Animal ear tag matrix encoding identification method and device

Abstract

The invention discloses an animal ear tag matrix encoding identification method and device, and relates to the technical field of computers. The method comprises the following steps of: obtaining an image of an encoding region of animal tags; carrying out white-black binary processing on the image of the encoding region; determining the number of lines and number of rows of an encoding matrix in the encoding area after the binary processing by utilizing a protection segmentation algorithm; carrying out grid generation on the encoding region according to the determined number of lines and number of rows; and decoding the encoding matrix according to pixel values of pixel points in each grid, and identifying information of animals included in the encoding matrix. According to the method, the images of the encoding region of the animal tags is acquired, and the encoding matrix of the encoding region is divided and decoded by utilizing the projection segmentation method, so that the reading of animal tag matrix codes is realized; and the method is strong in university, is suitable for various devices capable of acquiring and processing images, is simple and convenient to apply, and can carry out real-time decoding to realize decoding during shooting.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a recognition method and device for an animal ear tag matrix code. Background technique [0002] In order to ensure the food safety of meat products such as pigs, cattle, and mutton, supervision has been strengthened from "production-epidemic prevention-quarantine-transportation-slaughter-distribution", led by the China Center for Animal Disease Prevention and Control of the Ministry of Agriculture, to build a nationwide "Animal identification and animal product traceability information system" (hereinafter referred to as: traceability system). The traceability system prints the "anti-counterfeit matrix two-dimensional code" on the ear tag, and each animal wears an ear tag when it is born, and establishes a life-long unique identity mark (ear tag number), which becomes the basis of the entire information traceability system. In order to effectively ensure the smooth operation ...

Problems solved by technology

[0003] However, it should be noted that the anti-counterfeiting matrix code printed on the animal ear tag is very different from the common QRCode, Data Matrix and other two-dimensional codes in shape. Positioning graphics, etc., the existing two-dimensional code machine reading algorithm cannot be used to identify the anti-counterfeiting animal ear tag matrix code
