POSITION DETERMINATION APPARATUS AND METHOD USING VISION SYSTEM

摘要

PURPOSE: A location determination apparatus and method using a vision system are provided to improve continuity and reliability of location determination. CONSTITUTION: A location determination apparatus comprises a satellite navigation system(510), a database(520), a vision system(530), a map matching system(540), and a location calculating part(550). The database stores coordinate data of a plurality of buildings. The map matching system calculates the coordinate data of a second target building recognized through a stereo camera by applying map matching. The vision system extracts coordinate data of a first target building from the database and calculates two first pseudo distances using the coordinate data of the second target building and the coordinate data of the first target building. The location calculating part calculates a second pseudo distance by location data and measures location of a moving body using the two first pseudo distances and the second pseudo distances.
