Creating a panoramic photo

I want to be able to create a panoramic photo app or something that will be able to stitch multiple photos together (much like google photo sphere), but before I start I want to get a bit more information how it is done.

Is it done using the UIImagePickerController framework?

Is there any other useful API's or anything out there I can use?

Can somebody give me a brief overview of how this works.

There is no available native API with stitching algorithm. You should dig into the 3rd party OpenCV library and check their stitcher documentation

Basic Key steps of stitching algorithm:

  • Detect keypoints in each input image (eg. Harris corners) and extract the invariant descriptors of the images (eg. SIFT)
  • Match the descriptors between images
  • Using RANSACcalculate the homography matrix and apply the transformation
