METHOD AND SYSTEM OF POSITIONING GROUP OF SUBMARINE OBJECTS IN LIMITED WATER VOLUME Russian patent published in 2017 - IPC G01S5/18 

FIELD: physics.

SUBSTANCE: optical beacons are installed on each of the objects, the number of which and their locations on the underwater object are chosen from the condition of ensuring continuous monitoring of, at least, two video cameras. The radiation of optical beacons of the objects are fixed by using four video cameras located at the ends of mutually perpendicular axial lines of the horizontal section of the controlled volume. Initiation of optical beacon radiation is carried out by means of a signal radiated by four initiator-initiators in the optical wave band, the duration of which is equal to the duration of the video frame Δt, the repetition period of which is T=Δt*(N+1), where N - the number of objects in the group, and the beginning of the radiation is synchronized with the camera synchronization pulses. As an identifying feature of the object, a preset video frame number is used, in which the optical beacon of this object emits a signal. Video sequences are allocated in the video frames corresponding to each identified object, by which the coordinates and parameters of the movement of each object are calculated. The processing of video information from video cameras is performed on a computer complex located at the control point for the actions of underwater objects outside the controlled water volume.

EFFECT: identification and continuous determination of coordinates and parameters of the motion group of underwater objects, including partial overlapping of objects.
