Abstract

The invention discloses an ultrahigh frequency tag reading device having an image recognition function. The ultrahigh frequency tag reading device comprises an industrial control computer, an embeddedGPU, an embedded CPU, an ultrahigh frequency driving module, ultrahigh frequency antennae, a communication module and an image acquisition module. The industrial control computer is connected with the communication module, the communication module is connected with the embedded GPU and the embedded CPU, the image acquisition module is connected with the embedded GPU, the ultrahigh frequency driving module is connected with the embedded CPU, the ultrahigh frequency driving module is connected with the ultrahigh frequency antennae, and a plurality of ultrahigh frequency antennae are arranged. By employing the image recognition mode, the problem that when a bar code is stained or sheltered and an ultrahigh frequency RFID tag is damaged, the luggage cannot be recognized is solved. By employing the image recognition technology, the luggage contour in the image can be recognized quickly, feature points are extracted and compared with a luggage image library stored in the system in real time, and the aim of luggage recognition is achieved.

Description

technical field [0001] The invention relates to the field of logistics, in particular to an ultra-high frequency tag reading device with image recognition function and a recognition method thereof. Background technique [0002] Airport baggage handling systems (BHS systems) usually use one-dimensional barcodes or UHF electronic tags as baggage identification. There are multiple transmission branches on the baggage handling system transmission line, and a set of equipment that can automatically identify baggage tags is required. Recognize the baggage tag, and the baggage handling system will send the baggage to the corresponding location according to the identification of each piece of baggage. One-dimensional barcode is used as the identification label, and the identification rate is 90%. UHF electronic tags are used as identification tags, and the identification rate is 98%. Although the recognition rate of UHF electronic tags is 98%, for an airport that handles tens of t...
