METHOD FOR BUILDING OUTDOOR MAP FOR MOVING OBJECT AND APPARATUS THEREOF
First Claim
1. A method for building an outdoor map for a moving object, the method comprising:
- receiving a real satellite image for an outdoor space to which the moving object is to move;
calculating pixel information including sizes of length and width pixels and a physical distance of one pixel in the real satellite image;
measuring a reference position coordinate for a reference position selected from the real satellite image; and
linking a pixel number corresponding to the reference position, the reference position coordinate, and the pixel information to the real satellite image in order to build the outdoor map for the moving object.

Abstract
The method for building an outdoor map for a moving object according to an exemplary embodiment of the present invention includes: receiving a real satellite image for an outdoor space to which the moving object is to move; calculating pixel information including sizes of length and width pixels and a physical distance of one pixel in the real satellite image; measuring a reference position coordinate for a reference position selected from the real satellite image; and linking a pixel number corresponding to the reference position, the reference position coordinate, and the pixel information to the real satellite image in order to build the outdoor map for the moving object, and further includes creating information on a road network in which the moving object navigates based on the pixel number corresponding to the reference position, the reference position coordinate, and the pixel information.
