java判断拍照方向,使用FaceDetector google-vision检测到脸部时拍照

你必须在相机API中添加FaceDetectionListener然后调用startFaceDetection()方法，

CameraFaceDetectionListener fDListener = new CameraFaceDetectionListener();

mCamera.setFaceDetectionListener(fDetectionListener);

mCamera.startFaceDetection();

实现Camera.FaceDetectionListener，您在onFaceDetection覆盖方法中接收检测到的面，

private class MyFaceDetectionListener

implements Camera.FaceDetectionListener {

@Override

public void onFaceDetection(Face[] faces, Camera camera) {

if (faces.length == 0) {

Log.i(TAG, "No faces detected");

} else if (faces.length > 0) {

Log.i(TAG, "Faces Detected = " +

String.valueOf(faces.length));

public List faceRects;

faceRects = new ArrayList();

for (int i=0; i

int left = faces[i].rect.left;

int right = faces[i].rect.right;

int top = faces[i].rect.top;

int bottom = faces[i].rect.bottom;

Rect uRect = new Rect(left0, top0, right0, bottom0);

faceRects.add(uRect);

}

// add function to draw rects on view/surface/canvas

}

}

根据你的情况，新的Handler() . postDelayed(新的Runnable，长秒)在5秒后将第二张图片放在runnable中 . 如果您有任何疑问，请告诉我 .
