Now, an explanation of a nail art method performed through the nail art apparatus under the above-mentioned configuration will be given with reference to
As shown in
Of course, before the entire process is carried out, the user's desired nail art materials are selected through the touchscreen.
In the hand imaging step (S1), the user's hand is scanned through the camera or three-dimensional scanner of the nail measurement part so that the hand image having a size of 400×400 and the hand position data are acquired.
Next, three-dimensional mesh modelling is performed using the hand position data acquired in the hand imaging step (S1) to validate the data. A value (height data) of an axis Z of the validated three-dimensional mesh data is corrected to a desired size, and image data cleansing for removing the background from the corrected image is performed to extract the hand. After that, the hand edges are extracted from the extracted hand, and then, a nail candidate group is selected through region matching on hand image database.
After the nail position information has been extracted through the analysis of the selected nail candidate group, the nail images and colors selected by the user are mated to the nail position information, and the mated images are converted into the form using printer attribute information and then transmitted to the printer. According to the transmitted information, the printer allows the nail images to be printed directly on the nails, and otherwise, the printer allows the nail images to be printed on the nail stickers or artificial nails. The nail color information is analyzed through a histogram, and if the selected nail colors are erroneously printed, a warning message is displayed.
The nail art apparatus having the above-mentioned configuration is equipped with a communication module capable of remotely upgrading the nail images being printed through a mobile application or web server and providing the information about the nail art for the user who joins as a member.
