基于百度AI的人脸识别及语音合成课题

课题需求

(1)人脸识别
在Web界面上传人的照片,后台使用Java技术接收图片,然后对图片进行解码,调用云平台接口识别人脸特征,接收平台返回的人员年龄、性别、颜值等信息,将信息返回到Web界面进行显示。
(2)人脸比对
在Web界面上传两张人的照片,后台使用Java技术接收图片,然后对图片进行解码,调用云平台接口比对照片信息,返回相似度。
(3)语音识别
在Web页面上传语音文件,判断语音文件格式,如果不是wav格式进行转码处理,然后调用平台接口进行识别,最后将识别的文本内容返回到Web界面进行显示。
(4)语音合成
在Web界面上传文本内容和语音类型,后台接收文本内容和语音类型后,调用平台接口生成语音数据,最后将数据转码成mp3格式文件,Web界面可以下载到本地。

课题设计

课题基于客户端—服务端-平台端构架,客户端主要实现功能界面展示、数据上传和处理结果展示;服务器端接收客户端数据、数据转码处理、平台接口调用、请求结果相应;平台端介绍服务端数据、人脸识别、人脸比对、语音识别、语音合成等。

接口规范

数据交互类型:JSON
请求数据:请求数据除了请求参数以外,还需另外发送以下参数:(否则会返回403状态码)

返回数据格式:
{"status": "200","msg":"","data": {"namename":"user","password":"password"}}
技术图片

(1)人脸识别
接口名:FaceDetect
请求参数:
技术图片

返回参数:
技术图片

(2)人脸比对
接口名:FaceMatch
请求参数:
技术图片

返回参数:
技术图片

(3)语音识别
接口名:VoiceRecognize
请求参数:
技术图片

返回参数:
技术图片

(4)语音生成
接口名:VoiceGen
技术图片

返回参数:
Mp3音频格式文件

请求注意事项

? 请求体格式化:Content-Type为application/json,通过json格式化请求体。
? Base64编码:请求的图片需经过Base64编码,图片的base64编码指将图片数据编码成一串字符串,使用该字符串代替图像地址。您可以首先得到图片的二进制,然后用Base64格式编码即可。需要注意的是,图片的base64编码是不包含图片头的,如data:image/jpg;base64,
? 图片格式:现支持PNG、JPG、JPEG、BMP,不支持GIF图片

实例代码

1. 人脸识别实例代码

// 配置请求参数
HashMap<String, String> options = new HashMap<String, String>();
options.put("face_field", "age,gender,glasses,beauty,expression");
options.put("max_face_num", "2");
options.put("face_type", "LIVE");
// 转换成base64
String image = Base64Util.part2Base64(imagePart);
String imageType = "BASE64";
// 接口调用,并返回JSON数据
JSONObject json = client.detect(image, imageType, options);
// 响应数据处理
Map<String, Object> map = new HashMap<>();
// 获取人脸信息列表
JSONObject result = json.getJSONObject("result").getJSONArray("face_list").getJSONObject(0);
// 响应数据:性别
JSONObject genderObj = result.getJSONObject("gender");
String genderStr = genderObj.getString("type");
if(genderObj.getDouble("probability") >= 0.6) {//概率并转换
    if("female".equals(genderStr)) {
        genderStr = "女";
    }else if("male".equals(genderStr)) {
        genderStr = "男";
    }
}
map.put("gender", genderStr);
// 返回接口数据
return ResponseData.success(map);

2. 人脸对比实例代码

// 转换成base64
String image1 = Base64Util.part2Base64(imagePart1);
String image2 = Base64Util.part2Base64(imagePart2);
// 封装平台接口请求对象
MatchRequest req1 = new MatchRequest(image1, "BASE64");
MatchRequest req2 = new MatchRequest(image2, "BASE64");
ArrayList<MatchRequest> requests = new ArrayList<MatchRequest>();
requests.add(req1);
requests.add(req2);
// 人脸匹配
JSONObject json = client.match(requests);
// 响应数据处理
Map<String, Object> map = new HashMap<>();
// 匹配分值
double score = json.getJSONObject("result").getDouble("score");
return ResponseData.success(map);

3. 语音识别实例代码

// 文件类型
String fileType = voicePart.getContentType();
if(fileType.endsWith("mp3")) {
    fileType = MP3;
}else if(fileType.endsWith("wav")) {
    fileType = WAV;
}else {
    return ResponseData.fail("请上传mp3、wav音频");
}
try {
    // 获取音频字符流
    InputStream is = voicePart.getInputStream();
    // 保存临时音频文件
    String filename = new SimpleDateFormat("yyyyMMddHHmmssSSS").format(Calendar.getInstance().getTime());
    File tmpVoice = new File(workspace + File.separator + filename+fileType);
    VoiceUtil.saveVoiceFile(is, tmpVoice);
    if(fileType.equals(MP3)) {
        File mp3File = tmpVoice;
        tmpVoice = new File(tmpVoice.getPath().replace(MP3, WAV));
        if(!VoiceUtil.mp3ToWav(mp3File, tmpVoice)) {
            return ResponseData.fail("mp3音频文件错误,请用wav音频。");
        }
        mp3File.delete();
    }
    // 调用百度接口
    JSONObject json = client.asr(tmpVoice.getPath(), "wav", 16000, null);
    tmpVoice.delete();
    Integer status = json.getInt("err_no"); //状态码
    if(status != 0) {
        // 异常响应处理
        String msg = json.getString("err_msg");
        log.warn("百度接口调用响应异常,error_code:"+status + " error_msg:"+msg);
        return ResponseData.fail(msg);
    }
    // 响应数据处理
    Map<String, Object> map = new HashMap<>();
    // 获取结果
    JSONArray jsonArray = json.getJSONArray("result");
    // 识别文本
    String text = jsonArray.getString(0);
    map.put("text", text);
    return ResponseData.success(map);
} catch (Exception e) {
    log.warn("识别音频文件错误:", e);;
}

4. 语音合成实例代码

// 请求参数
HashMap<String, Object> options = new HashMap<String, Object>();
// 语速,取值0-9,默认为5中语速
options.put("spd", "5");
// 音调,取值0-9,默认为5中语调
options.put("pit", "5");
// 发音人选择, 0为女声,1为男声, 3为情感合成-度逍遥,4为情感合成-度丫丫,默认为普通女
options.put("per", voiceType);
// 调用百度api接口
TtsResponse res = client.synthesis(text, "zh", 1, options);
byte[] data = res.getData();
return data;

PS:欢迎大家给予评论、建议和下载学习,下面问源码的一些说明

  • AIProject.zip 为后端代码,为eclipse项目,app.properties文件需要自己配置百度云开发平台的AppID、APIKey、SecretKey。
  • Web.zip 为前端代码,前后端分离,可直接运行使用 。
  • 运行环境,对版本没太大要求,但jdk和tomcat要对应 JDK:,我使用的版本为JDK1.8,官方下载地址
    Tomcat:,我使用的版本为tomcat 9,官方下载地址
  • 注意需要百度云开放平台的AppID、APIKey、SecretKey,百度云AI开放平台:http://ai.baidu.com/
