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

Abstract

The invention discloses a coding and recognition method and device based on fruit streak map information, and the method comprises the steps: A, clamping and rotating a fruit, and respectively takingan image of a pedicel part and a navel part of each to-be-coded fruit; b, respectively converting the pedicel part image and the navel part image into a pedicel part rectangular image and a navel partrectangular image; c, respectively extracting the features of the pedicel part rectangular image and the navel part rectangular image to form a feature coding table; and D, performing image feature encoding on the fruit to be identified, and matching the obtained feature encoding table with the stored feature encoding table for identifying the feature information of the fruit streak map. According to the coding and recognition method and device based on the fruit streak map information, feature codes are formed based on natural streaks of fruits, and the method and device have the advantagesof being high in precision, tamper-proof and the like.

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...
