Abstract
A method is provided for markerless injection of content into an augmented reality scene by use of a mobile device. Through the mobile device, a camera feed of a scene is acquired, which includes a flat surface. A key frame of the flat surface is selected from the feed. After determining that the flat surface in the key frame meets a predetermined level of feature richness, digital content is injected by superimposing text, graphics, video content over at least a part of the key frame. The digital content can be viewed and interacted with by the user of the mobile device. In one embodiment, the digital content is an advertisement.
Claims15
A method of markerless injection of content into an augmented reality scene by use of a mobile device, comprising:
- through the mobile device, acquiring a camera feed of a scene, the scene including a flat surface;
- selecting a key frame of the flat surface from the feed;
- determining that the flat surface in the key frame meets a predetermined level of feature richness;
- and
- injecting digital content by superimposing text, graphics, video content over at least a part of the key frame, and allowing the digital content to be viewed and interacted with by the user of the mobile device,
- wherein injecting digital content further comprises:
- using an optical flow to detect changes in features of the flat surface;
- generating a homography matrix;
- decomposing the homography matrix into two ambiguous cases;
- using knowledge of the normal of the plane to disambiguate the cases and select one correct one;
- and
- calculating a pose estimation for the camera relative to the flat feature rich surface after disambiguation in order to inject the digital content by superimposing it on the flat surface.
