Abstract: A device and a method are provided for analyzing the behavior of a subject moving in an operational environment during a mission, including: synchronized acquisition of a plurality of raw data relating to the subject, to the operational environment and to the mission; on-the-fly cross-processing of the acquired raw data; and real-time generation of processed data from the cross-processing operations, providing instantaneous information about the state and the behavior of the subject; the device is characterized in that all or some of the steps may be implemented so as to activate various operating modes of analyzing and monitoring the behavior of the subject.

Abstract: A device is provided for locating a moving object or person in a space partially equipped with inductive surfaces. The device comprises magnetic detection means configured to detect the presence of the object or of the person on or close to an inductive surface, measure a heading angle by way of two simultaneous measurement points and generate dated reference heading angle data for the object or for the person; inertial detection means configured to generate estimated angular speed and acceleration data for the object or for the person; and calculation means coupled to the magnetic and inertial detection means, configured to combine the dated reference heading angle data with the estimated data in order to generated corrected position and orientation data for the object or for the person in the space.

Abstract: The present invention relates to a method for generating motion controls for a mobile platform of a vehicle simulator. The method uses, as input, accelerations calculated by a process for simulating the behavior of the vehicle. The method according to the invention comprises the steps of: filtering the accelerations calculated accelerations by use of a filter constructed according to a mathematical model of human perception of a motion; calculating successive positions of the mobile platform as a function of the filtered acceleration controls; scaling the positions of the mobile platform as a function of physical limitations of the mobile platform, to produce scaled successive positions of the mobile platform; and calculating acceleration controls to be applied by the mobile platform, as a function of the scaled successive positions of the mobile platform, to produce calculated acceleration controls.

Abstract: A method for synchronizing at least two video streams originating from at least two cameras having a common visual field. The method includes acquiring the video streams and recording of the images composing each video stream on a video recording medium; rectifying the images of the video streams along epipolar lines; extracting an epipolar line from each rectified image of each video stream; composing an image of a temporal epipolar line for each video stream; computing a temporal shift value ? between the video streams by matching the images of a temporal epipolar line of each video stream for each epipolar line of the video streams; computing a temporal desynchronization value Dt between the video streams by taking account of the temporal shift values 6 computed for each epipolar line of the video streams; synchronizing the video streams by taking into account the computed temporal desynchronization value Dt.

Abstract: A method for dynamic generation of synthetic images employs Delaunay mesh generation. Only the terrain portions of which a significant variation in the detail level takes place are processed in real-time, this significant variation being determined by the angular error, from the observer's point of view, and relative to the various points of the terrain, which would be committed if these points were not processed, only the angular error greater than a certain threshold being taken into account.
