In modern life, with the continuous development of science and technology and the improvement of life quality, people have higher and higher pursuit of aesthetic quality, and therefore, the demand of nail beauty is increased. Nail art is also called nail art design, which is a work of decorating and beautifying nail (toe). The nail art is a process of sterilizing, cleaning, nursing, maintaining, decorating and beautifying nail according to the hand shape, nail shape, skin and clothes color and requirements of guests, and has the characteristic of diversified representation forms. The pattern drawing on the fingernail and toenail or artificial nail paster or sticker is the main function of nail machine, the nail machine is usually composed of computer or microprocessor, printer, display, etc. the pattern used by nail machine is stored in the computer hard disk or other memory called by computer and microprocessor, the pattern is displayed on the display for user to watch and select, and the function of printing nail pattern is realized through the control of relevant software. Usually, thousands or even tens of thousands of nail art patterns with different shapes and types are stored in the nail art to meet different aesthetic requirements of pursuing individuation of users. The user's needs are endless, which requires the pattern designer of the manicure machine to continually provide new patterns for the user to select. Each independent pattern is designed according to the shape of a fingernail, a toenail or an artificial nail patch of a human body according to a certain proportion, position and size, after a user can select the pattern through a display device, a camera device of the nail beautifying machine shoots a nail picture in multiple angles, then the three-dimensional shape of the nail is calculated, the pattern is sprayed on the nail according to the three-dimensional shape of the nail, and the pattern can be correspondingly printed on the fingernail, the toenail or the artificial nail patch or sticker. Such nail art application has the following disadvantages: changeable beautiful first pattern of modelling is that the user pursues all the time, just provides multiple type pattern as far as possible for satisfying user's demand, perhaps designs out the series pattern that has certain combinatorial significance, and user's demand is big more, and the pattern is more, and the design volume is big more, and the loaded down with trivial details consuming time of manufacture process, and occupy a large amount of storage space, and current digital nail machine price is more expensive moreover, and the volume ratio is bigger, only uses in professional beautiful first shop. Therefore, the deficiencies of the current technology include the following:

firstly, the picture processing mode of the application APP on the current intelligent terminal cannot help the user to take pictures conveniently and intuitively, and an ideal design effect is obtained, and is embodied as follows: 1. background pictures are inconvenient to select, the process of drawing each finger is complex, and the flexibility is poor; 2. the selected pictures are inconvenient to be amplified, reduced and rotated and can not be independently applied to a single nail area; 3. it is not easy to lock single or multiple finger patterns; 4. layers or other patterns, characters and the like cannot be intuitively superposed on the background picture;

secondly, processing and outputting the image data obtained by what you see is, the pattern designed in the picture processing APP can have deviation such as scaling, rotation angle and incorrect intercepting area when being output to a nail printer;

and thirdly, automatically distributing online orders, wherein the cloud-based nail art printing orders cannot be automatically distributed to corresponding entity stores to complete printing tasks according to the unit taking position selected by the customer when placing the order.
