FIELD: physics.SUBSTANCE: method includes selecting, on a reference map, a measurement area with a reference object (RO), plane coordinates and spatial parameters of which are known with the highest accuracy; obtaining a first current map of the RO when moving objects move over the measurement area, which is converted to a digital image of the current map of the RO; recognising the RO, determining the location and spatial parameters thereof; comparing the reference and first current map of the RO by superimposing; determining a first location of the moving object in plane coordinates of the reference map; determining a second location of the moving object in plane coordinates of the reference map; determining the height of the moving object over the reference map by determining mutual displacement over a time ?t of the first and second locations of the moving object in pixels of the digital image of the current map of the reference object in the direction of movement of the moving object. A database installed on the moving object is used to this end. A signal for correcting the position of the moving object is calculated, said signal being used to control movement of the moving object by correcting the location of said object to facilitate navigation.EFFECT: enabling determination of the height of a moving object.10 dwg |
