Camera pose navigation using Augmented Reality

We propose an Augmented Reality (AR) system that helps users take a picture from a designated pose, such as the position and camera angle of an earlier photo. Repeat photography is frequently used to observe and document changes in an object. Our system uses AR technology to estimate camera poses in real time. When a user takes a photo, the camera pose is saved as a “view bookmark”. To support a user in taking a repeat photo, two simple graphics are rendered in an AR viewer on the camera´s screen to guide the user to this bookmarked view. The system then uses image adjustment techniques to create an image based on the user´s repeat photo that is even closer to the original.
