1、EasyOCR是一個(gè)用python編寫的OCR三方庫(kù)。可以在python中調(diào)用，用來(lái)識(shí)別圖像中的文字，并輸出為文本。

2、支持80多種語(yǔ)言的識(shí)別，識(shí)別精度高，甚至要超過(guò)PaddleOCR。

pip install easyocr代碼實(shí)現(xiàn)

import easyocr #設(shè)置識(shí)別中英文兩種語(yǔ)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)
