Detection system for food in refrigerator and refrigerator

Abstract

The invention provides a detection system for food in a refrigerator and the refrigerator. The detection system for food in the refrigerator comprises a hyperspectral imaging device, a light source device, a detection controller and a type detection device; the hyperspectral imaging device is arranged inside a refrigerator body of the refrigerator, moreover, the shooting angle faces a detection area, the detection area is formed inside the refrigerator body and is used for containing the detected food; the light source device is also arranged inside the refrigerator body of the refrigerator, comprises a halogen tungsten lamp, and is used for providing shooting light for the hyperspectral imaging device by utilizing the halogen tungsten lamp; the detection controller is configured to acquire a type detection trigger signal and start the hyperspectral imaging device and the halogen tungsten lamp according to the trigger signal; and the type detection device is configured to recognize thetype of the detected food by utilizing hyperspectral data shot by the hyperspectral imaging device. According to the scheme, image information and spectral information are comprehensively utilized for carrying out food type recognition, and the recognition accuracy is high; and meanwhile, the halogen tungsten lamp with the wide spectral range is adopted to provide the shooting light, so that theimaging requirements are met.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a food detection system in a refrigerator and a refrigerator. Background technique [0002] With the progress of society and the improvement of people's living standards, consumers not only pay attention to the nutritional value and safety of food when purchasing food, but also consider factors such as price, taste, appearance and freshness, and the role of refrigerators has changed from simply storing The preservation of freshness has gradually transformed into a food management center and a family nutrition center, which also poses new challenges to refrigerators. At the same time, it also provides opportunities for the application of various intelligent identification technologies on refrigerators. The way to understand the types of ingredients stored in the refrigerator has also changed from opening the refrigerator door to actually checking to intelligent recognition. It ha...

Problems solved by technology

The automatic identification technologies currently applied to refrigerators include radio frequency identification and image recognition. Radio frequency identification is to post radio frequency identification codes on the ingredients put in the refrigerator, and use the radio frequency identification device installed on the refrigerator to identify them. This technology requires the purchased ingredients It itself contains a radio frequency identification code, but most of the food currently on the market does not contain a radio frequency identification code, especially vegetables and fruits do not contain an identification code, so this technology is subject to great application restrictions

[0004] Image recognition technology has also been applied to refrigerators, but the correct recognition rate is low. Since this technology mainly relies on the recognition of the color of the food image or the difference in the shape and texture of the food, it is difficult to correctly identify food with similar colors and shapes. , such as oranges and oranges are difficult to distinguish, and the recognition result is citrus, so the correct rate of this technology needs to be further improved
