使用Python3 Pytesseract进行实时屏幕监控

Question

我正在Windows 10上的python3项目中工作，我想知道是否有人知道通过pytesseract传递opencv屏幕抓取？如果没有，您还有其他OCR吗？

这是opencv屏幕抓取的代码：

import numpy as np
from PIL import ImageGrab
import cv2



while True:
    screen =  np.array(ImageGrab.grab(bbox=(0,40,800,640)))
    cv2.imshow('window', cv2.cvtColor(screen, cv2.COLOR_BGR2GRAY))
    if cv2.waitKey(25) & 0xFF == ord('q'):
        cv2.destroyAllWindows()

Answer 1

我对pytesseract知之甚少，但这可能会让您入门：

#!/usr/bin/env python3

import numpy as np
from PIL import ImageGrab
import pytesseract
from PIL import Image, ImageEnhance, ImageFilter
from textblob import TextBlob

# Grab some screen
screen =  ImageGrab.grab(bbox=(0,0,800,640))
# Make greyscale
w = screen.convert('L')

# Save so we can see what we grabbed
w.save('grabbed.png')

text = pytesseract.image_to_string(w)
correctedText = TextBlob(text).correct()

print(correctedText)
