[英]extract the main heading from the image using openCV and Tesseract in python
正如我所说,该代码用于其他用途,但我认为它可以为您提供一段很好的代码。
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
