Rotate camera preview to Portrait Android OpenCV Camera

Question

I am trying to use OpenCV 2.4.3.2 to create a camera app and do some opencv processing. I would like it to be able to have multiple UI orientations, not just Landscape.

Answer 1

I`ve got portrait orientation with CameraBridgeViewBase, but I had to change JavaCameraView.java inside the OpenCV :( The idea is next: after camera init, do next

setDisplayOrientation(mCamera, 90);
mCamera.setPreviewDisplay(getHolder());

and setDisplayOrientation method

protected void setDisplayOrientation(Camera camera, int angle){
    Method downPolymorphic;
    try
    {
        downPolymorphic = camera.getClass().getMethod("setDisplayOrientation", new Class[] { int.class });
        if (downPolymorphic != null)
            downPolymorphic.invoke(camera, new Object[] { angle });
    }
    catch (Exception e1)
    {
    }
}
