A planar article positioning recognition array layer structure disclosed by the present invention comprises an RFID antenna array, a photosensitive array, a temperature sensing array, an array information collection module and an array information processing and analyzing module, and also comprises array control circuits corresponding to the arrays. The array information collection module and the array information processing and analyzing module are connected mutually, and the array control circuits are connected with the array information collection module separately. According to the present invention, the overall structure is placed behind the bottoms of the flat places, such as the wall surfaces, the desktops, etc., so that the articles and the persons with the labels can be positioned accurately, at the same time, the problem when the articles and the persons without the labels occur is solved, and the types of the articles can be distinguished generally by utilizing the temperature sensing array. Meanwhile, the articles are scanned and modeled, the conformity of the articles is compared with a labeled article three-dimensional database, the accurate horizontal coordinates and space coordinates of the articles are confirmed by the secondary verification and can be provided for an execution mechanism to use, thereby avoiding the articles without the labels accurately.
