1. A map building apparatus, including one or more processing devices, the apparatus comprising:
- a base map building unit using the one or more processing devices configured to generate a first map and a second map based on at least two different distances represented by a same output signal of a measurement sensor, the output signal being an output distance measurement indicating signal; and
a final map building unit configured to selectively combine portions of the first map with portions of the second map to create a third map.

Abstract
Disclosed are a map building apparatus and method using a distance measurement. According to an aspect, by creating a first map and a second map respectively using the characteristics of different characteristic areas based on a distance-voltage characteristics of a distance measurement sensor, and combining the first map with the second map, a grid map is created. Accordingly, since a map regarding a peripheral environment is created using plural areas of the distance-voltage characteristics, a more accurate map may be created.

11. A map building apparatus comprising:
-
a base map building unit using the one or more processing devices configured to generate a first map and a second map based on an output distance measurement indicating signal, of a measurement sensor, with the output distance measurement indicating signal representing at least two different distances for a same output signal; and a final map building unit to selectively combine portions of the first map with portions of the second map to create a third map, wherein the first map and the second map overlap.
