Embodiment Construction
[0045] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0046] figure 1 It shows that Embodiment 1 of the present invention provides a visual detection method for cooked meat refrigeration time, including:
[0047] S11. Obtain a hyperspectral image of cooked meat to be tested.
[0048] In this step, it should be noted that meat products contain protein, vitamins and minerals that are beneficial to human health, and are favored by consumers because of their delicious taste and convenience. Compared with fresh meat, meat products are usually not easy to deteriorate and have a long shelf life. However, improper storage for a long time can also lead to spoilage and fission, making them inedible. Therefore, for the cooked meat th...

The invention provides a visual detection method for refrigeration time of cooked meat and a device. The method comprises the following steps: acquiring a hyperspectral image of to-be-detected cooked meat; selecting the hyperspectral image, thereby acquiring a preset pixel scope area; calculating an average spectrum value of the acquired preset pixel scope area; calculating the refrigeration time of the to-be-detected cooked meat, outputting and displaying according to the average spectrum value and a preset multi-model consensus-continuous projection support vector regression model. According to the visual detection method for refrigeration time of cooked meat and the device provided by the invention, the detection result is more accurate and the forecast result is more direct, according to the steps of acquiring the hyperspectral image of to-be-detected cooked meat, selecting the hyperspectral image and acquiring the preset pixel scope area, calculating the average spectrum value of the acquired preset pixel scope area, calculating the refrigeration time of the to-be-detected cooked meat, outputting and displaying according to the average spectrum value and the preset multi-model consensus-continuous projection support vector regression model.
Description
technical field [0001] The invention relates to the technical field of food detection, in particular to a method and device for visually detecting the refrigerating time of cooked meat. Background technique [0002] Meat products contain protein, vitamins and minerals that are beneficial to human health, and because of their delicious taste and convenience, they are deeply favored by consumers. Compared with fresh meat, meat products are usually not easy to deteriorate and have a long shelf life. However, improper storage for a long time can also lead to spoilage and fission, making them inedible. Therefore, issues such as the predictable refrigerated days of meat products and the authenticity of shelf life have always been the focus of attention. Judging the storage period of meat spoilage and quickly detecting the refrigerated time of meat products can meet the needs of consumers for quality control and assurance of meat products, and at the same time can provide scientif...
