| 20100002909 | Method and device for detecting in real time interactions between a user and an augmented reality scene - 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 ( | 01-07-2010 |
| 20100045665 | Method and device for creating at least two key frames corresponding to a three-dimensional object - The invention relates to a method and a device for creating at least two key images each including an image representing at least one three-dimensional object in a three-dimensional environment, and the exposure of the object in said environment from the viewpoint of the associated image, said method being characterised in that it comprises the following steps: acquiring a first image representing the object in a a predetermined initial position; creating a first key image from the first acquired image and the relative exposure of the least one second image representing said object, the viewpoint of at least one said second image being different from the viewpoint of said first image; determining the relative exposure of the object in its environment based on the difference between the viewpoints of the first image and at least one said second image, each of said viewpoints being determined relative to a position and an orientation; and creating a second key image based on said at least one acquired second image and the relative exposure of the object in its environment. | 02-25-2010 |
| 20100045700 | DEVICE FOR WATCHING REAL-TIME AUGMENTED REALITY AND METHOD FOR IMPLEMENTING SAID DEVICE - The invention relates to a real-time augmented-reality watching device ( | 02-25-2010 |
| 20100060632 | 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 - 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 ( | 03-11-2010 |
| 20100220891 | AUGMENTED REALITY METHOD AND DEVICES USING A REAL TIME AUTOMATIC TRACKING OF MARKER-FREE TEXTURED PLANAR GEOMETRICAL OBJECTS IN A VIDEO STREAM - The invention relates to a method and to devices for the real-time tracking of one or more substantially planar geometrical objects of a real scene in at least two images of a video stream for an augmented-reality application. After receiving a first image of the video stream ( | 09-02-2010 |

| 20120129605 | METHOD AND DEVICE FOR DETECTING AND TRACKING NON-RIGID OBJECTS IN MOVEMENT, IN REAL TIME, IN A VIDEO STREAM, ENABLING A USER TO INTERACT WITH A COMPUTER SYSTEM - The invention relates in particular to the detection of interactions with a software application according to a movement of an object situated in the field of an image sensor. After having received a first and a second image and having identified a first region of interest in the first image, a second region of interest, corresponding to the first region of interest, is identified in the second image. The first and second regions of interest are compared and a mask of interest characterizing a variation of at least one feature of corresponding points in the first and second regions of interest is determined. A movement of the object is then determined from said mask of interest. The movement is analyzed and, in response, a predetermined action is triggered or not triggered. | 05-24-2012 |

| 20080203237 | Method and Device for Lightening Loads on the Wing System of an Aircraft in Roll Motion - A device used in an aircraft with an electrical flight control system to reduce load applied to the wing during a lateral roll maneuver, by comparing a roll control with a threshold, and filtering a control. As a result of this action on the roll control, resulting load increases on the wing can be anticipated and reduced. Loads can thus remain below a maximum design value for the wing if the applied roll control is too high for planned use of the aircraft, therefore limiting overdesign of the wing. | 08-28-2008 |
