正如我所说的，代码是用来做其他事情的，但我认为它可以为你提供一段很好的代码来使用。

import numpy as np
from PIL import ImageGrab
from PIL import Image
import cv2
import time
import pytesseract

p1 = 520
p2 = 760
p3 = 1450
p4 = 830

# Those points are pixel points you will need to adjust for your frame 


while(True):
        frame = np.array(ImageGrab.grab(bbox=(p1 ,p2 , p3, p4)))
        frame = cv2.bitwise_not(frame)
        cv2.imshow("window", frame)
        pytesseract.pytesseract.tesseract_cmd = r'Path\to\tesseract.exe'
        txt = pytesseract.image_to_string(frame)
        str_num = re.findall(r'.*', txt)
        print(txt)
        print(str_num)
        print("-----------")
        if cv2.waitKey(25) & 0xFF == ord('q'):
            cv2.destroyAllWindows()
            break
