Abstract
A device, system, and method for generating location and path-map data for displaying a location and path-map is disclosed. The device includes a first set of sensors for generating a plurality of first data signals with respect to an attitude of an object; a second set of sensors for generating a plurality of second data signals with respect to the attitude of the object; an imaging device for generating a plurality of third data signals that include a most significant feature, which is disposed in at least two images of the imaging device; and at least one processing device that is adapted to calculate a heading direction (bearing) of the device using the plurality of first data signals and the plurality of second data signals; to calculate a distance traveled along the heading direction using the plurality of third data signals; and to translate the calculated heading direction and calculated distance traveled into a leg or portion of a leg of a path-map for visual display on a two- or three-dimensional system.
