Adding Multiple Images to UIPageViewController using Camera

it fixes the issue ok, think I got it, i changed the array to pass to the pageviewcontroller from the contentviewcontroller UIImages instead of filename strings.
Also, since the array was nil i didn't start the pageviewcontroller until after the first image was taken or chosen.

Camera calibration across multiple images


Tag : c , By : Paul McKee

wish of those help If said object is a calibration pattern like the chessboard used by OpenCV, then the camera calibration routine mentioned by ChrisO would give you both the camera intrinsics (focal length, principal point, and lens distortion) as well as the camera extrinsics (where they are relatively in space).
If you have general object, then you need to establish a set of 2D correspondences which you can feed into cvFindFundamentalMat. This finds the fundamental matrix which relates the two perspectives. Namely, for each point x in camera 1 and corresponding point x' in camera 2, x'Fx = 0. You can similarly find the epipoles, etc. This uses the 8 point algorithm which requires at least 8 point pairs of point correspondences.

Take multiple images with camera and insert into multiple diffefent imageViews

may help you . , YOU CAN TRY SOMETHING LIKE:
public void onClick(View v) { // TODO Auto-generated method stub

    switch (v.getId()) {

    case R.id.image1:
        i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(i, 1);

        break;
    case R.id.image2:
        ii = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(ii, 2);
  }
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode){
    case 1:
       if(resultCode == RESULT_OK){
          Bundle extras = data.getExtras();
          bmp = (Bitmap) extras.get("data");
          view1.setImageBitmap(bmp);
       }
       break;
    case 2:
       if(resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            bmp = (Bitmap) extras.get("data");
            view2.setImageBitmap(bmp);
        }
       break;
     }
}

How to align multiple camera images using opencv


Tag : python , By : Mossy Breen

should help you out It depends on what you mean by "better" (accuracy, speed, low memory requirements, etc). One classic approach is to align each frame #i (with i>2) with the first frame, as follows:
Local feature detection, for instance via SIFT or SURF (link) Descriptor extraction (link) Descriptor matching (link) Alignment estimation via perspective transformation (link) Transform image #i to match image 1 using the estimated transformation (link)

UIPageViewController for images how to keep aspect-ratio of images when orientation change?


Tag : ios , By : WuJanJai
Date : March 29 2020, 07:55 AM
Any of those help I have a UINavigationController which is the rootviewcontroller of the UIPageViewController, done in the storyboard. The UIViewVontroller is created only by coding. The result works, but when rotation the device the images fill the entire screen and don't keep their aspect-ration. And this looks ugly. , You could set contentMode property for your UIImageView instance:
yourImageView.contentMode = UIViewContentModeScaleAspectFill;
yourImageView.contentMode = UIViewContentModeScaleAspectFit;
