腾讯云OCR图片文字识别

一、 OCR

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;

二、腾讯云OCR

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。

三、接口对接

说明:基于 spring boot 的接口对接

1、添加开发的SDK


  com.qcloud
  qcloud-image-sdk
  2.3.6

2、编写工具类

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

import com.qcloud.image.ImageClient;
import com.qcloud.image.exception.AbstractImageException;
import com.qcloud.image.request.*;
import java.io.File;

3、天气太热了

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。
