Finding GPS location of a building from the feature points of an image obtained by using SURF or SIFT algorithm
I am trying to find the GPS location of a building by using it's image. I obtain the feature points of the image by using SURF algorithm. For that, I am using OpenCV for Android.
What I plan to do is with several images of same building, extracting SURF and calibrating cameras (images) we can retrieve "exact" coordinate in the reference world.
But I would like to know if any API exists for this purpose. I can modify the image before sending it to the server as well.
