Android 虹软人脸识别SDK-人脸对比

准备 :

登录官方网站，获取SDK，进行个人验证后新建项目，获取APP_ID，和SDK_KEY；

实现 :

激活引擎 :

 /**

     *
     * @param view
     */
    public void activeEngine(final View view) {
        if (!checkPermissions(NEEDED_PERMISSIONS)) {
            ActivityCompat.requestPermissions(this, NEEDED_PERMISSIONS, ACTION_REQUEST_PERMISSIONS);
            return;
        }
        if (view != null) {
            view.setClickable(false);
        }
        Observable.create(new ObservableOnSubscribe<Integer>() {
            @Override
            public void subscribe(ObservableEmitter<Integer> emitter) throws Exception {
                FaceEngine faceEngine = new FaceEngine();
                //申请的APP_ID 和ＳＤＫ_key
                int activeCode = faceEngine.active(FaceMainActivity.this, Constants.APP_ID, Constants.SDK_KEY);
                emitter.onNext(activeCode);
            }
        })
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<Integer>() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }

                    @Override
                    public void onNext(Integer activeCode) {
                        if (activeCode == ErrorInfo.MOK) {
                            showToast("OK");
                        } else if (activeCode == ErrorInfo.MERR_ASF_ALREADY_ACTIVATED) {
                            showToast("Not Active");
                        } else {
                            showToast("shibai");
                        }

                        if (view != null) {
                            view.setClickable(true);
                        }
                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onComplete() {
                    }
                });

    }

初始化引擎 :

    private void initEngine() {
        faceEngine = new FaceEngine();
        faceEngineCode = faceEngine.init(this, FaceEngine.ASF_DETECT_MODE_IMAGE, FaceEngine.ASF_OP_0_HIGHER_EXT,
                16, 10, FaceEngine.ASF_FACE_RECOGNITION | FaceEngine.ASF_FACE_DETECT | FaceEngine.ASF_AGE | FaceEngine.ASF_GENDER | FaceEngine.ASF_FACE3DANGLE | FaceEngine.ASF_LIVENESS);
        VersionInfo versionInfo = new VersionInfo();
        faceEngine.getVersion(versionInfo);
        Log.i(TAG, "initEngine: init: " + faceEngineCode + "  version:" + versionInfo);

        if (faceEngineCode != ErrorInfo.MOK) {
            Toast.makeText(this, "TEST", Toast.LENGTH_SHORT).show();
        }
    }

注册相机事件 :

  button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                File outImage = new File(getExternalCacheDir(), "output_image.jpg");
                try {
                    if (outImage.exists()) {
                        outImage.delete();
                    }
                    outImage.createNewFile();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                if (Build.VERSION.SDK_INT >= 24) {
                    uri = FileProvider.getUriForFile(FaceMainActivity.this, "com.example.gdzc.cameraalbumtest.fileprovider", outImage);
                } else {
                    uri = Uri.fromFile(outImage);
                }
                Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
                startActivityForResult(intent, TAKE_POTHO);
            }
        });

显示提示返回结果信息 :

 /**
     * 展示提示信息并且关闭提示框
     *
     * @param stringBuilder 带格式的提示文字
     */
    private void showNotificationAndFinish(final SpannableStringBuilder stringBuilder) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (tvNotice != null) {
                    tvNotice.setText(stringBuilder.toString());
                }
                if (progressDialog != null && progressDialog.isShowing()) {
                    progressDialog.dismiss();
                }
            }
        });
    }

    /**
     * 追加提示信息
     *
     * @param stringBuilder 提示的字符串的存放对象
     * @param styleSpan     添加的字符串的格式
     * @param strings       字符串数组
     */
    private void addNotificationInfo(SpannableStringBuilder stringBuilder, ParcelableSpan styleSpan, String... strings) {
        tvNotice.append(stringBuilder.toString());
        if (stringBuilder == null || strings == null || strings.length == 0) {
            return;
        }
        int startLength = stringBuilder.length();
        for (String string : strings) {
            stringBuilder.append(string);
        }
        int endLength = stringBuilder.length();
        if (styleSpan != null) {
            stringBuilder.setSpan(styleSpan, startLength, endLength, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
    }

人脸验证 :

首先人脸验证需要一个参照的人脸数据，与之后的人脸进行匹配，返回结果为通过与不通过。

 //人脸比对数据显示
            if (faceInfoList.size() > 0) {
                if (type == TYPE_MAIN) {

                            BigDecimal bigDecimal = new BigDecimal(faceSimilar.getScore());
                            if (bigDecimal.compareTo(new BigDecimal(0.8)) >= 0) {
