有人問原始碼:
連結:https://pan.baidu.com/s/1WP37IBacu6VZwtNOUDbSYg 密碼:vdzm
在這
--------------------------------------------------
然後是官方的使用說明文件:地址;
以上,感謝。
首先引入jar:
maven:
<dependency> <groupId>com.baidu.aip</groupId> <artifactId>java-sdk</artifactId> <version>4.3.2</version> </dependency>
然後獲取所需的AppID、APIKey、SecretKey:
進入百度雲,建立應用:
建立完成之後可看見如下:
獲取AppID、APIKey、SecretKey後,匯入一下程式碼:
public class FaceSpot { private static final String AppID = ""; private static final String APIKey = ""; private static final String SecretKey = ""; static AipFace client = null; static { client = new AipFace(AppID, APIKey, SecretKey); // 可選:設定網路連線引數 client.setConnectionTimeoutInMillis(2000); client.setSocketTimeoutInMillis(60000); } public static void main(String[] args) throws IOException { String filePath = "F:/3.jpg"; byte[] imgData = FileToByte(new File(filePath));

// System.out.println(faceverify(imgData1)); } /** * 人臉檢測 * * @return * @throws IOException */ public static String detectFace(File file, String max_face_num) { try { return detectFace(FileToByte(file), max_face_num); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } /** * 人臉檢測 * * @return * @throws IOException */ public static String detectFace(byte[] arg0, String max_face_num) { try { HashMap<String, String> options = new HashMap<String, String>(); options.put("face_field", "age,beauty,expression,faceshape,gender,glasses,race,qualities"); options.put("max_face_num", "2"); options.put("face_type", "LIVE"); // 圖片資料 String imgStr = Base64Util.encode(arg0); String imageType = "BASE64"; JSONObject res = client.detect(imgStr, imageType, options); System.out.println(res.toString(2)); return res.toString(); } catch (Exception e) { e.printStackTrace(); } return null;

JSONObject res = client.updateUser(imgStr, imageType, groupId, userId, options); return res.toString(2); } /** * 刪除使用者人臉資訊 * @param userId * @param groupId * @param faceToken * @return */ public static String deleteUserFace(String userId, String groupId, String faceToken) { HashMap<String, String> options = new HashMap<String, String>();

填入自己的AppID, APIKey, SecretKey;
函式的引數可自行根據官方文件自己改一改,檔案讀取那邊提供一下小帥的FileUtil並且處理好了異常:
public class FileUtil { /** * 根據檔案路徑讀取byte[] 陣列 */ public static byte[] readFileByBytes(String filePath) throws IOException { File file = new File(filePath); if (!file.exists()) { throw new FileNotFoundException(filePath); } else { ByteArrayOutputStream bos = new ByteArrayOutputStream((int) file.length()); BufferedInputStream in = null; try { in = new BufferedInputStream(new FileInputStream(file)); short bufSize = 1024; byte[] buffer = new byte[bufSize]; int len1; while (-1 != (len1 = in.read(buffer, 0, bufSize))) { bos.write(buffer, 0, len1); } byte[] var7 = bos.toByteArray(); return var7; } finally { try { if (in != null) { in.close(); } } catch (IOException var14) { var14.printStackTrace(); } bos.close(); } } } }
然後就是測試啦,測試的話,隨便百度了一張美女的照片,然後看返回:

好,然後通過瀏覽器開啟攝像頭來實時的試下,先上效果圖:
好,大家不用在意這些細節,比如顏值啥的。。
我覺得顏值這項可能是假的,因為我做搞怪的表情時分數反而高一些??????????
上程式碼吧。。
首先是Controller:
@Controller
@RequestMapping(value = "/faceRecognition")
public class faceRecognitionController {
/**
* 人臉檢測測試頁面
* @return
* @throws Exception
*/
@RequestMapping(value = "/test.do")
public ModelAndView queryVoi() throws Exception {
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/artificialIntelligence/faceRecognition/test");
return modelAndView;
}
/**
* 請求人臉檢測
* @return
* @throws Exception
*/
@RequestMapping(value = "/save.do")
@ResponseBody
public Map<String, Object> queryService(@RequestParam("the_file") MultipartFile file) {
Map<String, Object> modelMap = new HashMap<String, Object>();
try {
//將資料轉為流
InputStream content = file.getInputStream();
ByteArrayOutputStream swapStream = new ByteArrayOutputStream();
byte[] buff = new byte[100];
int rc = 0;
while ((rc = content.read(buff, 0, 100)) > 0) {
swapStream.write(buff, 0, rc);
}
//獲得二進位制陣列
byte[] in2b = swapStream.toByteArray();
//呼叫人臉檢測的方法
String str = FaceSpot.detectFace(in2b,""+1);
JSONObject job = new JSONObject(FaceSpot.faceverify(in2b));
System.out.println(job.toString());
JSONObject testData = job.getJSONObject("result");
//System.out.println(testData.get("face_liveness"));
JSON json = JSON.parseObject(str);
FaceV3DetectBean bean = JSON.toJavaObject(json, FaceV3DetectBean.class);
JSONArray arr = new JSONArray();
for(int i=0;i<bean.getResult().getFace_list().size();i++){
JSONObject jsonObject = new JSONObject();
//獲取年齡
int ageOne = bean.getResult().getFace_list().get(i).getAge();
//處理年齡
String age =String.valueOf(new BigDecimal(ageOne).setScale(0, BigDecimal.ROUND_HALF_UP));
jsonObject.put("age", age);
//獲取美醜打分
Double beautyOne = (Double) bean.getResult().getFace_list().get(i).getBeauty();
//處理美醜打分
String beauty =String.valueOf(new BigDecimal(beautyOne).setScale(0, BigDecimal.ROUND_HALF_UP));
jsonObject.put("beauty", beauty);
//獲取性別 male(男)、female(女)
String gender = (String) bean.getResult().getFace_list().get(i).getGender().getType();
jsonObject.put("gender", gender);
//獲取是否帶眼睛 0-無眼鏡,1-普通眼鏡,2-墨鏡
String glasses = bean.getResult().getFace_list().get(i).getGlasses().getType();
jsonObject.put("glasses", String.valueOf(glasses));
//獲取是否微笑,0,不笑;1,微笑;2,大笑
String expression = bean.getResult().getFace_list().get(i).getExpression().getType();
jsonObject.put("expression", String.valueOf(expression));
arr.put(jsonObject);
}
modelMap.put("strjson", arr.toString());
modelMap.put("face_liveness", testData.get("face_liveness"));
modelMap.put("success", true);
} catch (Exception e) {
e.printStackTrace();
modelMap.put("success", false);
modelMap.put("data", e.getMessage());
}
return modelMap;
}
}
用的是fastjson,自行加jar包。
然後是jsp:

這個貌似只支援火狐??我用其他瀏覽器攝像頭並未開啟,有哪位大神知道程式碼還請告訴在下,謝謝指教。
這邊有個活體指數,我測試了下,貌似還挺準,我首先百度了一張胡歌的照片放在攝像頭上,emmmm.....顏值80,但是活體指數就很低,然後本人上,活體指數一直在0.95之上浮動,還是可靠的。
好,告辭!
