Method for identifying types of food materials in refrigerator and refrigerator

Abstract

The invention provides a method for identifying types of food materials in a refrigerator and the refrigerator. A hyperspectral imaging device is arranged in a storage chamber of the refrigerator. Themethod for identifying the types of the food materials in the refrigerator comprises the steps that hyperspectral data, shot by the hyperspectral imaging device, of the food materials are obtained; image data and spectral data are correspondingly extracted from the hyperspectral data; and the types of the food materials are identified according to the extracted image data and / or spectral data. The identifying accuracy is remarkably improved, and the user can manage the food materials conveniently.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a method for identifying food types in a refrigerator and a refrigerator. Background technique [0002] With the progress of society and the improvement of people's living standards, consumers sometimes need to know the types of ingredients in the refrigerator without opening the door, or remotely know the types of ingredients in the refrigerator. It has become the development trend of intelligent refrigerators to realize the food type identification function on household refrigerators by using automatic identification technology. [0003] Automatic identification technology is a technology that uses a specific identification device to bring the identified item close to the identification device, automatically obtains the relevant information of the identified item, and provides it to the computer processing system to complete the relevant follow-up processing. The automatic ide...

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

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. identify
