python - Pytesseract does not detect me numbers

Question

I am making a simple program to detect numbers in an image with python and pytesseract, but the case is that it always returns me ♀, I am analyzing an image like this:

my image

and my code to read the numbers is the following:

import pytesseract
from pytesseract import (
    Output,
    TesseractError,
    TesseractNotFoundError,
    TSVNotSupported,
    get_tesseract_version,
    image_to_boxes,
    image_to_data,
    image_to_osd,
    image_to_pdf_or_hocr,
    image_to_string,
    run_and_get_output
)

def analizar_resultado(path): 
    image = cv2.imread(path, 1)
    
    text = pytesseract.image_to_string(image, config = 'digits')
    print('texto detectado:', text)

but I can't make it work for me, I have tried more images of this type with better quality and others, but I can't get any number back, how could I solve this? Thanks a lot

Answer 1

I have a three-step solution

---

• 1. Get each digit separately
• 2. Apply threshold
• 3. Read the output

---

Part-1: Get each digit separately

• You can get each digit by using index variables. For instance:

  • s_idx = 0  # start index
    e_idx = int(w/5) - 10  # end index
    

• First get height and width of the image then for each digit, increase the indexes

  • for _ in range(0, 6):
        gry_crp = gry[0:h, s_idx:e_idx]
        s_idx = e_idx
        e_idx = s_idx + int(w/5) - 20
    

• Result

  • 0	0	9	9	7	6
