METHOD AND DEVICES FOR THE REAL TIME EMBEDING OF VIRTUAL OBJECTS IN AN IMAGE STREAM USING DATA FROM A REAL SCENE REPRESENTED BY SAID IMAGES
First Claim
1. Method for inserting in real time in at least one image, called the first image, of a stream of images representing a real scene (120) at least one image, called the second image, extracted from at least one three-dimensional representation of at least one virtual object, this method being characterized in that it includes the following steps:
- reception of said at least one first image from said image stream;
reception of information for determining the position and the orientation of said at least one virtual object in said real data from said real data being received scene from position and orientation scene, at least a portion of said from at least one sensor (135) present in said real scene;
extraction of said at least one second image from said three-dimensional representation of said at least one virtual object according to said position and said orientation of said at least one virtual object; and
insertion of said at least one extracted second image in said at least one acquired first image according to said position of said at least one object (610).

Abstract
The invention relates to a method and devices for imbedding, in at least one so-called first image of an image stream representing a real scene (120), at least one so-called second image extracted from at least one three-dimensional representation of at least one virtual object. After acquiring said at least one first image of said image stream (210), information for determining the position and the orientation of said at least one virtual object in said real scene using position data from said real scene are received (210, 214), a portion at least of this data being received from at least one sensor (135′, 135′) in the real scene, while other data can be determined by analysis of the first image. Said at least one second image is extracted from the three-dimensional representation of said at least one virtual object according to the orientation of said at least one virtual object. Said at least extracted second image is then imbedded into said at least one first acquired image according to the position of said at least one object (610).
