我是一个甜甜的大橙子🍊，欢迎关注✉️！ 我相信技术的力量💪 努力将所学分享给大家😎 你的点赞❤️分享🚀收藏📖就是对我最大的鼓励！ 1.效果选择要识别的类型，然后导入图片，利用百度API，完成图像中的文字识别，将结果显示在右侧，并且可以将识别结果复制到剪贴板。
在代码中找到AK和SK，替换成2.1中自己的API Key和Secret Key即可。 AK = 'API_KEY' SK = 'SECRET_KEY'完整代码 # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'face_recognition.ui' # # Created by: PyQt5 UI code generator 5.15.4 # # WARNING: Any manual changes made to this file will be lost when pyuic5 is # run again.
