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 = reader.readtext(r"d:Desktop4A34A16F-6B12-4ffc-88C6-FC86E4DF6912.png", detail = 0) print(result)
