Embodiment 1

[0060] Embodiment 1 of the present application provides a method for detecting the freshness of food in the refrigerator, such as figure 1 as shown, figure 1 It is a flow chart of a method for detecting the freshness of food in a refrigerator provided by the first embodiment of this application. The method includes:

[0061] S101: Obtain hyperspectral image information of food at a position to be detected in the refrigerator;

[0062] In this application, the freshness of the food in the refrigerator can be detected according to the user's preset fixed time period or random time, and the hyperspectral image information of the food can be obtained by using the hyperspectral imaging device.

[0063] S102: Upload the hyperspectral image information carrying the food freshness information to the server, so that the server uses a hyperspectral image processing algorithm to calculate the first shelf life information of the food.

[0064] The hyperspectral image information carryi...

Embodiment 2

[0069] On the basis of Embodiment 1, Embodiment 2 of the present application provides a more specific method for detecting the freshness of food in the refrigerator. This method is suitable for when the food at the position to be detected has a barcode, by using the barcode information, to The client provides another reference. Such as image 3 as shown, image 3 It is a flowchart of a method for detecting the freshness of food in a refrigerator provided in Embodiment 2 of the present application. The method includes:

[0070] S101: Obtain hyperspectral image information of food at a position to be detected in the refrigerator and barcode information of a barcode pasted on the food;

[0071] In this application, the freshness of the food in the refrigerator can be detected according to the user's preset fixed time period or random time, and the hyperspectral image information of the food can be obtained by using the hyperspectral imaging device, and the food pasted on the f...

Embodiment 3

[0089] Embodiment 3 of the present application provides a system for detecting the freshness of food in the refrigerator, such as Figure 5 as shown, Figure 5 It is a schematic structural diagram of a system for detecting the freshness of food in a refrigerator provided in Embodiment 3 of the present application. The system includes: a first acquiring unit 101, an uploading unit 102 and a second acquiring unit 103, wherein,

[0090] The first acquisition unit 101 is configured to acquire hyperspectral image information of food at a position to be detected in the refrigerator;

[0091] An uploading unit 102, configured to upload hyperspectral image information carrying food freshness information to a server;

[0092] The second acquiring unit 103 is configured to enable the server to use a hyperspectral image processing algorithm to calculate the first shelf life information of the food according to the hyperspectral image information.

[0093] Specifically, such as Figur...

Abstract

The invention provides a method and a system for detecting food freshness in a refrigerator, and the method is as follows: acquisition of hyperspectral image information of food in a to-be-detected position in the refrigerator; uploading of the hyperspectral image information containing food freshness information to a server to obtain first shelf life information of the food by use of a hyperspectral image processing algorithm by the server. The first shelf life information of the food can be obtained by the hyperspectral image processing algorithm, so that the food freshness can be determined, the method has high accuracy, the method avoids to misjudge whether food the stored in the refrigerator is fresh only by experience, and unpredictable consequences caused by the misjudgment can be prevented.

Description

technical field [0001] The present application relates to the technical field of refrigerator food preservation, in particular to a method and system for detecting the freshness of food in a refrigerator. Background technique [0002] At present, many foods purchased in the vegetable market, such as meat products, fruits and vegetables, etc., do not have an obvious shelf life. Even the food purchased in the supermarket will have some necrosis, but the user is not easy to detect; with the continuous acceleration of the pace of modern life, many people especially It is because working people seldom pay attention to the specific freshness of food, which will not only cause a waste of resources, but also affect their health, which is directly related to the quality of life. [0003] Considering that the types of food are mainly fruits, vegetables and meat, the maturity of fruits and vegetables and the total number of bacteria on the surface of fresh meat are important indicators...
