Food recognition system based on intelligent refrigerator

Abstract

The invention discloses a food recognition system based on an intelligent refrigerator, and relates to the field of intelligent refrigerators. The system comprises a controller, a gesture recognitionunit, an image recognition unit, an acquisition unit and a storage unit, wherein the gesture recognition unit, the image recognition unit, the acquisition unit and the storage unit are connected withthe controller; the posture recognition unit is used for judging the posture of a user for accessing food; the image recognition unit is used for recognizing the type and the number of foods accessedby the user; the acquisition unit comprises an infrared sensor 1, an infrared sensor 2, a liquid crystal touch screen and a CDD camera, wherein the infrared sensor 1 and the infrared sensor 2 are arranged on the front frame and the rear frame of the inner wall of a refrigerator door body correspondingly, the liquid crystal touch screen is embedded on the outer wall of the refrigerator door body, and the CDD camera is arranged on the top of a refrigerator body; and the controller is used for acquiring the real-time posture of the current user from the posture recognition unit, acquiring the type and the number of foods accessed by the user from the image recognition unit, performing processing to obtain the information of the refrigerator foods and displaying the information on the liquid crystal touch screen. The system reduces the production cost of the intelligent refrigerator and improves the accuracy rate of food recognition.

Description

technical field [0001] The invention belongs to the field of smart refrigerators, in particular to a food recognition system based on smart refrigerators. Background technique [0002] With the progress of the times, we have more and more requirements for various items we use, and household appliances accompany our daily life. A large part of the quality of life depends on the degree of intelligence of household appliances. Household appliances Smart appliances are an inevitable trend. The intelligence of home appliances is household appliances + artificial intelligence, and refrigerators, as household appliances closely related to our health, are of course the most necessary for intelligent improvement. Moreover, the current refrigerators require us to actively use it. [0003] However, the refrigerators with image recognition function appearing on the market at present, due to factors such as the angle of view of the camera and the occlusion of the shelves in the refrige...

Problems solved by technology

[0004] The purpose of the present invention is to provide a food recognition system based on a smart refrigerator, which can determine whether the user is storing or taking food by installing infrared sensors on the front and rear sides of the refrigerator door, and then check the access control through the camera installed on the outer wall of the refrigerator. The food in the refrigerator is dynamically identified, and finally the food information in the refrigerator is displayed in real time through the LCD display, which solves the problems that the existing refrigerator identification is prone to shooting dead angles, the cost increase caused by too many cameras, and the food identification is not accurate enough
