当前个人部署服务器，输入图片识别

python的easyocr怎么提高识别率_html

http://39.107.76.144/

即可访问，注意：图片太大ocr不支持会报错

环境以及代码如下：

1.安装EasyOCR，pip install easyocr

python的easyocr怎么提高识别率_flask_02 

import easyocr

#设置识别中英文两种语言
reader = easyocr.Reader(['ch_sim','en'], gpu = False) # need to run only once to load model into memory
result = reader.readtext(r"d:\Desktop\4A34A16F-6B12-4ffc-88C6-FC86E4DF6912.png", detail = 0)
print(result)

初次运行需要在线下载检测模型和识别模型，建议在网速好点的环境运行

2.安装flask，pip install flask

3.前端代码
