Abstract: The present invention relates to a method for exchanging data between drones of a drone swarm comprising at least four drones, the method comprising:



emitting, by each drone, a signal comprising data to be emitted comprising the identifier of the drone, the direction and the identifier of each signal received at the preceding moment by the drone,
receiving, by a drone, called receiver drone, the signal emitted by another drone of the swarm,
determining, by the receiver drone, the direction of each received signal, and
determining, by the receiver drone, for each received signal, the relative position of the drone corresponding to the identifier of the received signal.

Abstract: An airborne optronic equipment item comprises: at least one image sensor suitable for acquiring a plurality of images of a region flown over by a carrier of the equipment item; and a data processor configured or programmed to receive at least one acquired image and transmit it to a display device; wherein the data processor is also configured or programmed to: access a database of images of the region flown over; extract from the database information to synthesize a virtual image of the region which would be seen by an observer situated at a predefined observation point and looking, with a predefined field of view, along a predefined line of sight; synthesize the virtual image; and transmit it to a display device. A method for using such an equipment item is provided.

Abstract: A system for acquiring images in color and near-infrared, comprising: a matrix sensor, which comprises first, second, and third types of pixels sensitive to respective visible colors and a fourth type of panchromatic pixels sensitive in the near-infrared; and a signal processing circuit configured to reconstruct first and second sets of monochromatic images, a panchromatic image, a color image from the images of the first set and from the panchromatic image, and at least one image in the near-infrared from the images of the second set and from the panchromatic image. A visible-near-infrared bispectral camera comprises such an acquisition system and method implemented by means of such a camera.

Abstract: A fuze for detecting an obstacle in proximity, an obstacle in proximity defined as being an obstacle exhibiting a minimum distance from the fuze, wherein the fuze comprises at least: an emission device emitting a light beam directed forward of the fuze; a reception device detecting the luminous fluxes in a cone directed forward of the fuze, the light beam and the cone having relative orientations such that they cross one another; a detection volume being the volume where the light beam crosses the cone so that when an obstacle is in the detection volume, the light emitted by the emission device is backscattered toward the detection device, an obstacle in proximity being detected by detecting the maximum of backscattered power, the reception cone is centered on the axis of the fuze.

Abstract: The present invention relates to a method for assisting in the detection of elements in an environment, comprising:



the acquisition of a first wide-field image of an environment by a first sensor (14A) having a first field of view and a first resolution,
the generation of a fused image from first narrow-field images of the environment acquired by a second sensor (14B) having a second field of view strictly less than the first field of view and a second resolution finer than the first resolution,
In response to the detection of a difference relating to an element on a second wide-field image acquired by the first sensor (14A), compared to the first wide-field image, the acquisition of a second narrow-field image imaging the difference, and
the update the fused image with the second narrow-field image.

Abstract: The present invention relates to an optical pulse detection device, the device comprising a sensor having a plurality of pixels, each pixel comprising:



a receiver configured to receive optical pulses and generate an electrical signal,
an event detection unit comprising a frequency filter having an adjustable cut-off frequency defining a passband for the event detection unit, the adjustable cut-off frequency being such that the upper bound of the passband is greater than or equal to 1 Megahertz, the detection unit being configured to detect variations in the electrical signal generated by the receiver only when the frequency in the frequency domain of said variations is within the passband of the event detection unit, and
a timing unit configured to date each change in the electrical signal detected by the event detection unit.
