百度OCR体验地址:
https://ai.baidu.com/tech/imagerecognition/general
腾讯OCR体验地址:
https://cloud.tencent.com/act/event/ocrdemo
测试结果是:腾讯的效果要比百度的好
腾讯云目前(2020年2月16日)额度是:
每个接口 1,000次/月免费,有6个文字识别的接口,一共是6,000次/月
百度接口调用之前写过文章
Python编程:通过百度文字识别提取表格数据
使用步骤
步骤:
1、注册账号:
https://cloud.tencent.com/
2、开通服务:
https://console.cloud.tencent.com/ocr/general
3、申请访问秘钥:
https://console.cloud.tencent.com/cam/capi
4、通过 API 或 SDK 或命令行来使用服务
具体参考《操作指南》:
https://cloud.tencent.com/document/product/866/17622
接口使用
1、安装SDK
https://github.com/TencentCloud/tencentcloud-sdk-python
pip3 install tencentcloud-sdk-python
2、代码实例

微服务应用中图片、文件等存储区别于单体应用,单体应用可以放到本地读写磁盘文件,微服务应用必需用到分布式存储,将图片、文件等存储到服务稳定的分布式存储服务器。目前,很多云服务商提供了存储的云服务,比如阿里云OSS、腾讯云COS、七牛云对象存储Kodo、百度云对象存储BOS等等、还有开源对象存储服务器,比如FastDFS、MinIO等。
超级快速使用阿里云OSS或腾讯COS及七牛云Koa获取、放置、删除对象
Supper quick use Aliyun OSS or Tencent COS or Qiniu Koa to get、put、delete Object.
