A coding and recognition method and device based on fruit pattern information

Abstract

The invention discloses a coding and identification method and device based on fruit grain map information. The method includes steps: A. Clamping and rotating the fruit, and taking a fruit pedicle and a fruit navel of each fruit to be coded respectively. B, convert the fruit pedicle part image and the fruit navel part image into the fruit pedicle part rectangle image and the fruit navel part rectangle image respectively; C, extract the fruit pedicle part rectangle image and the fruit navel part rectangle image feature respectively to form a feature encoding table D. Carry out image feature encoding on the fruit to be identified, and match the obtained feature encoding table with the stored feature encoding table to identify the feature information of the fruit pattern map. The coding and identification method and device based on the fruit texture map information of the present invention forms a characteristic code based on the natural texture of the fruit, and has the advantages of high precision and tamper-proof.

Description

technical field [0001] The invention relates to plant feature extraction and recognition technology, in particular to information coding and recognition technology based on natural fruit texture. Background technique [0002] Establishing a whole-process quality and safety traceability system "from the field to the dining table" has become an urgent need to ensure the "safety on the tip of the tongue" of the public. Individual or batch identification is the basis for traceability, and the existing identification methods are mostly based on barcode or radio frequency identification (RFID) technology. [0003] Barcode technology has powerful functions, for example, the input method has the characteristics of fast speed, high accuracy, and strong reliability. It has been widely used in the fields of commodity circulation, industrial production, warehouse management, and information services. One-dimensional barcodes usually only identify the category of the item, but cannot de...

Problems solved by technology

[0005] In order to solve the problems in the prior art for plant varieties such as fruits, if barcode information is added for coding, identification and traceability, there will be various difficulties. For example, due to the irregular shape of the fruit itself, the barcode or RFID label is easy to fall off, and the fruit The irregular surface is not conducive to the reading of the barcode; in addition, the labeling on the surface of the fruit is easy to pollute the fruit skin, affect the quality of the fruit, and easily cause quality and safety problems; in addition, the labeling of a single fruit not only increases the cost of consumables such as labels, but also Increased labor costs; in addition, there may be forgery and duplication of barcodes, and the same barcode information does not necessarily mean the same fruit, thus reducing the reliability of barcode information and other technical problems
