摘要： 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).

摘要： The invention relates to a real-time augmented-reality watching device (300), which comprises an image sensor (335) such as a PTZ camera, a visualisation system (320) and a control interface (310). In this device, the camera is controlled by a control interface operated by the user. Once the user has received (610) orientation information on the desired line of sight from the control interface, the orientation information on the line of sight is transmitted to the camera (615), the camera being powered and capable of movement. Then the camera transmits the orientation of its line of sight (620). The camera transmits a video stream in parallel. The position at which must be inserted data, such as the representation of a virtual three-dimensional object, is determined from the data resulting from the calibration and the orientation of the line of sight of the camera received from the latter (640). The data is further inserted in real time into the video stream that is transmitted to the visualisation system (645). A calibration of the camera is preferably carried out during the device set up (600) in order to improve the device performance.

摘要： 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.
