Abstract
Methods, systems and devices for augmenting a real scene in a video stream are disclosed herein.
Claims16
A method for augmenting a real scene, the method comprising:
- receiving a first image from a video stream of the real scene, wherein the first image includes an object to be tracked;
- determining a pose of the object being tracked in the first image;
- determining a geometrical model of the real scene;
- calculating a geometrical relationship between the object and the geometrical model of the real scene;
- adding an animated virtual object to the video stream, wherein the animated virtual object moves as a function of the geometrical model of the real scene;
- and
- displaying the video stream including the animated virtual object.

A method for augmenting a real scene, the method comprising:
- receiving a first image from a video stream of the real scene, wherein the first image includes an object to be tracked;
- determining a pose of the object being tracked in the first image based on a comparison between the pose of the objected being tracked and a plurality of image blocks, wherein each image block of the plurality of image blocks is associated with a unique pose;
- receiving a second image from the video stream, wherein the second image includes the object being tracked;
- evaluating the pose of the object being tracked in the second image based on the plurality of the image blocks;
- determining a geometrical model of the real scene;
- calculating a geometrical relationship between the object being tracked and the geometrical model of the real scene;
- adding an animated virtual object to the video stream, wherein, the animated virtual object
- moves as a function of the geometrical model of the real scene;
- and
- displaying the video stream including the animated virtual object.

A method for augmenting a real scene, the method comprising:
- locating a textured area in a first image from a video stream of the real scene;
- tracking the textured area in subsequent images from the video stream;
- adding a virtual image to the video stream, wherein the virtual image is positioned at a location of the textured area being tracked;
- and
- displaying the video stream including the virtual image.
