一、使用pytesseract识别图片中的问题-11

1、安装pytesseract

• 目录：d:\python\lib\site-packages

C:\Users\jieqiong>pip install pytesseract

pytesseract requires Python '>=3.7' but the running Python is 3.6.5
You are using pip version 9.0.3, however version 22.2.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

2、运行报错

D:\imooc\selenium\read_image.py

# coding=utf-8

# 识别图片的包
import pytesseract
# 取图片的包
from PIL import Image

# 需要一个图片的对象，并打开图片
image = Image.open("D:/imooc/imooc2.jpg")

# 运用包，将对象image转换成字符串
text = pytesseract.image_to_string(image)
print(text)

PS D:\imooc\selenium> python .\read_image.py
TesseractNotFoundError: tesseract is not installed or it's not in your PATH. See 
README file for more information.

 

3、安装tesseract-ocr

Tesseract-OCR 安装、中文识别与训练字库 - 简书 (jianshu.com)

C:\Users\jieqiong>tesseract -v
tesseract 4.00.00alpha
 leptonica-1.74.1
  libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.5.0) : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0

 

4、修改后的代码

# coding=utf-8

# 识别图片的包
import pytesseract

tesseract_cmd =  'D:\Python\Tesseract-OCR'

# 取图片的包
from PIL import Image

# 需要一个图片的对象，并打开图片
image = Image.open("D:/imooc/imooc2.jpg")

# 运用包，将对象image转换成字符串
text = pytesseract.image_to_string(image)
print(text)

PS D:\imooc\selenium> python .\read_image.py
