注意事项

SDK里用到了高德SDK辅助定位，请在App项目中的AndroidManifest.xml中修改相对应的key

SDK使用方法

1) 初始化SDK

  1. SDK.init({context}, {app}, {appid}, {appsecret})

2) 注册回调事件

  1. SDK.registerAiCountingListener(r -> Log.e("number>>", "onNumEnd: " + r.items.size()));

3) 启动AI点数

  1. SDK.aiCounting()

删除监听

  1. SDK.unregisterAiCountingListener()

注意事项

a) 点数完成后，SDK不会主动退出拍摄界面，开发者可以根据以下代码获取当前Activity，并手动退出当前Activity

Activity currentCameraSession = getActivity()
b) 点数时，会有一段采样的时间，采样完毕后会自动进行结束回调
c) 回调返回信息包括图片，猪坐标以及图片旋转角度信息。
d) 请打开项目的NDK支持以及Renderscript支持

脸部识别接口

初始化SDK时，需调用setHttpFaceidQueuedCallbackAddr(建库成功回调) 和 setHttpFaceidMatchedCallbackAddr(比对结果回调) 来设置脸部识别系统的HTTP回调接口

新建脸部采集（新建识别池）

  1. SDK.startNewFaceCapture(PoolInfo info)
  2. class PoolInfo{
  3.     public String custom_id;
  4.     public String pool_name;
  5.     public Dictionary<String, String> extra;
  6.     public PoolType pool_type;
  7.     public bool dup_check; //是否开启重复采集检查
  8. }

从已有识别池继续采集

  1. SDK.continueFaceCapture(String pool_id)

脸部比对

  1. SDK.faceRecognition(String pool_id)

删除脸部信息

  1. SDK.faceDelete(String pool_id, String face_id)

离线队列

SDK采集采用自适应离线队列后台上传机制，无法连接上网路则自动停止上传任务，直到连接上网络为止。

  1. 获取离线队列排队数据
  2. List<CaptureInfo> offlineData = OfflineQueue.sharedQueue().Get()
  3. 暂停离线队列上传
  4. OfflineQueue.sharedQueue().Pause()
  5. 恢复离线队列上传
  6. OfflineQueue.sharedQueue().Resume()
  7. 查看离线队列是否运行
  8. OfflineQueue.sharedQueue().Running()

CaptureInfo数据结构

  1. public class BasicCaptureInfo {
  2.     public String type;    // 类型，比对: match 或者是 采集: capture
  3.     public String pool_id; // 识别池id
  4.     public String pool_type;    // 识别池类型，cow, yak, sheep, pig 等等
  5. }

采集监听

  1. SDK.registerCaptureSessionListener(new SDK.CaptureSessionDoneCallback() {
  2.     @Override   //识别池创建
  3.     public void onPoolCreated(Map<String, Object> o) {
  4.     }
  5.     @Override   // 已入MQ的采集信息
  6.     public void onCapturePrequeued(Map<String, Object> o) {
  7.     }
  8.     @Override   //建库完成，不一定每次都能收到，以服务器回调为准
  9.     public void onClaimDone(Map<String, Object> o) {
  10.         /**
  11.         {
  12.             'pool_id': {pool_id},
  13.             'face_id': {face_id},
  14.             'pool_type': {},
  15.             'duplicated': {True/False},
  16.             'cover_url': {cover}
  17.         }
  18.         **/
  19.     }
  20. });

控制牛脸采集输入

  1. SDKConfigs.SetCaptureInputFeature(true/false);

脸部识别监听

  1. SDK.registerAiMatchListener(new SDK.AiFaceMatchDoneCallback() {
  2.     @Override   // 已入MQ的比对信息
  3.     public void onAiFaceMatchPrequeued(Map<String, Object> o) {
  4.     }
  5.     @Override  // 服务器比对完成回调，不一定每次都能收到，以服务器回调为准
  6.     public void onDone(AiFaceMatchDone done) {
  7.     }
  8. });

脸部比对后台回调接收数据格式
建库成功

  1. {
  2.         'face_id': face_id,                 //牛脸ID
  3.         'pool_id': pool_id,                 // 识别池ID
  4.         'type': pool['pool_type'],          // 识别池类型
  5.         'info': pool['pool_info'],          // 识别池信息
  6.         'duplicated': dup,                  // 是否为重复采集
  7.         'noncer': ranstr(5)                 //随机字符串
  8. }

比对成功

  1. {
  2.     'similarity': 1,
  3.     'cover': e,
  4.     'info': {
  5.         'face_id': matched['id'],
  6.         'cover': matched['cover'],
  7.         'lat': matched['loc'][1],
  8.         'lng': matched['loc'][0],
  9.         'state': matched['state'],
  10.         'entrypoint': matched['entrypoint'],
  11.         'percentage': get_cosine_similarity
  12.     },
  13.     'timetag': time.time()
  14. }

未找到匹配

  1. {
  2.     'similarity': 0,
  3.     'cover': e,
  4.     'info': {},
  5.     'timetag': time.time()
  6. }

加密规则

加密协议 32BLOCK ECB + 自定义Padding
解密顺序:
1. AES ECB 解密(no padding)
2. unpad(密文)

  1. const unpad = (text) => {
  2.     var t = ''
  3.     var c = ord(text[text.length - 1])
  4.     var l = text.length - c
  5.     for(var i=0;i<l;i++){
  6.         t += text[i]
  7.     }
  8.     return t
  9. }
  10. const ord = (text) => {
  11.     var str = text + ''
  12.     var code = str.charCodeAt(0)
  13.     if (code >= 0xD800 && code <= 0xDBFF) {
  14.         var hi = code
  15.         if (str.length === 1) {
  16.             return code
  17.         }
  18.         var low = str.charCodeAt(1)
  19.         return ((hi - 0xD800) * 0x400) + (low - 0xDC00) + 0x10000
  20.     }
  21.     if (code >= 0xDC00 && code <= 0xDFFF) {
  22.         return code
  23.     }
  24.     return code
  25. }
