這篇文章主要為大家詳細(xì)介紹了python利用百度AI實(shí)現(xiàn)文字識(shí)別，主要涉及通用文字識(shí)別、網(wǎng)絡(luò)圖片文字識(shí)別、身份證識(shí)別等文字識(shí)別功能，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文為大家分享了python實(shí)現(xiàn)文字識(shí)別功能大全，供大家參考，具體內(nèi)容如下

def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
# 定義參數(shù)變量
options = {
 'detect_direction': 'true',
 'language_type': 'CHN_ENG',
}
 
# 調(diào)用通用文字識(shí)別接口
