1、EasyOCR是一個用python編寫的OCR三方庫。可以在python中調用，用來識別圖像中的文字，并輸出為文本。

2、支持80多種語言的識別，識別精度高，甚至要超過PaddleOCR。

pip install easyocr代碼實現

import easyocr #設置識別中英文兩種語言reader = easyocr.Reader([’ch_sim’,’en’], gpu = False) # need to run only once to load model into memoryresult = reader.readtext(r'd:Desktop4A34A16F-6B12-4ffc-88C6-FC86E4DF6912.png', detail = 0)print(result)

實例擴展：

圖文提取的代碼
