Localization system with a cooperative optronic beacon

A localization system including a cooperative optronic beacon, an observation device, and a communication system configured to exchange information between the cooperative optronic beacon and the observation device, said cooperative optronic beacon including a visualization device, the visualization device including a surface of visualization on which is disposed a visualized-orientated-segment of straight line, the surface of visualization having a visualization center, an orthonormal coordinate system whose center is the visualization center, the orthonormal coordinate system having 3 axis, a first axis being perpendicular to the surface of visualization, a second axis which is the visualized-orientated-segment of straight line disposed on the surface of visualization, a third axis being perpendicular to the 2 previous axis, a direction sensor whose optical center is superimposed with the visualization center of the surface of visualization, a first visual identification code defined by a set of specific points which is used for recognition and identification by the observation device of the set of specific points allowing thus the determination of the direction of the optical center of the direction sensor of the visualization device, said direction being an inter-cameras straight line viewed from the observation device, the observation device including an observation camera having an observation optical center, a second visual identification code for recognition and identification by the visualization device, the second visual identification code allowing the determination of the direction of the optical center of the observation camera of the observation device by the visualization device, said direction being the inter-cameras straight line viewed from the visualization device,

• wherein the knowledge by the visualization device of the inter-cameras straight line and of the visualized-orientated-segment of straight line allows the visualization device to deduct a visualized-plane as well as a visualized-transition matrix built from an unitary inter-cameras vector associated to said inter-cameras straight line and from an unitary visualized vector associated to the visualized-orientated-segment of straight line, said visualized-transition matrix allowing to determine an orthonormal coordinate system of the visualized-plane in reference to the orthonormal coordinate system of the visualization device.
