Food condition tracking method based on spectral images, food management method, and food management device supporting same

A food state tracking method based on a spectral image, the method comprising:

• by a processor of a food management device that manages storage of food,
• establishing a communication channel with a storage warehouse where the food is stored;
• receiving food-related information on the food received in the storage warehouse from the storage warehouse;
• acquiring spectral images of the food at regular intervals by using a spectral camera disposed to capture the spectral images of the food;
• and
• monitoring a change in a state of the food by analyzing the acquired spectral images.

A food management device supporting a food management function based on a spectral image, the device comprising:

• at least one spectral camera for acquiring spectral images of a ripened food received in a storage warehouse;
• and
• a processor functionally connected to the at least one spectral camera,
• the processor configured to:
• when the ripened food is received at a point of the storage warehouse,
• activate a spectral camera disposed to photograph the point of the storage warehouse,
• acquire a spectral image of the ripened food through the activated spectral camera,
• detect a ripening state of the ripened food by comparing the spectral image with a pre-stored reference model, and
• output a message according to the ripening state.

A food management method based on a spectral image, the method comprising:

• receiving food-related information related to storage of a ripened food from a storage warehouse;
• activating a spectral camera disposed to photograph a point of the storage warehouse, based on the food-related information;
• acquiring a spectral image of the ripened food through the activated spectral camera;
• detecting a ripening state of the ripened food by comparing the spectral image with a pre-stored reference model;
• and
• outputting a message according to the ripening state.

A food management device supporting a food management function based on a spectral image, the device comprising:

• a server communication circuit establishing a communication channel with a storage warehouse and a food management device;
• and
• a server processor functionally connected to the server communication circuit,
• the server processor configured to:
• when receiving a message about reception of a ripened food from the storage warehouse, request a spectral image of the ripened food from the food management device that controls the spectral camera disposed at a location where the ripened food is received,
• when receiving the spectral image from the food management device, detect a ripening state of the ripened food by comparing the spectral image with a pre-stored reference model, and
• output a message based on the detected ripening state.
