7. The registration device according to Claim 1, wherein the processor further registers, in the database, classification presence or absence information indicating whether the detailed information is registered in the database in association with the first image data.
8. The registration device according to Claim 1, wherein the first image data is a captured image obtained by imaging the article to be registered by an imaging device communicably connected to the processor.
9. A registration method comprising: acquiring first image data of an article to be registered in the database; calculating similarity of second image data of each of at least one registered article already stored in the database to the first image data of the article to be registered; determining whether there is a registered article of which similarity is equal to or more than a threshold; and when it is determined that there is a registered article of which similarity is equal to or more than the threshold, registering detailed information indicating a detailed classification of the article to be registered in the database in association with the first image data.
10. A recognition device comprising a processor communicably connected to a database in which article information is registered in advance, and configured to perform authentication of an object, wherein the processor is configured to determine whether there is an article similar to the object in the database, when it is determined that there is a similar article similar to the object in the database, determine whether registration information of the similar article stored in the database includes classification presence or absence information indicating whether a detailed classification of the similar article is included, and when it is determined that the classification presence or absence information indicating that the detailed classification is included is included, detect detailed information indicating a feature of the object from a captured image of the object.
11. The recognition device according to Claim 10, wherein the processor is configured to detect, from the captured image of the object, a common region having a design common to image data of the similar article, and detect the detailed information from the captured image of the object based on information on a relative location between the common region and the detailed information, the relative location being included in the registration information of the similar article.
12. The recognition device according to Claim 11, wherein when the detailed information that is detected matches detailed information of the similar article, the processor determines that the object is an article equivalent to the similar article.
13. The recognition device according to Claim 12, wherein when it is determined that there is a plurality of the similar articles similar to the object in the database, the processor determines whether the detailed information that is detected matches the detailed information of the similar article in descending order of similarity between the object and the similar article.
14. A recognition method comprising: determining whether there is an article similar to an object to be authenticated in a database in which article information is registered in advance; when it is determined that there is a similar article similar to the object in the database, determining whether registration information of the similar article stored in the database includes classification presence or absence information indicating whether a detailed classification of the similar article is included; and when it is determined that the classification presence or absence information indicating that the detailed classification is included is included, detecting detailed information indicating a feature of the object from a captured image of the object.
15.

Description

TECHNICAL FIELD The present disclosure relates to a registration device, a registration method, a recognition device, a recognition method, and a program. BACKGROUND ART Patent Literature 1 discloses an online shopping system including an image DB that stores product images, and a product information DB that stores size information and a stock status for each size category of product in association with a product image stored in the image DB. The online shopping system includes an image determination unit that extracts an image that matches a product image stored in the image DB based on a received product image, and extracts, with reference to the product information DB, product information associated with the image. The online shopping system further includes a conforming size determination unit that compares the size of the product extracted by the image determination unit with the size of a customer to determine a size category of the product conforming to the customer, and an information transmission unit that transmits the product information extracted by the image determination unit, the size category determined by the conforming size determination unit, and the stock status to a mobile terminal. Citation List Patent Literature PTL 1: Unexamined Japanese Patent Publication No. 2009-294909 SUMMARY OF THE INVENTION In Patent Literature 1, the online shopping system stores, in a database, image data of a product in association with a product ID. Furthermore, the online shopping system can register the image data in association with the information related to the product by associating the product ID with the information related to the product. However, when the database includes a previously registered product having very similar outer appearances, recognizing an object based on the database may result in erroneously recognizing the object as a different one. An example of products having very similar outer appearances are, for example, shampoo products and treatment products having the same design. The present disclosure has been devised in view of the above-described conventional situation, and an object of the present disclosure is to assist in highly accurate identification of an object. The present disclosure provides a registration device including a processor that performs a registration process of an article, and a database that stores information on the article, wherein the processor is configured to acquire first image data of an article to be registered in the database, calculate similarity of second image data of each of at least one registered article already stored in the database to the first image data of the article to be registered, determine whether there is a registered article of which similarity is equal to or more than a threshold, and when it is determined that there is a registered article of which similarity is equal to or more than the threshold, register detailed information indicating a detailed classification of the article to be registered in the database in association with the first image data. Furthermore, the present disclosure provides a registration method including acquiring first image data of an article to be registered in the database, calculating similarity of second image data of each of at least one registered article already stored in the database to the first image data of the article to be registered, determining whether there is a registered article of which similarity is equal to or more than a threshold, and when it is determined that there is a registered article of which similarity is equal to or more than the threshold, registering detailed information indicating a detailed classification of the article to be registered in the database in association with the first image data. Furthermore, the present disclosure provides a recognition device including a processor communicably connected to a database in which article information is registered in advance, and configured to perform authentication of an object, wherein the processor is configured to determine whether there is an article similar to the object in the database, when it is determined that there is a similar article similar to the object in the database, determine whether registration information of the similar article stored in the database includes classification presence or absence information indicating whether a detailed classification of the similar article is included, and when it is determined that the classification presence or absence information indicating that the detailed classification is included is included, detect detailed information indicating a feature of the object from a captured image of the object. Furthermore, the present disclosure provides a recognition method including determining whether there is an article similar to an object to be authenticated in a database in which article information is registered in advance, when it is determined that there is a similar arti
