OCR （Optical Character Recognition，光学字符识别）是指电子设备（例如扫描仪或数码相机）检查纸上打印的字符，通过检测暗、亮的模式确定其形状，然后用字符识别方法将形状翻译成计算机文字的过程；
-- 来自百度基于腾讯自研的深度学习技术和海量的数据，提供卡证、票据类印刷体和手写体、自定义模板等多种场景和类型的文字识别服务。说明：基于 spring boot 的接口对接
<!-- 腾讯云cos_api -->
<dependency>
<groupId>com.qcloud</groupId>
<artifactId>cos_api</artifactId>
<version>5.4.10</version>
</dependency>注意：此接口对接版本有点低，现在的sdk是2.0了，不过这个工具类是可以正常食用的。2.0的sdk可以官方给出的文档 传送门

上面的工具类只是简单的说了一下，如果项目需要用到，得自己去测试，等我那天心情好了再说详细了点。
