2003 .
$ImageToReadPath = @MyDocumentsDir & "\GDIPlus_Image10.jpg"
$ResultTextPath = @MyDocumentsDir & "\Result"
$OutPutPath = $ResultTextPath & "auto.txt"
;$TesseractExePath = @ProgramsDir & "\Tesseract.exe"
$TesseractExePath =@ProgramFilesDir & "\Tesseract-OCR\tesseract.exe"
ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE)
If @error Then
Exit MsgBox(0, "Error", @error)
MsgBox(0, "Result", FileRead($OutPutPath))
Please help me.
i have this picture here *attached* and this script here:
$ImageToReadPath = @MyDocumentsDir & "\GDIPlus_Image2.jpg" $ResultTextPath = @MyDocumentsDir & "\Result" $OutPutPath = $ResultTextPath & ".txt" $TesseractExePath = @MyDocumentsDir & "\Tesseract.exe" ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE) If @error Then Exit MsgBox(0, "Error", @error) EndIf MsgBox(0, "Result", FileRead($OutPutPath)) FileDelete($OutPutPath)
but tesseract doesnt recognized the correct word... and gives me trash back...
this is the image >>
and the result was >> "samm"
the image was an normal jpg and generated with this code here:
_ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image2.jpg", 712,268,853,284)
Could anybody give me a hint what i can do better to get this easy image to text?
thank u very much!!!
Edit: i also tried to capture the screen as bmp with a higher resolution... nothing changed...
_ScreenCapture_SetBMPFormat(4) _ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image.bmp", 712,279,853,295)
I'm trying to get Tesseract to work using the example script here: https://www.autoitscript.com/forum/topic/174483-tesseract-simple-example/ Downloading the script and running it with the example image just gives me a blank readout. Someone else had the same problem here: https://www.autoitscript.com/forum/topic/174476-single-dll-file-for-ocr/#comment-1263034 but doesn't provide an explanation of how they fixed it. Has anyone else experienced this problem and know of a fix?
