1.第三方接口
文字识别OCR，需要进行注册和实名认证后，获取对应的应用列表以及免费测试额度
2.调用例子
<!-- 百度识别 --><dependency><groupId>com.baidu.aip</groupId><artifactId>java-sdk</artifactId><version>4.16.11</version></dependency>
package com.alex.examples;import java.util.*;import org.json.JSONException;import org.json.JSONObject;import com.baidu.aip.ocr.AipOcr;public class IDCardSample {//设置APPID/AK/SKpublic static final String APP_ID = "身份证识别的appId";public static final String API_KEY = "身份证识别的apiKey";public static final String SECRET_KEY = "身份证识别的secretKey";public static void main(String[] args) throws JSONException {// 初始化一个AipOcrAipOcr client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);// 传入可选参数调用接口HashMap<String, String> options = new HashMap<>();/*** 检测方向，非必选，默认false* - false：默认值不进行图像方向自动矫正* - true: 开启图像方向自动矫正功能，可对旋转 90/180/270 度的图片进行自动矫正并识别*/options.put("detect_direction", "true");/*** 检测风险，非必选，默认false* 是否开启身份证风险类型(身份证复印件、临时身份证、身份证翻拍、修改过的身份证)检测功能，默认不开启，即：false。* - true：开启，请查看返回参数risk_type；* - false：不开启*/options.put("detect_risk", "false");/*** 必选* -front：身份证含照片的一面* -back：身份证带国徽的一面* 自动检测身份证正反面，如果传参指定方向与图片相反，支持正常识别，返回参数image_status字段为"reversed_side"*/String idCardSide = "back"; //检测：背面//身份证文件：//参数为本地图片路径（也可以是字节流，调用的方法也是client.idcard）String image = "C:\\Users\\86137\\Pictures\\Saved Pictures\\2.jpg";JSONObject res = client.idcard(image, idCardSide, options);System.out.println(res.toString(2));}}
3.效果图如下
//查的是身份证背面/侧面，则返回背面/侧面的信息{"words_result": {"失效日期": {"words": "20390711","location": {"top": 445,"left": 523,"width": 153,"height": 38}},"签发机关": {"words": "陆丰市公安局","location": {"top": 377,"left": 339,"width": 195,"height": 38}},"签发日期": {"words": "0606","location": {"top": 445,"left": 343,"width": 152,"height": 38}}},"log_id": "1559208562721579328","words_result_num": 3,"error_code": 0,"image_status": "normal"}
