Abstract: A method for capturing motion of an object, the method comprising: installing at least one marker on the object; bringing the object having the at least one marker installed thereon in an acquisition volume; arranging at least two event-based light sensors such that respective fields of view of the at least two event-based light sensors cover the acquisition volume, wherein each event-based light sensor has an array of pixels; receiving events asynchronously from the pixels of the at least two event-based light sensors depending on variations of incident light from the at least one marker sensed by the pixels; and processing the events to position the at least one marker within the acquisition volume and capture motion of the object.

Abstract: A method for analyzing recurrent streams of digital data to detect anomalies. The digital data streams are acquired by an explorer having a sensor and processed by a digital data processing center. A knowledge base and a statistical model representing a set of the digital data having same context of obtainment are generated from the stream of digital data acquired by the sensor. Another stream of digital data is acquired by the sensor and the digital data processing center detects anomalies by comparing the statistical model to the statistical data of the other stream of digital data.

Abstract: A system for locating at least one object in a real space by image processing, comprises a computation center (center), with a database of a virtual environment, a virtual representation of the real space, and computing the position of a point from which the virtual environment appears on a real space image obtained by an image acquisition device borne by the object. The center is sited remotely from the object. A data transmission device transfers the image data from the object to the center and the location data from the center to the object. The center processes the image data to determine a position from which the image was acquired, and stores, in a complementary database, data of the processed image to complement and/or to correct an initial database. The locating system implements a locating method for locating and transmitting the location data to a plurality of real environment objects.

Abstract: A method for analyzing geographical regions and detecting areas of interest by a exploration system comprising a sensor and a digital data processing center. The method includes a first phase of learning the intrinsic appearance of each geographical region, in which a database of knowledge comprising groups of digital data is generated. The method further includes a second phase of detecting areas of interest in the geographical regions. The phases includes acquiring a piece of digital data corresponding to a geographical region by the sensor, transmitting the acquired digital data to the digital data processing center, and processing the digital data by the digital data processing center.
