METHOD FOR NAVIGATION OF MOVING OBJECTS Russian patent published in 2013 - IPC G01C21/30 

FIELD: physics.

SUBSTANCE: reference map is used. A reference object (RO) is selected on said map. A first current map of the RO is obtained. The first current map of the RO is converted to a digital image thereof. The RO is identified on the digital image. The position and spatial parameters of the RO on the digital image are determined. The digital image of the first current and reference maps of the RO are compared by adjusting parameters of the RO on the digital image of the first current map until match with parameters of the RO on the digital image of the reference map. Coordinates of the RO are determined. The first position of the moving objects (MO) in plane coordinates of the reference map is determined. A second current map of the RO is obtained a fixed time interval At after obtaining the first current map of the RO. The second position of the MO in plane coordinates of the reference map is obtained in the same manner as the first position. The direction of movement and speed of the MO are determined. A third current map of the RO is obtained a time interval At after obtaining the second current map of the RO. The third position of the MO in plane coordinates of the reference map is obtained in the same manner as the first position. The direction of movement and speed of the MO are corrected. The acceleration of the MO is determined. A motion path adjustment signal is calculated and movement of the MO is controlled.

EFFECT: broader navigation capabilities.
