利用Python和百度开放API接口，写一个文字或表格识别软件

990708

在论坛看到了有人分享截图识别软件的制作，就想到把自己以前做的一个表格和文字识别的软件分享出来
但由于本人菜鸟编程水平，没有做后续的优化，有能力的大佬可以优化代码

代码中GUI绘制用的是PYQT5及相关的模块，代码测试好后用pyinstaller打包成exe使用

打开后输入app_id，api_key，api_secret后选择文件，然后选择图片开始识别，推荐使用高精度的，准确率较高，但是每日免费次数较少
成品自带我自己的免费接口，等哪天我想起来打开百度开放API的时候就关了吧
表格识别因为百度接口原因只能在识别结果网址中下载打开，本人水平有限

我想起来了各位，虽然现在用的人不多，但是我等小屁民还是怕免费次数超标，所以今天我就把api关闭了。
各位如果有时间的话可以自己申请一个使用，https://cloud.baidu.com/doc/OCR/s/Ek3h7xypm。
可以去看下官方文档创建一个应用即可使用。望君前程似锦！

你们的百度API都是无限次免费的吗？

不是啊，每天有限制的，返回不了信息可能程序就崩溃了吧

老哥可以拿走去做个毕设嘛

可以，你自己再优化一下吧，写的比较粗超
