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.
