Abstract
Discussed herein is a method of managing product reception/release data of a refrigerator including obtaining internal image data of the refrigerator using a camera provided in the refrigerator, extracting high-reliability data from the internal image data of the refrigerator, updating product reception/release data based on the high-reliability data, and creating a user database based on the updated product reception/release data.
Claims16
A method of managing product reception/release data of a refrigerator, the method comprising:
- obtaining internal image data of the refrigerator using a camera provided in the refrigerator;
- extracting high-reliability data from the internal image data of the refrigerator;
- updating product reception/release data based on the high-reliability data;
- creating a user database based on the updated product reception/release data;
- and
- generating final product reception/release data by removing temporary reception/release data from the updated product reception/release data, via a processor,
- wherein the extracting the high-reliability data from the internal image data of the refrigerator comprises at least removing product covering data,
- wherein the removing of the product covering data comprises:
- detecting a new product region;
- extracting intersection region information of the new product region and an existing product region;
- and
- when intersection region information is larger than a preset value, determining reception/release of an existing product using a similarity between a region other than the intersection region of the existing product region and a region corresponding to the region other than the intersection region of the existing product region before a new product is received, when a size of the new product region is smaller than that of the existing product region, and
- wherein the determining of the reception/release of the existing product using the similarity comprises:
- maintaining a reception status of the existing product when the similarity is larger than a preset value, and
- determining that the existing product is released when the similarity is equal to or less than the preset value.

A refrigerator comprising:
- a communication unit;
- a memory configured to store product reception/release data of at least one product in the refrigerator;
- a camera configured to obtain internal image data of the refrigerator;
- and
- a processor configured to extract high-reliability data from the internal image data of the refrigerator, update the product reception/release data based on the high-reliability data and create a user database based on the updated product reception/release data,
- wherein the processor is further configured to generate final product reception/release data by removing temporary reception/release data from the updated product reception/release data, via a processor,
- wherein the extracting the high-reliability data from the internal image data of the refrigerator comprises at least removing product covering data,
- wherein the removing of the product covering data comprises:
- detecting a new product region;
- extracting intersection region information of the new product region and an existing product region;
- and
- when intersection region information is larger than a preset value, determining reception/release of an existing product using a similarity between a region other than the intersection region of the existing product region and a region corresponding to the region other than the intersection region of the existing product region before a new product is received, when a size of the new product region is smaller than that of the existing product region, and
- wherein the determining of the reception/release of the existing product using the similarity comprises:
- maintaining a reception status of the existing product when the similarity is larger than a preset value, and
- determining that the existing product is released when the similarity is equal to or less than the preset value.
12 more elements
A product reception/release management system comprising:
- a refrigerator;
- and
- a server communicating with the refrigerator,
- wherein the refrigerator comprises a communication unit, a memory configured to store reception/release data, a camera configured to obtain internal image data of the refrigerator;
- and a processor,
- wherein the server comprises:
- a communication unit configured to communicate with the refrigerator;
- and
- a processor configured to obtain the internal image data of the refrigerator through the communication unit and create a user database,
- wherein the processor of the server is configured to extract high-reliability data from the internal image data of the refrigerator, update product reception/release data based on the high-reliability data and create a refrigerator reception/release database based on the updated product reception/release data, and
- wherein the processor is further configured to generate final product reception/release data by removing temporary reception/release data from the updated product reception/release data, via a processor,
- wherein the extracting the high-reliability data from the internal image data of the refrigerator comprises at least removing product covering data,
- wherein the removing of the product covering data comprises:
- detecting a new product region;
- extracting intersection region information of the new product region and an existing product region;
- and
- when intersection region information is larger than a preset value, determining reception/release of an existing product using a similarity between a region other than the intersection region of the existing product region and a region corresponding to the region other than the intersection region of the existing product region before a new product is received, when a size of the new product region is smaller than that of the existing product region, and
- wherein the determining of the reception/release of the existing product using the similarity comprises:
- maintaining a reception status of the existing product when the similarity is larger than a preset value, and
- determining that the existing product is released when the similarity is equal to or less than the preset value.
