OCR Not detecting numbers

Post by psiquetp » Tue Jul 24, 2018 2:07 pm

Hi, I'm trying to detect the row where a given number is found

In this image...

But OCR is only reading the value of 10 as in this output:
The value 30 was not found in the table. ...
| 806,248,863,273 > 10 | 806,281,863,306 > | 806,314,863,339 >
| 806,347,863,372 > 10
| 806,380,863,405 > 10
| 806,413,863,438 > | 806,446,863,471 > | 806,479,863,504 > | 806,512,863,537 >
| 806,545,863,570 > 10
| 806,578,863,603 > | 806,611,863,636 > | 806,644,863,669 > | 806,677,863,702 > | 806,710,863,735 >
This is the code

Code: Select all

//Subroutine to find a text in a given table ------------------------------------------
//Const: BASE_DIRECTORY       .- Directory where the macro has its files.
//Const: IMAGES_SUB_DIRECTORY .- Directory inside the BASE_DIRECTORY where the macro has the images to be searched for.
//Input: IMAGE_NAME           .- Name of the Image with a pic of the header at the top of the column.
//Input: COL_WIDTH            .- Width of the column in pixels.
//Input: ROW_HEIGHT           .- Height of the row in pixels.
//Input: ROW_SKIP_PIXELS      .- Number of Pixels to skip before finding the next row
//Input: FILE_LINE_INDEX      .- See ReadFileVariable
//Outpt: FILE_VAR_TEXT        .- See ReadFileVariable
//Outpt: X_CORD,X2_CORD       .- Horizontal coordinates of the found item
//Outpt: Y_CORD,Y2_CORD       .- Vertical coordinates of the found item
SRT>FindInTable
  //Retrieve text to be found
  Let>FILE_VAR_TEXT=30

  ArrayCount>YArr,NUM_IMGS_FOUND
  Let>ARR_IDX=0
  Let>X_CORD=0
  Let>Y_CORD=0
  Let>VAR_LOG_FIND_IN_TABLE=...

  //Find header
 FindImagePos>%BASE_DIRECTORY%\%IMAGES_SUB_DIRECTORY%\%IMAGE_NAME%,SCREEN,0.7,3,XArr,YArr,NumFound,CCOEFF
  IF>NumFound>0
    While>ARR_IDX<15
      Let>X_CORD=%XArr_0%
      Let>Y_CORD={%ARR_IDX%*%ROW_HEIGHT%}
      Add>Y_CORD,{%ARR_IDX%*%ROW_SKIP_PIXELS%}
      Add>Y_CORD,%YArr_0%
      Let>X2_CORD=%X_CORD%
      Add>X2_CORD,%COL_WIDTH%
      Let>Y2_CORD=%Y_CORD%
      Add>Y2_CORD,%ROW_HEIGHT%
      OCRArea>%X_CORD%,%Y_CORD%,%X2_CORD%,%Y2_CORD%,STR_OCR_RESULT
      Let>VAR_LOG_FIND_IN_TABLE=%VAR_LOG_FIND_IN_TABLE% | %X_CORD%,%Y_CORD%,%X2_CORD%,%Y2_CORD% > %STR_OCR_RESULT%
      Trim>%STR_OCR_RESULT%,STR_OCR_RESULT
      //Message>|%STR_OCR_RESULT%| != |%FILE_VAR_TEXT%|
      IF>STR_OCR_RESULT=FILE_VAR_TEXT
        Goto>ContinueFindInTableNoError
      EndIf
      Let>ARR_IDX={%ARR_IDX%+1}
    EndWhile
  Endif
  Let>ERROR_MESSAGE=The value %FILE_VAR_TEXT% was not found in the table. %VAR_LOG_FIND_IN_TABLE%
  GoSub>ReportError
  Label>ContinueFindInTableNoError
  Let>ROW_SKIP_PIXELS=0
END>FindInTable

//Find the POS
//Outpt: X_CORD,X2_CORD       .- Horizontal coordinates of the found item
//Outpt: Y_CORD,Y2_CORD       .- Vertical coordinates of the found item
Let>IMAGE_NAME=pap_08_oc_pos_right_click.PNG
Let>COL_WIDTH=57
Let>ROW_HEIGHT=25
Let>FILE_LINE_INDEX=9
Let>ROW_SKIP_PIXELS=8
GoSub>FindInTable
Is there something I can change on the OCR to work with numbers? This same code seems to be doing it fine with another table of letters...

Thank you!

Anybody can help?

I tried a different approach... I'm creating little pieces of screen images

Code: Select all

      ScreenCapture>X_CORD,Y_CORD,X2_CORD,Y2_CORD,%NEW_IMAGE_FILE_NAME%
      OCRImage>%NEW_IMAGE_FILE_NAME,STR_OCR_RESULT      
Even though the cut image looks perfect OCR is not finding any text

Have you tried increasing OCR_SCALEFACTOR. Not sure why it needs it, but this works for me, against your image showing on the imgr website:

Code: Select all

Let>OCR_SCALEFACTOR=10
OCRArea>612,280,665,315,strText
