Digital mission preparation system
A system for preparing a mission from a digital mapping, includes a mission editor generating mission elements that can change over the course of several determined temporal phases, including on a network a mission server, a mapping server, a server for sharing at least one centre of the map and a plurality of augmented reality headsets, at least one of the augmented reality headsets, called master headset, being able to generate at least one command for modifying the centre, each headset being able to receive at least two sets of elevation and terrain tiles from the mapping server, the mission server interfacing with the headsets to share and update the mission elements and to change them over time.
1. A mission preparation system for preparing a mission in a determined georeferenced zone from a digital mapping stored in a memory, comprising a digital mission editor in the georeferenced zone generating a set of georeferenced mission elements which are changeable over the course of several determined temporal phases, the mission preparation system comprises in a communication network at least:
a mission server in communication link with the digital mission editor,
a mapping server generating a map from the stored digital mapping,
a sharing server for sharing at least one centre of the map and
a plurality of augmented reality headsets,
at least one of the augmented reality headsets being a master headset and adapted to generate at least one command for at least one modification of the centre of the map, each augmented reality headset being adapted to send a tile request to the mapping server, the tile request comprising the centre of the map, each augmented reality headset being adapted to receive at least two sets of elevation and terrain tiles coming from the mapping server on request of each headset, the mission server being adapted to interface with the mission editor and with the augmented reality headsets to share and update the set of georeferenced mission elements on request of each headset and to make them evolve temporally on request of at least the master headset, the sharing server being adapted to receive, from the master headset, the modification of the centre of the map and to transmit a notification of the modification of the new centre to the augmented reality headsets in order to allow each augmented reality headset to include the modification of the centre of the map in their tile request to the mapping server.
2. The mission preparation system according to claim 1 , wherein each headset comprises a hologram simulation function, by stereoscopic display, the hologram comprising a three-dimensional mapping in which the terrain tiles are placed over a relief constituted by the elevation tiles and superimposing the mission elements at the level of the relief.
3. The mission preparation system according to claim 2 , wherein the hologram simulation function of each headset carries out a three-dimensional hologram calculation in an area at an edge of the displayed hologram, ready to be projected in a fluid manner in the event of modification of the centre of the map.
4. The mission preparation system according to claim 3 , wherein said master headset activates at least one camera for at least partial recognition of a hand of a user of the master headset for actuating functions, proposed in a displayed menu, for at least one translation of the centre of the map.
5. The mission preparation system according to claim 1 , wherein the last centre of the map adjusted by the master headset is taken into account for the tile requests of each headset, transmissions of previous tiles on intermediate modified centres being abandoned.
6. The mission preparation system according to claim 1 , further comprising at least one marker arranged on at least one hardware object around which gather the users of the headsets, an image of said marker being captured by a camera of each headset and processed to carry out an adjustment of the positioning of the centre of the map and an adjustment of the orientation of the map.
7. The mission preparation system according to claim 6 , wherein said hardware object around which gather the users of the headsets is in the form of a table of surface corresponding substantially to the surface on the ground of the displayed hologram.
8. The mission preparation system according to claim 1 , wherein the sharing server also carries out a sharing of at least the position of each headset with respect to the map, and a sharing of the zoom level.
9. The mission preparation system according to claim 1 , wherein the mapping server calculates and stores in a memory, from the digital mapping, a first series of tiles of a first high definition level and at least one second series of tiles of a second lower definition level.
10. The mission preparation system according to claim 1 , wherein each headset comprises a function for detecting its hardware environment.
