python 识别图片中的汉字

我们就识别上面的汉字。

安装软件tesseract和python库

然后新建一个文件夹test,把上面那张图片放在文件夹里面，再新建一个test文件

写入如下内容

#coding=utf-8
from PIL import Image
import pytesseract
#上面都是导包，只需要下面这一行就能实现图片文字识别
text=pytesseract.image_to_string(Image.open('xxx.png'),lang='chi_sim')
print(text)

目录如下：

运行可能会出现错误：

C:\Users\k\Desktop\test>python test.py
Traceback (most recent call last):

    text=pytesseract.image_to_string(Image.open('xxx.png'),lang='chi_sim')

Failed loading language \'chi_sim\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')

因为tesseract-ocr默认不支持中文识别。 将下载到的文件：chi_sim.traineddata 放到Tesseract-OCR安装目录 D:\Program Files (x86)\Tesseract-OCR\tessdata 下

再次运行

python test.py

下面是输出结果

C:\Users\k\Desktop\test>python test.py
风急天高猿啸衷′ 渚麦冒麦少丑弓飞口。
u边洛木萧萧下′ 不〖长江滚滚来。
万 悲禾火常作畜′ 年多病独登台。
艰难苦恨萦霜 渣倒新停澍酉木不=
