我正在尝试使用 pytesseract 从图像中读取数据

Question

i tried to open read the image using the pytesseract, however the code is not able to read it please check this photo im using for reading the text.

below is my code:-

import cv2
import time
import pyscreenshot as ImageGrab
import pytesseract
pytesseract.pytesseract.tesseract_cmd=r'C:/Users/RTam/AppData/Local/Programs/Tesseract-OCR/tesseract.exe'

def takescreenshot():
    
    path= (r'C:\Users\RTam\Desktop\python basics\web scraping\Pyautogui\photos')
    im=ImageGrab.grab(bbox=(900,1000,1200,1100))
    
    im.save(path+'\\'+'ss.png')

img= cv2.imread(r'C:\Users\RTam\Desktop\python basics\web scraping\Pyautogui\photos\ss3.png')

cv2.imshow('sample',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

sample_text= pytesseract.image_to_string(img)
print(sample_text)

the only output im getting is and empty space please help

Eventually, I found the answer to my question.

However this code will not run properly in Spyder IDE, so we should make sure we have the latest tesseract version.

import cv2
import time
import pyscreenshot as ImageGrab
import pytesseract
pytesseract.pytesseract.tesseract_cmd=r'C:/Users/RTam/AppData/Local/Programs/Tesseract-OCR/tesseract.exe'

def takescreenshot():
    
    path= (r'C:\Users\RTam\Desktop\python basics\web scraping\Pyautogui\photos')
    im=ImageGrab.grab(bbox=(900,1000,1200,1100))
    
    im.save(path+'\\'+'ss.png')

img= cv2.imread(r'C:\Users\RTam\Desktop\python basics\web scraping\Pyautogui\photos\ss3.png')

def clerify_pic():
    img2 = cv2.resize(img, (0, 0), fx=2, fy=2)
    gry = cv2.cvtColor(img2, cv2.COLOR_BGR2GRAY)
    thr = cv2.threshold(gry, 0, 255, cv2.THRESH_BINARY + cv2.THRESH_OTSU)[1]
    
    
    return pytesseract.image_to_string(thr)
