Method for reaching materials based on RFID

The invention provides a method for reaching materials based on RFID, which comprises the steps of: pasting a target label on target materials, wherein the target label has the attribute information of the materials; pasting a reference label on fixed materials to exactly locate the target materials; installing a fixed type RFID system in a room to monitor the position change of the target materials; and detecting the target materials out of a coverage area with a movable RFID system carried by a robot body. Essentially, the method builds the relationship between objects in physical space and corresponding targets in information space. The method has high location precision, high searching efficiency and good stability, can still effectively locate and search the materials under the complex environment, and has high recognition rate even the target materials are shaded.
