Method for identifying storage position of food material in refrigerator and refrigerator

Abstract

The invention relates to the technical field of household appliances, in particular to a method for identifying a storage position of a food material in a refrigerator and the refrigerator. To a certain extent, the problems that depth information of a common color image is missing, the calculation amount of an invalid image area is large, and the storage position of the food material cannot be identified when the position of a refrigerator partition plate is changed can be solved. The method comprises the steps of collecting a first image and a second image of a refrigerator door area; settinga region of interest on the first image to obtain a first ROI, setting a region of interest on the second image to obtain a second ROI, and performing baffle detection based on the second ROI to obtain baffle position information; carrying out detection based on the first ROI to obtain a motion area; carrying out detection in the motion area to obtain a hand centroid motion track; and identifyingand obtaining the storage position of the food material according to the hand centroid motion track and the partition plate position information.

Description

technical field [0001] The present application relates to the technical field of household electrical appliances, in particular to a method for identifying storage and retrieval locations of food items in a refrigerator and a refrigerator. Background technique [0002] Refrigerator, as the most common white goods in family life, is the earliest home appliance product that started and developed among Chinese home appliances. Among them, the food material management of the refrigerator has become the core function of the smart refrigerator, and the food material management includes the management of the type, quantity, freshness period and storage location information of the food material. The food storage location information is used to provide the user with the storage locations of the food in different partitions in the refrigerator. [0003] In the implementation of some methods for identifying the access location of refrigerator ingredients, the types of different ingred...

AI Technical Summary

Problems solved by technology

[0005] This application provides a method for identifying the access location of refrigerator ingredients and a refrigerator, by constructing the first image, the second image, the first ROI, and the second ROI, obtaining the position information of the partition, constructing a confidence heat map, and calculating the background image Templates and detection of the motion trajectory of the center of mass of the hand can solve the problems of lack of depth information in ordinary color images, large calculations in invalid areas of images, and unrecognizable food storage locations when the position of the refrigerator partition changes.
