Abstract

The invention discloses a decoding method of a reader-writer, the reader-writer and a storage medium. The decoding method of the reader-writer comprises the steps that: a first frame of image is shot through a camera, wherein when the camera shoots the exposure moment of the first frame of image, a laser sight is started, so that the first frame of image contains a laser center point emitted by the laser sight; a second frame of image is shot through the camera, wherein when the camera shoots the second frame of image at the exposure moment, the laser sight is turned off, so that the second frame of image does not contain the laser center point, and the time difference of shooting the first frame of image and shooting the second frame of image by the camera is smaller than or equal to a set time threshold value; a first position of a laser center point in the first frame image is determined, and a second position corresponding to the first position in the second frame image is determined; and the bar code at the second position in the second frame image is obtained, and the bar code at the second position is analyzed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a decoding method for a reader-writer, a reader-writer and a storage medium. Background technique [0002] Radio Frequency Identification (RFID) is an automatic identification technology and a key technology for building the Internet of Things. The RFID system is mainly composed of readers and transponders. The transponder is mainly composed of antenna, coupling element and chip. Generally speaking, a tag is used as a transponder. Each tag has a unique electronic product code and is attached to the object to identify the target object. The reader, or reader, is mainly composed of an antenna, a coupling element and a chip. It is a device for reading and / or writing tag information, and can be designed as a mobile handheld device or a fixed device. [0003] The application of RFID technology in various fields, especially in logistics, retail, clothing and other fields, is...
