第一、背景

银行卡，身份证，驾驶证等证件扫描和识别有很广泛的应用场景，比如用户实名认证时。

第二、接入

这里使用百度的文字识别功能。登陆百度的AI开放平台找到文字识别文档。创建一个应用地址
创建好的应用会有三个关键参数。AppID，API Key，Secret Key个会程序里会有使用。

使用SDK
maven引入方式：

<!-- 百度图片识别sdk -->
<dependency><groupId>com.baidu.aip</groupId><artifactId>java-sdk</artifactId><version>${baidu-version}</version>
</dependency>

参数配置类AlibabaMainConfig.java:

package yui.bss.baidu.config;public class AlibabaMainConfig {public static final String APP_ID = "144444951468";public static final String API_KEY = "ahvukw8hqlhoAqqbXrXXXXqPoCyE";public static final String SECRET_KEY = "RqwNLpnH8YwctkkRI07lpv8kpXXXXXXXUFfR";
}

AipOcr是Optical Character Recognition的Java客户端，为使用Optical Character Recognition的开发人员提供了一系列的交互方法。用户可以参考如下代码新建一个AipOcr,初始化完成后建议单例使用,避免重复获取access_token。
配置AipOcr
如果用户需要配置AipOcr的一些细节参数，可以在构造AipOcr之后调用接口设置参数，目前只支持以下参数：

setConnectionTimeoutInMillis：建立连接的超时时间（单位：毫秒）
setSocketTimeoutInMillis：通过打开的连接传输数据的超时时间（单位：毫秒）
setHttpProxy ：设置http代理服务器
setSocketProxy ：设置socket代理服务器（http和socket类型代理服务器只能二选一）

AlipayClientFactory.java:

package yui.bss.baidu.config;import javax.annotation.PostConstruct;import org.apache.log4j.Logger;
import org.springframework.stereotype.Service;import com.baidu.aip.ocr.AipOcr;@Service
public class AlipayClientFactory {private static Logger logger = Logger.getLogger(AlipayClientFactory.class);public static AipOcr client;@PostConstructpublic void postConstruct() throws Exception {logger.info("百度环境初始化开始");// 初始化一个AipOcrAlipayClientFactory.client = new AipOcr(AlibabaMainConfig.APP_ID, AlibabaMainConfig.API_KEY, AlibabaMainConfig.SECRET_KEY);// 可选：设置网络连接参数client.setConnectionTimeoutInMillis(2000);client.setSocketTimeoutInMillis(60000);logger.info("百度环境初始化结束");}
}

创建一个接口，用于外部调用IBaiduImgMgrx.java

package yui.bss.baidu.service;import yui.bss.baidu.bean.BankCardBean;
import yui.bss.baidu.bean.DrivingLicenseBean;
import yui.bss.baidu.bean.IdCardBean;
import yui.bss.baidu.bean.PlateLicense;public interface IBaiduImgMgrx {/*** 通过图片地址url识别身份证信息* * @param imgUrl*/IdCardBean doBaiduIdCard(String imgUrl);/*** 银行卡识别* * @param imgUrl*/BankCardBean doBankCard(String imgUrl);/*** 车牌识别* * @param imgUrl*/PlateLicense doPlateLicense(String imgUrl);/***驾驶证识别* * @param imgUrl*/DrivingLicenseBean doDrivingLicense(String imgUrl);}

接口实现如下BaiduImgMgrxImpl.java:

package yui.bss.baidu.service;import java.util.HashMap;import org.apache.log4j.Logger;
import org.json.JSONObject;
import org.springframework.stereotype.Service;import com.alibaba.fastjson.JSON;import yui.bss.baidu.bean.BankCardBean;
import yui.bss.baidu.bean.DrivingLicenseBean;
import yui.bss.baidu.bean.IdCardBean;
import yui.bss.baidu.bean.PlateLicense;
import yui.bss.baidu.config.AlipayClientFactory;
import yui.comn.util.FileUtil;@Service
public class BaiduImgMgrxImpl implements IBaiduImgMgrx {private static Logger logger = Logger.getLogger(BaiduImgMgrxImpl.class);@Overridepublic IdCardBean doBaiduIdCard(String imgUrl) {// 重写接口方法：2018年3月19日// 传入可选参数调用接口HashMap<String, String> options = new HashMap<String, String>();options.put("detect_direction", "true");options.put("detect_risk", "false");// 通用文字识别, 图片参数为远程url图片byte[] file = FileUtil.readNetImage(imgUrl);JSONObject res = AlipayClientFactory.client.idcard(file, "front", options);IdCardBean idCardFront = JSON.parseObject(res.toString(), IdCardBean.class);return idCardFront;}@Overridepublic BankCardBean doBankCard(String imgUrl) {// 传入可选参数调用接口HashMap<String, String> options = new HashMap<String, String>();options.put("detect_direction", "true");options.put("detect_risk", "false");// 通用文字识别, 图片参数为远程url图片byte[] file = FileUtil.readNetImage(imgUrl);JSONObject res = AlipayClientFactory.client.bankcard(file, options);BankCardBean bankCardBean = JSON.parseObject(res.toString(), BankCardBean.class);return bankCardBean;}@Overridepublic PlateLicense doPlateLicense(String imgUrl) {// 传入可选参数调用接口HashMap<String, String> options = new HashMap<String, String>();options.put("multi_detect", "true");// 通用文字识别, 图片参数为远程url图片byte[] file = FileUtil.readNetImage(imgUrl);JSONObject res = AlipayClientFactory.client.plateLicense(file, options);PlateLicense plateLicense = JSON.parseObject(res.toString(), PlateLicense.class);return plateLicense;}@Overridepublic DrivingLicenseBean doDrivingLicense(String imgUrl) {// 传入可选参数调用接口HashMap<String, String> options = new HashMap<String, String>();options.put("detect_direction", "true");// 通用文字识别, 图片参数为远程url图片byte[] file = FileUtil.readNetImage(imgUrl);JSONObject res = AlipayClientFactory.client.drivingLicense(file, options);DrivingLicenseBean drivingLicenseBean = JSON.parseObject(res.toString(), DrivingLicenseBean.class);return drivingLicenseBean;}
}

}

3.身份证识别结果类IdCardBean.java:

4.驾驶证识别结果类PlateLicense.java:

package yui.bss.baidu.bean;import java.util.List;/*** @author chenyuan* @version 创建时间：2018年3月19日 下午5:20:20* @ClassName 类名称* @Description 类描述*/
public class PlateLicense {private long log_id;private List<Words_result> words_result;public void setLog_id(long log_id) {this.log_id = log_id;}public long getLog_id() {return log_id;}public List<Words_result> getWords_result() {return words_result;}public void setWords_result(List<Words_result> words_result) {this.words_result = words_result;}public static class Words_result {private String color;private String number;public void setColor(String color) {this.color = color;}public String getColor() {return color;}public void setNumber(String number) {this.number = number;}public String getNumber() {return number;}}
}

到此,银行卡，身份证，驾驶证识别信息已经做完.

第三、测试

测试使用springMVC框架写个接口如下:

/*** 身份证图片扫描** @return* @throws Exception*/@RequestMapping(value = "/baiduIdcard", method = RequestMethod.POST)@ResponseBodypublic Object baiduIdcard(@RequestParam(value = "imgUrl", required = true) String imgUrl){try {IdCardBean idCardFront = baiduImgMgrx.doBaiduIdCard(imgUrl);return buildObj(idCardFront);} catch (Exception e) {logger.info("error.", e);return buildFailure("百度身份证验证失败");}}/*** 银行卡扫描** @return* @throws Exception*/@RequestMapping(value = "/bankCard", method = RequestMethod.POST)@ResponseBodypublic Object bankCard(@RequestParam(value = "imgUrl", required = true) String imgUrl){try {BankCardBean bankCardBean = baiduImgMgrx.doBankCard(imgUrl);return buildObj(bankCardBean);} catch (Exception e) {logger.info("error.", e);return buildFailure("银行卡扫描失败");}}/*** 驾驶证识别** @return* @throws Exception*/@RequestMapping(value = "/drivingLicense", method = RequestMethod.POST)@ResponseBodypublic Object drivingLicense(@RequestParam(value = "imgUrl", required = true) String imgUrl){try {DrivingLicenseBean drivingLicenseBean = baiduImgMgrx.doDrivingLicense(imgUrl);return buildObj(drivingLicenseBean);} catch (Exception e) {logger.info("error.", e);return buildFailure("车牌识别失败");}}/*** 车牌识别** @return* @throws Exception*/@RequestMapping(value = "/plateLicense", method = RequestMethod.POST)@ResponseBodypublic Object plateLicense(@RequestParam(value = "imgUrl", required = true) String imgUrl){try {PlateLicense plateLicense = baiduImgMgrx.doPlateLicense(imgUrl);return buildObj(plateLicense);} catch (Exception e) {logger.info("error.", e);return buildFailure("车牌识别失败");}}

结果如下:
1.银行卡图片识别结果,图片地址.
结果如下:

{"data": {"result": {"bank_card_number": "5187 1088 8888 8888", "bank_card_type": 2, "bank_name": "招商银行"}, "log_id": 6611694109754502000}, "status": "200"
}

2.驾驶证识别结果如下(图片地址):

{"data": {"log_id": "7864365883458190264", "words_result": {"certNo": {"words": "440782198905114717"}, "valdTm": {"words": "6年"}, "canCar": {"words": "C1"}, "valdFm": {"words": "20120229"}, "address": {"words": "广东省江门市新会区沙堆镇沙西富成北社13巷21号"}, "name": {"words": "郑嘉荣"}, "country": {"words": "中国"}, "birthday": {"words": "19890511"}, "sex": {"words": "男"}, "first": {"words": "20120229"}}}, "status": "200"
}

3.车牌识别结果如下.图片地址

{"data": {"log_id": 7459084314014470000, "words_result": [{"color": "blue", "number": "赣B2B250"}]}, "status": "200"
}

4.身份证识别结果如下:

{"data": {"log_id": 1647048351325783600, "words_result_num": 6, "direction": 3, "image_status": "normal", "words_result": {"address": {"location": {"width": 501, "top": 962, "height": 1446, "left": 832 }, "words": "浙江省宁波XXXXX"}, "birth": {"location": {"width": 127, "top": 975, "height": 997, "left": 1497 }, "words": "19871210"}, "name": {"location": {"width": 150, "top": 987, "height": 375, "left": 2049 }, "words": "陈X"}, "idCardNum": {"location": {"width": 140, "top": 1543, "height": 1899, "left": 477 }, "words": "43249871210601XXX"}, "sex": {"location": {"width": 0, "top": 0, "height": 0, "left": 0 }, "words": "男"}, "nation": {"location": {"width": 111, "top": 1700, "height": 91, "left": 1767 }, "words": "汉"}, "issueDate": null, "authority": null, "expiryDate": null}, "edit_tool": null, "risk_type": null}, "status": "200"
}
