Map information comparing and auxiliary positioning system and method thereof

A map information comparing and auxiliary positioning system, disposed on a mobile platform, and comprising:

• an original map establishing module, applied for establishing an original map information marked with a plurality of original positioning reference coordinates standing for a plurality of original feature objects;
• a real-time map establishing module, applied for establishing a real-time map information marked with a plurality of real-time positioning reference coordinates standing for a plurality of real-time feature objects;
• a comparing module, electrically coupled with the original map establishing module and the real-time map establishing module, applied for receiving the original map information and the real-time map information, for comparing the plurality of original positioning reference coordinates with the plurality of real-time positioning reference coordinates, and for defining at least one of the plurality of original positioning reference coordinates the same as one of the plurality of real-time positioning reference coordinates to be at least one valid reference coordinate;
• and
• a positioning module, electrically coupled with the comparing module and the real-time map establishing module, applied for receiving the at least one valid reference coordinate, and for utilizing the at least one valid reference coordinate to auxiliary position a current position coordinate of the mobile platform in the real-time map information.
