hi,
I wrote a program with opencv's camera(CvCameraViewListener2) but my program is running so slowly(max 20 fps) on LG G3. However,my program has not any processing.
How can i increase fps or fix it on 24 or 25 fps?
public class activity extends Activity implements CvCameraViewListener2 {
private static final String TAG = "OCVSample::Activity";
private CameraBridgeViewBase mOpenCvCameraView;
private Mat mRgba;
private Mat mGray;
private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
@Override
public void onManagerConnected(int status) {
switch (status) {
case LoaderCallbackInterface.SUCCESS:
{
Log.i(TAG, "OpenCV loaded successfully");
mOpenCvCameraView.enableView();
} break;
default:
{
super.onManagerConnected(status);
} break;
}
}
};
public activity() {
Log.i(TAG, "Instantiated new " + this.getClass());
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "called onCreate");
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setContentView(R.layout.face_detect_surface_view);
mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.fd_activity_surface_view);
mOpenCvCameraView.setCvCameraViewListener(this);
mOpenCvCameraView.setMaxFrameSize(320, 240);
mOpenCvCameraView.enableFpsMeter();
Log.i(TAG, "setMaxFrameSize");
}
@Override
public void onPause()
{
Log.i(TAG, "called onPause");
super.onPause();
if (mOpenCvCameraView != null)
mOpenCvCameraView.disableView();
}
@Override
public void onResume()
{
Log.i(TAG, "called onResume");
super.onResume();
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_9, this, mLoaderCallback);
}
public void onDestroy() {
Log.i(TAG, "called onDestroy");
super.onDestroy();
if (mOpenCvCameraView != null)
mOpenCvCameraView.disableView();
}
public void onCameraViewStarted(int width, int height) {
Log.i(TAG, "called onCameraViewStarted");
mGray = new Mat();
mRgba = new Mat();
}
public void onCameraViewStopped() {
Log.i(TAG, "called onCameraViewStopped");
mGray.release();
mRgba.release();
}
public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
Log.i(TAG, "called onCameraFrame");
mRgba = inputFrame.rgba();
mGray = inputFrame.gray();
return mGray;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
Log.i(TAG, "called onCreateOptionsMenu");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Log.i(TAG, "called onOptionsItemSelected; selected item: " + item);
return true;
}
}
