  • Patent number: 5739789
    Abstract: Method which involves determining the position of a number of measured objects by determining a number of directions to the measured objects from at least two measuring stations, of which at least one is mobile, the method being used to decide which of the points of intersection between the directions correspond to measured objects and which ones do not correspond to measured objects. Changes in the mutual movements between the measuring stations and the points of intersection are in this case determined by comparison between the paths in which the points of intersection and the measuring stations are moving. The points of intersection whose movement is not affected by changes in the movement of other points of intersection, or by changes in the movement of at least one measuring station, correspond to positions of measured objects.
