Abstract: A method of automatically recognizing and matching artificial signs is discussed, which falls into two parts: a set of artificial sign design with respective characteristics and a method of automatically recognizing and matching the signs. The latter contains several parts: sign recognition, sign demarcation and sign matching. This method is mainly implemented by hardware circuit, also there are some programs in it . It will resolve the problem mentioned above and improve the efficiency of recognizing and matching.
