Abstract

The invention relates to the field of spectral imaging technology, and is a fast and non-destructive prediction device for the validity period of fresh pork based on multi-spectral imaging. The problem of damage. The invention collects the diffusion spectrum image of the predicted meat product, extracts information from the collected image, and predicts the validity period of the meat product according to the validity period prediction model established based on the corresponding physical and chemical characteristics of the predicted meat product. The invention can predict the expiration date of more than one meat product every second, the accuracy is greater than 90%, and the meat product has no damage.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a device for fast and non-destructive prediction of the expiration date of fresh pork based on multi-spectral imaging. Background technique [0002] In recent years, spectral imaging technology has attracted more and more people's attention, and its application in the quality and safety inspection of agricultural products has become more and more extensive. For example, multi-spectral imaging technology is used to detect the firmness of apples, and multi-hyperspectral imaging technology is used to evaluate beef marbling, thereby grading the quality of beef. However, at present in China, this technology is seldom applied to production sites with systematic or random interference and noise, and the requirements for detection speed and no damage to products after detection are not high. At the same time, in China, there is no clear standard to quantify the validity period ...
