pythonEasyOCR库实例⽤法介绍
说明
1、EasyOCR是⼀个⽤python编写的OCR三⽅库。可以在python中调⽤，⽤来识别图像中的⽂字，并输出为⽂本。
2、⽀持80多种语⾔的识别，识别精度⾼，甚⾄要超过PaddleOCR。
安装命令
pip install easyocr
代码实现
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 = adtext(r"d:\Desktop\4A34A16F-6B12-4ffc-88C6-FC86E4DF6912.png", detail = 0)
print(result)
