Abstract
Described are methods and systems for a viewing system, comprising an augmented reality (AR) system having a first camera with a first point of view, the AR system having an AR display configured to display augmented reality information overlaid over a real world scene, the first point of view of the first camera having a same point of view as the AR display, and the scene containing a first physical object in a field of view of the first camera; a second camera having a second point of view different from the first point of view, wherein the first physical object is in the field of view of the second camera; and a controller configured to: receive an input that the first physical object in the real world scene has become obscured by a second physical object from the first point of view of the first camera; determine a position of the second object that has obscured the first object; determine a perimeter of the second object; display augmented reality information representing the determined perimeter of the second object; extract images from the second camera of the first physical object; and display the extracted images as augmented reality information inside the perimeter of the…
