效果图
激活引擎
第一步配置APP_ID和SDK_KEY
int activeCode = FaceEngine.activeOnline( ChooseFunctionActivity.this, Param.APP_ID, Param.SDK_KEY);
public static final String APP_ID = "AwY6okHQHxtM92YRYSEqJQwb8cED5huPvYyMhK1w7BSo"; public static final String SDK_KEY = "AF8SaLYtP3ALsmaTR55y9UXaykBZjTtMt5gwCBkUGugh";
第二步：判断是否添加动态链接库（so文件与jar包）
private boolean checkSoFile(String[] libraries) {
File dir = new File(getApplicationInfo().nativeLibraryDir);
File[] files = dir.listFiles();
if (files == null || files.length == 0) {
return false;
}
List<String> libraryNameList = new ArrayList<>();
for (File file : files) {
libraryNameList.add(file.getName());
}
boolean exists = true;
for (String library : libraries) {
exists &= libraryNameList.contains(library);
}
return exists;
}
第三步：判断是否申明所有权限
protected boolean CheckPermissions(String[] neededPermissions) {
if (neededPermissions == null || neededPermissions.length == 0) {
return true;
}
boolean allGranted = true;
for (String neededPermission : neededPermissions) {
allGranted &= ContextCompat.checkSelfPermission(this, neededPermission) == PackageManager.PERMISSION_GRANTED;
}
return allGranted;
}
激活引擎代码如下
public void ActivationDevice(final View view) {
if (!libraryExists) {
ShowToast(getString(R.string.library_not_found));
return;
}
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) {
RuntimeABI runtimeABI = FaceEngine.getRuntimeABI();
Log.i(TAG, "subscribe: getRuntimeABI() " + runtimeABI);
long start = System.currentTimeMillis();
int activeCode = FaceEngine.activeOnline( ChooseFunctionActivity.this, Param.APP_ID, Param.SDK_KEY);
Log.i(TAG, "subscribe cost: " + (System.currentTimeMillis() - start));
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(getString(R.string.activation_succeeded));
} else if (activeCode == ErrorInfo.MERR_ASF_ALREADY_ACTIVATED) {
ShowToast(getString(R.string.already_activated));
} else {
ShowToast(getString(R.string.active_failed, activeCode));
}
if (view != null) {
view.setClickable(true);
}
ActiveFileInfo activeFileInfo = new ActiveFileInfo();
int res = FaceEngine.getActiveFileInfo(ChooseFunctionActivity.this, activeFileInfo);
if (res == ErrorInfo.MOK) {
Log.i(TAG, activeFileInfo.toString());
}
}
@Override
public void onError(Throwable e) {
ShowToast(e.getMessage());
if (view != null) {
view.setClickable(true);
}
}
@Override
public void onComplete() {
}
});
}
人脸比对 1：N
第一步：初始化本地人脸库
FaceServer.getInstance().init(this);
第二步：初始化引擎和相机
public void onGlobalLayout() {
previewView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
if (!CheckPermissions(NEEDED_PERMISSIONS)) {
ActivityCompat.requestPermissions(this, NEEDED_PERMISSIONS, ACTION_REQUEST_PERMISSIONS);
} else {
initEngine();
initCamera();
}
}
第三步：初始化引擎
private void initEngine() {
ftEngine = new FaceEngine();
ftInitCode = ftEngine.init(this, DetectMode.ASF_DETECT_MODE_VIDEO, ConfigUtil.getFtOrient(this),
16, MAX_DETECT_NUM, FaceEngine.ASF_FACE_DETECT);
frEngine = new FaceEngine();
frInitCode = frEngine.init(this, DetectMode.ASF_DETECT_MODE_IMAGE, DetectFaceOrientPriority.ASF_OP_0_ONLY,
16, MAX_DETECT_NUM, FaceEngine.ASF_FACE_RECOGNITION);
flEngine = new FaceEngine();
flInitCode = flEngine.init(this, DetectMode.ASF_DETECT_MODE_IMAGE, DetectFaceOrientPriority.ASF_OP_0_ONLY,
16, MAX_DETECT_NUM, FaceEngine.ASF_LIVENESS);
Log.i(TAG, "initEngine: init: " + ftInitCode);
if (ftInitCode != ErrorInfo.MOK) {
String error = getString(R.string.specific_engine_init_failed, "ftEngine", ftInitCode);
Log.i(TAG, "initEngine: " + error);
ShowToast(error);
}
if (frInitCode != ErrorInfo.MOK) {
String error = getString(R.string.specific_engine_init_failed, "frEngine", frInitCode);
Log.i(TAG, "initEngine: " + error);
ShowToast(error);
}
if (flInitCode != ErrorInfo.MOK) {
String error = getString(R.string.specific_engine_init_failed, "flEngine", flInitCode);
Log.i(TAG, "initEngine: " + error);
ShowToast(error);
}
}
第四步：活体检测
private void initCamera() {
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
final FaceListener faceListener = new FaceListener() {
@Override
public void onFail(Exception e) {
Log.e(TAG, "onFail: " + e.getMessage());

if (faceFeature != null) {

Integer liveness = livenessMap.get(requestId);
//不做活体检测的情况，直接搜索
if (!livenessDetect) {
searchFace(faceFeature, requestId);
}
//活体检测通过，搜索特征
else if (liveness != null && liveness == LivenessInfo.ALIVE) {
searchFace(faceFeature, requestId);
}
//活体检测未出结果，或者非活体，延迟执行该函数
else {
if (requestFeatureStatusMap.containsKey(requestId)) {
Observable.timer(WAIT_LIVENESS_INTERVAL, TimeUnit.MILLISECONDS)
.subscribe(new Observer<Long>() {
Disposable disposable;
@Override

@Override

}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
getFeatureDelayedDisposables.remove(disposable);
}
});
}
}
}
//特征提取失败
else {
if (increaseAndGetValue(extractErrorRetryMap, requestId) > MAX_RETRY_TIME) {
extractErrorRetryMap.put(requestId, 0);
String msg;

requestFeatureStatusMap.put(requestId, RequestFeatureStatus.FAILED);
retryRecognizeDelayed(requestId);
} else {

@Override
