The invention provides an object recognition method, which comprises the steps that an electric field signal receiver receives an electric field signal, wherein the electric field signal is transmitted by an electric field signal transmitter on an unknown object by adopting a frequency hopping manner, and the electric field signal passes a channel formed by the body of at least one user in the space transmission process; and the unknown object is recognized according to energy envelope of the electric field signal. The invention further discloses an object recognition device. According to the object recognition method and device provided by the embodiment of the invention, the identity of an object can be recognized accurately only through the energy envelope of the electric field signal, complicated operations are not required, and requirements for the processing capacity of intelligent electronic equipment are reduced.
