python调用tesseract

1 下载tesseract https://github.com/UB-Mannheim/tesseract/wiki
2 pip install pytesseract
3 pytesseract.py 改 tesseract_cmd = r’E:\Tesseract-OCR\tesseract.exe’
4 添加环境变量
TESSDATA_PREFIX = E:\Tesseract-OCR\tessdata
path中 E:\Tesseract-OCR\tessdata E:\Tesseract-OCR
5 重启计算机

一个简单例子

import pytesseract
from PIL import Image
import cv2
import numpy as np
imgpath = "testImg\\1.png"
img = cv2.imread(imgpath,0)
im = Image.fromarray(imgD.astype('uint8')).convert('RGB')
results = pytesseract.image_to_string(im, lang='eng')
print("tesseract结果:", results)
