Opencv+Pytesseract实现OCR识别

1.1下载tesseract-OCR工具包：

https://github.com/UB-Mannheim/tesseract/wiki

1.2安装时注意勾选中文

1.3注意安装位置，获取执行程序路径：C:\\Program Files\\Tesseract-OCR\\tesseract.exe

1.4在conda环境中安装相关依赖：opencv和pytesseract

pip install pytesseract -i https://pypi.tuna.tsinghua.edu.cn/simple

1.5Vscode中创建python文件，执行以下代码

import cv2 
import pytesseract

pytesseract.pytesseract.tesseract_cmd = r'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'
img = cv2.imread('chinese_paper.jpg')
img = cv2.cvtColor(img,cv2.COLOR_BGR2RGB)
text = pytesseract.image_to_string(img, lang='chi_sim')
print(text)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

1.6执行效果展示(我这里用的vscode+notebook)
