Meat freshness detecting method and device

The embodiment of the invention provides a meat freshness detecting method and device. The method comprises the steps that a spectral digital signal of meat to be tested is acquired; the spectral digital signal is input into a meat freshness model to acquire a freshness value of the meat to be tested; and the meat freshness model is acquired by training samples based on the meat spectral digital signal and the corresponding meat freshness value. According to the embodiment of the invention, the spectral digital signal of the meat to be tested is acquired, and the spectral digital signal is input into the meat freshness model to directly acquire the freshness value of the meat to be tested; and the meat freshness can be quickly detected. 本发明实施例提供种肉类新鲜度检测方法及装置。该方法包括：获取待测肉类的光谱数字信号；将光谱数字信号输入肉类新鲜度模型，获得待测肉类的新鲜度值；其中，肉类新鲜度模型是基于肉类光谱数字信号及相应的肉类新鲜度值的样本进行训练后得到的。本发明实施例通过获取待测肉类的光谱数字信号，并将光谱数字信号输入肉类新鲜度模型，直接获得待测肉类的新鲜度值。能够快速实现对肉类的新鲜度的检测。
