Object recognition apparatus

摘要

This invention relates to an object recognition apparatus. This apparatus comprises an antenna (30) which emits transmission beams toward a plurality of directions; a receiving circuit which receives reflected signals of the transmission beams from predetermined directions; a distance and direction calculation circuit (60, 70) which calculates distance and direction to objects reflecting the transmission beams based on the transmission beams and the reflected signals; an object pattern storage unit (80) which stores range direction patterns of reflected signals obtained in advance with respect to predetermined objects; an object recognition circuit (90) which compares range direction patterns of the reflected signals received by the receiving circuit with respect to the predetermined directions, with the range direction patterns stored in the object pattern storage unit (80), and which recognize that a pair of reflected signals from two neighboring directions are signals reflected by the same object.
