python: easyocr的安装和使用(easyocr 1.6.2 / Python 3.7.15 )

一，安装easyocr：

1，官网:

https://www.jaided.ai/

项目代码地址:

https://github.com/JaidedAI/EasyOCR

通过pip安装:

[root@blog ~]# pip3 install easyocr

查看已安装的easyocr的版本:

二，下载并安装模型

1,模型的官方地址:

https://www.jaided.ai/easyocr/modelhub/

2,官方站的下载很慢，我转存到了百度网盘，链接:

https://pan.baidu.com/s/13VsP9RbbTEguJtCl812XEA?pwd=lstn

提取码:lstn

3,下载模型后安装:

• Linux：放到此目录下 ~/ .EasyOCR / model
• 例子：

[lhdop@blog model]$ pwd
/home/lhdop/.EasyOCR/model
[lhdop@blog model]$ ls
chinese_sim.pth  craft_mlt_25k.pth  english_g2.pth  zh_sim_g2.pth

如果不手动下载安装model,

则第一次运行时会自动下载,

例：运行：

[lhdop@blog img2]$ python3 easy.py
CUDA not available - defaulting to CPU. Note: This module is much faster with a GPU.
Downloading detection model, please wait. This may take several minutes depending upon your network connection.    

说明：这个时间非常漫长，建议手动下载

三，编写代码

easy.py

import easyocr
 
reader = easyocr.Reader(['ch_sim','en'])
result = reader.readtext(r'/home/lhdop/img2/text.jpeg')
print(result)

四，测试代码

返回结果:

[lhdop@blog img2]$ python3 easy.py
CUDA not available - defaulting to CPU. Note: This module is much faster with a GPU.
