Method and device for detecting in real time interactions between a user and an augmented reality scene
First Claim
1. Method of detection in real time of at least one interaction between a user and an augmented reality scene in at least one image from a sequence of images, said at least one interaction resulting from the modification of the appearance of the representation of at least one object present in said at least one image, this method being characterized in that it comprises the following steps:
- in an initialization phase,creation of at least one reference model associated with said at least one object;
processing of said at least one reference model;
in a use phase;
determination of the pose of said at least one object in said at least one image;
extraction of at least one comparison model from said at least one image according to said at least one object; and
comparison of said at least one processed reference model and said at least one comparison model as a function of said determined pose and detection of said at least one interaction in response to said comparison step.

Abstract
The invention consists in a system for detection in real time of interactions between a user and an augmented reality scene, the interactions resulting from the modification of the appearance of an object present in the image. After having created (110) and processed (115) a reference model in an initialization phase (100), the pose of the object in the image is determined (135) and a comparison model is extracted from the image (160). The reference and comparison models are compared (170), as a function of said determined pose of the object, and, in response to the comparison step, the interactions are detected.
