CameraSource (vision api) ne pas détecter lorsque le téléphone est en mode paysage

Question

J'ai créé une application pour suivre les yeux en utilisant Vision api et son fonctionnement bien lorsque le téléphone est en mode portrait, mais quand je tilde le téléphone en position paysage puis l'application pauses la caméra et est allé à la méthode onMissing().

S'il vous plaît me donner quelques suggestions afin que l'application peut fonctionner dans les deux mises en page ou il peut sentir les yeux de toute rotation de téléphone (0,90,180,270)

code:

private void createCameraResources() { 
    Context context = getApplicationContext(); 

    // create and setup the face detector 
    mFaceDetector = new FaceDetector.Builder(context) 
      .setProminentFaceOnly(true) 
      .setTrackingEnabled(true) 
      .setClassificationType(FaceDetector.ALL_CLASSIFICATIONS) 
      .setMode(FaceDetector.FAST_MODE) 
      .build(); 

    mFaceDetector.setProcessor(new LargestFaceFocusingProcessor(mFaceDetector, new FaceTracker())); 

    if (!mFaceDetector.isOperational()) { 
     Log.w(TAG, "createCameraResources: detector NOT operational"); 
    } else { 
     Log.d(TAG, "createCameraResources: detector operational"); 
    } 
    mCameraSource = new CameraSource.Builder(this, mFaceDetector) 
      .setRequestedPreviewSize(640, 480) 
      .setFacing(CameraSource.CAMERA_FACING_FRONT) 
      .setRequestedFps(30f) 
      .build(); 
} 



public class FaceTracker extends Tracker<Face> { 

private static final float PROB_THRESHOLD = 0.7f; 
private static final String TAG = FaceTracker.class.getSimpleName(); 
private boolean leftClosed; 
private boolean rightClosed; 

@Override 
public void onUpdate(Detector.Detections<Face> detections, Face face) { 
    if (leftClosed && face.getIsLeftEyeOpenProbability() > PROB_THRESHOLD) { 
     leftClosed = false; 
    } else if (!leftClosed && face.getIsLeftEyeOpenProbability() < PROB_THRESHOLD){ 
     leftClosed = true; 
    } 
    if (rightClosed && face.getIsRightEyeOpenProbability() > PROB_THRESHOLD) { 
     rightClosed = false; 
    } else if (!rightClosed && face.getIsRightEyeOpenProbability() < PROB_THRESHOLD) { 
     rightClosed = true; 
    } 

    if (leftClosed && !rightClosed) { 
     EventBus.getDefault().post(new LeftEyeClosedEvent()); 
    } else if (rightClosed && !leftClosed) { 
     EventBus.getDefault().post(new RightEyeClosedEvent()); 
    } else if (!leftClosed && !rightClosed) { 
     EventBus.getDefault().post(new NeutralFaceEvent()); 
    } 
}

Vous devez vérifier un changement d'orientation et faire quelque chose comme,

private void startIfReady() throws IOException { 
    if (mStartRequested && mSurfaceAvailable) { 
     mCameraSource.start(mSurfaceView.getHolder()); 
     if (mOverlay != null) { 
      Size size = mCameraSource.getPreviewSize(); 
      int min = Math.min(size.getWidth(), size.getHeight()); 
      int max = Math.max(size.getWidth(), size.getHeight()); 
      if (isPortraitMode()) { 
       // Swap width and height sizes when in portrait, since it will be rotated by 
       // 90 degrees 
       mOverlay.setCameraInfo(min, max, mCameraSource.getCameraFacing()); 
      } else { 
       mOverlay.setCameraInfo(max, min, mCameraSource.getCameraFacing()); 
      } 
      mOverlay.clear(); 
     } 
     mStartRequested = false; 
    } 
} 

@Override 
protected void onLayout(boolean changed, int left, int top, int right, int bottom) { 
    int width = 320; 
    int height = 240; 
    if (mCameraSource != null) { 
     Size size = mCameraSource.getPreviewSize(); 
     if (size != null) { 
      width = size.getWidth(); 
      height = size.getHeight(); 
     } 
    } 

    // Swap width and height sizes when in portrait, since it will be rotated 90 degrees 
    if (isPortraitMode()) { 
     int tmp = width; 
     width = height; 
     height = tmp; 
    } 

private boolean isPortraitMode() { 
    int orientation = mContext.getResources().getConfiguration().orientation; 
    if (orientation == Configuration.ORIENTATION_LANDSCAPE) { 
     return false; 
    } 
    if (orientation == Configuration.ORIENTATION_PORTRAIT) { 
     return true; 
    } 

    Log.d(TAG, "isPortraitMode returning false by default"); 
    return false; 
}
