Claim 12:
13. A method of performing an inventory of items stored within a storage area using an autonomous vehicle moving within the storage area, the method comprising:
detecting, by a beacon, a position of the autonomous vehicle within the storage area;
measuring, by at least one sensor, an altitude of autonomous vehicle and a distance between the autonomous vehicle and a stack of items stored within the storage area;
calculating, by a processor, a number of items in the stack of items based on the measured altitude, the measured distance and the detected position of the autonomous vehicle;
updating, by the processor, inventory records based on the calculated number of items in the stack; and
determining, by the processor, a complete inventory of a warehouse by a result of the update of the inventory of the storage area,
wherein the number of items is calculated by:
determining a standardized height of a stack associated with the detected position of the autonomous vehicle;
measuring a height of the stack based on the measured altitude and measured distance;
comparing the standardized height of the stack to the measured height of the stack; and
calculating a number of items in the stack only based on a comparison of the standardized height and the measured height.
