注册百度账号及新增一个应用，获取百度API所需的AppID，API Key，Secret Key三个参数。

1. 访问http://ai.baidu.com，使用百度账号登录后，出现如下界面

   

   • 创建成功创建应用后，出现类似如下界面：

   

2. 下载百度SDK
   • https://ai.baidu.com/sdk#ocr中，下载java SDK

   

3. 集成百度SDK
   • 身份证中文字识别代码如下，简单几行代码就搞定，具体如下：

package com.chinalife.maced_bdsdk.util;
 
import com.baidu.aip.ocr.AipOcr;
import org.json.JSONObject;
 
import java.util.HashMap;

public class Sample {
    // TODO APP_ID/AK/SK
    public static final String APP_ID = "23552975";
    public static final String API_KEY = "CS6wkhbrmjhiu9KUx2f6E51t";

    /**

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        // 初始化一个AipOcr
        AipOcr client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);
 
        // 可选：设置网络连接参数
        client.setConnectionTimeoutInMillis(2000);
        client.setSocketTimeoutInMillis(60000);
 
        // 传入可选参数调用接口
        HashMap<String, String> options = new HashMap<>();
        options.put("detect_direction", "true");
        options.put("detect_risk", "false");
        // 识别身份证正面（正面图片为本地图片，即：C:\Users\yy150\Pictures\正.jpg）
        JSONObject frontres = client.idcard("C:\\Users\\yy150\\Pictures\\正.jpg", "front", options);
        System.out.println(frontres.toString(2));
        // 识别身份证反面（反面图片为本地图片，即：C:\Users\yy150\Pictures\反.jpg）
        JSONObject backres = client.idcard("C:\\Users\\yy150\\Pictures\\反.jpg", "back", options);
        System.out.println(backres.toString(2));
    }
 
}

4. 运行Sample中main()方法，运行后的结果，大致如下：
   • 备注：识别出来的文字，为了安全起见，用***********代替。

// 正
