Embodiment 1

[0085] A method for generating and verifying a food safety spectral code is provided, and the steps are as follows:

[0086] Step 1: The first spectral scanning machine 31 performs spectral imaging on the food sample to obtain a spectral image.

[0087] For example: as shown in Figure 6(a), taking a ginseng sample as an example, the data format of the hyperspectral image data obtained can be tiff (Tag Image File Format, tag image file format) or other high-bit color image formats.

[0088] Step 2: The data processor 32 extracts the characteristic bands and characteristic spectral data in the spectral image obtained by the first spectral scanning machine 31, and obtains fingerprint data according to the characteristic bands and characteristic spectral data.

[0089] For example: taking a ginseng sample as an example, using the Harris corner detection method, SIFT (Scale-invariant FeatureTransform, scale-invariant feature transformation) algorithm, Surf (Speed ​​Up Robust Featur...

Abstract

The invention discloses a method, a device and a system for generating and verifying a food safety spectrum code. The method comprises the following steps: performing spectral imaging on a food sample to obtain a spectral image; obtaining fingerprint spectrum data according to the spectral data of the spectral image; and according to the fingerprint spectrum data, obtaining a safe spectrum code corresponding to the food sample through visualization processing. According to the invention, the fingerprint spectrum data generated according to the spectrum data corresponding to the spectrum image of the food and the attribute information of the food are jointly used as the basis of the safety spectrum code, the safety spectrum code digitalizes the spectrum image information of the food, and a unique specific fingerprint spectrum is established, so that the food traceability is rigorous, and therefore, fake and counterfeit market counterfeiting phenomena are effectively avoided.

Description

technical field [0001] The invention relates to a method, device and system for generating and verifying a food safety spectral code, belonging to the field of food safety traceability. Background technique [0002] Food traceability is an important part of the food safety traceability system. It is not only conducive to the implementation of origin protection and ensuring fair competition, but more importantly, it can accurately and timely find the source of food safety problems, and it is necessary to take effective measures to control the problem. It provides an important basis for expanding, effectively recalling products, and withdrawing and destroying products. [0003] At present, the two-dimensional code generation process used in food traceability is only directly generated according to the data information of the product name, manufacturer and supplier of the food, which makes the two-dimensional code information easy to be forged and imitated, and can be pasted on...
