Description of the Related Art Conventionally, a nail print device that is a printing device that prints a design image such as a color or a pattern on the surface of a fingernail of a human finger is known (Patent Document 1). You can easily enjoy nail art without using. However, it is difficult to peel off when the nail parts are securely attached to their fingers, and using the release agent many times hurts the nails. Also, since it is not fashionable to continue using the same nail art for a long time, it is desirable to use different nail art depending on the TPO. Then, the artificial nail composition which can be easily peeled from the nail | claw of a hand or a foot, and the removal method of it are proposed (patent document 2).

Special table 2003-534083 gazette JP 2014-204775 A

  However, with the conventional removal method, the removal agent tends to adversely affect the nail surface, and it is difficult to frequently change the design of the nail art by yourself. Therefore, under the present circumstances, it is usual to change the design of the nail art while protecting the nail surface that is applied at a nail salon etc., and in order to make the change of the design of the nail art easy, a method that does not hurt the nail It is desirable to provide

  In addition, if customers want to decorate their designs with their favorite designs at home, without having to go to the nail salon many times, after the nail print, the user can arrange the parts themselves. You need to think and paste, and if you try to make such a decoration yourself, you do not know where to paste the part or you cannot determine what part to select and paste So, if you want to reproduce nail art while looking at a sample such as a photograph, you had to place the parts on your nail while comparing it with the sample, but for nails that have no mark It is difficult to attach decorative parts such as rhinestones at the same position as the sample.

  The present invention has been made in view of the circumstances as described above, and in order that anyone can easily enjoy decorated nail art, the parts are matched with the parts based on 3D nail art modeling information from the user.

  Hereinafter, an embodiment of a 3D nail art moding method according to the present invention will be described with reference to the accompanying drawings. The embodiments described below are given various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

(A) Acquisition of 3D nail art modeling information Generally, the process from inputting raw 3D shape data of a subject (nail image) with a 3D scanner to creating a complete artificial nail part that can be processed with mechanical CAD is generally 1. Shape input with a 3D scanner, 2. Acquisition of 3D point cloud data, 3. Alignment of 3D point cloud data from multiple viewpoints 4. Meshing of acquired 3D point cloud data; Created by the procedure of creating a parametric solid model. This process is performed using Kinect (a Microsoft human interface device from the US) to obtain a 3D point cloud representing a 3D shape, and the 3D point cloud described above is processed using the open source software library called PCL (Point Cloud Library). The point cloud is processed and finally a three-dimensional model is generated. Details are as follows.

  When Kinect is used as a 3D scanner, 3D point cloud data can be acquired from a color image and a depth image. At this time, the horizontal and vertical positions in the real space are obtained by a trigonometric function. Further, since the acquisition range of the color image and the depth image is different, the three-dimensional point cloud data acquires only the portion covered by the acquisition range of the depth image and the color image. In the three-dimensional point group processing, for example, PCL is used. Here, noise is removed by outlier filtering, the number of data is reduced by voxel grid filtering, and the subsequent processing is accelerated by downsampling. Next, three-dimensional point cloud data that has been filtered is prepared, and after positioning, for example, the initial positioning is performed by SAC-IA to reduce the distance between corresponding points, and the ICP algorithm is used for highly accurate positioning. Align. Hereinafter, using Kinect and PCL, three-dimensional point cloud data viewed from a plurality of viewpoints is acquired and integrated.

Shape input by 1.3D scanner Kinect is used as a non-contact type three-dimensional measuring apparatus. As shown in FIG. 1, Kinect is a 3D scanner 1 having an RGB camera 2 and a depth sensor 3 together with a microphone, which is commercialized by Microsoft. The color image and depth image acquired by Kinect are aligned and converted to three-dimensional point cloud data. The depth image obtained from the shape of the three-dimensional object is converted into three-dimensional coordinates in the real space, and the depth image and the color image are integrated.

2. Conversion from Depth Image to 3D Point Cloud Data The output of the Kinect depth sensor is image data, that is, a depth image. The Kinect depth image is 640 × 480 pixels, and each pixel has a precision of 13 bits. The numerical value of the pixel represents oil and fat placed from the depth sensor to the subject surface in mm units. Each pixel of the image data corresponds to one point on the subject. Accordingly, coordinate values in the horizontal direction (X axis), the vertical direction (Y axis), and the depth direction (Z axis) are calculated in a three-dimensional coordinate system centered on the depth sensor. Among these, the numerical value of the pixel corresponds to the value of the Z axis. The coordinate values of the X axis and the Y axis are obtained from the image coordinates, the viewing angle and the depth (Z value) of the depth sensor. The depth from the subject to the sensor is obtained from the Kinect depth sensor. The horizontal and vertical position from the sensor to the subject is acquired in units of pixels. From the coordinates in pixel units, the viewing angle and distance of Kinect, the actual size of the horizontal and vertical positions is obtained using a trigonometric function.

3. Alignment of Color Image and Depth Image As shown in Kinect in FIG. 1, since the mounting positions of the RGB camera 2 and the depth sensor 3 are shifted, the acquired data is shifted due to parallax. Therefore, it is necessary to match the corresponding coordinate positions.

  The above-described acquisition of a plurality of three-dimensional point group data is performed in the step using Kinect shown in FIG. 2A, and the integration of the plurality of point group data is performed in the step of PCL shown in FIG. 2B. When integrating a plurality of pieces of imaging data such as left, center, and right when the subject is a finger that applies an artificial nail, it is necessary to process an overlapping portion of the imaging data as shown in FIG. 2C.

Next, processing of 3D point cloud data by PCL will be described.
Processing of 3D point cloud data by PCL in FIG. 2B performs the following processing.
1. PCL is an abbreviation for Point Cloud Library, and is open source software that can handle 3D point cloud data. Data acquired by Kinect is processed by PCL, but the acquired data is converted to pcd format and handled by PCL.
2. An outlier filter is to remove a point that retains a certain error.
3. When the density of the voxel grid filter point group may be lowered, filtering is performed.
4). The three-dimensional data obtained by a single measurement with the initial alignment Kinect only represents the shape of a part of the measurement object. In order to acquire complete three-dimensional data of a three-dimensional object, it is necessary to integrate a plurality of viewpoints, preferably three-dimensional point cloud data acquired from the left and right. However, when a plurality of point cloud data are acquired independently, their positional relationship cannot be known. Therefore, alignment is performed in the following order.
(1) Initial alignment is performed by SAC-IA (Sample Consensus Initial Alignment).
(2) High-precision alignment between three-dimensional point cloud data using the ICP algorithm (3) The double wall of the overlapping portion is eliminated by the MLS (Moving Least Squares) algorithm.
(4) Meshing with point cloud data representing 3D shape by GPT (Greedy projection Triangulation) (5) Combining 3D point cloud data viewed from multiple viewpoints to complete a 3D model.

(B) Creation of artificial nail parts In the nail art in the present invention, as shown in the business model diagram shown in FIG. 2D, the user acquires the shape input of the subject with a 3D scanner at a Kinect imaging place (photographer) in his home or town. The photographer creates 3D model data, displays it on the screen, confirms it, sends this data to the data processor (PCL processor), and manually corrects the part that has not been processed by the PCL processing. Have the 3D model data corrected. A network is constructed so that the 3D model data is transmitted to a 3D model user (nail art company) such as an order-made artificial nail supplier. Accordingly, in the 3D shooting room of the town photographer, one or a plurality of 3D scanners 10 are provided to shoot the right and left sides of the subject to shoot the 3D shape data of the subject as shown in FIG. 2C. The shape input acquired by each 3D scanner is combined using PCL. This is transmitted to the processor, and the correction of the part that has not been processed by the PCL is performed manually. After acquiring 3D point cloud data, aligning 3D point cloud data from multiple viewpoints, meshing the acquired 3D point cloud data and correcting the parametric solid model data, This is transmitted to the user, and finally the supplier creates an artificial nail part based on the 3D data.

(C1) Adhesive nail pre-treatment In this example, the pre-decoration artificial nail is pre-treated with the following nail-off liquid and fixed with a double-sided tape or a vacuum pad.

(Adjustment of nail-off liquid)
<Isolation and preparation of aggrecan>
Aggrecan is a kind of proteoglucan and was isolated and prepared as follows.
Salmon nasal cartilage was sliced, 0.1% citric acid aqueous solution of about 10 times the salmon cartilage tissue was added, and aggrecan was extracted by immersion for 24 hours at room temperature. Thereafter, the immersion liquid containing salmon cartilage tissue was filtered through a stack of seven pieces of gauze to remove tissue pieces. The obtained filtrate was passed through a plastic bead column to remove mixed lipids. The eluate from the column was collected and applied to an ultrafiltration apparatus equipped with a membrane having a molecular weight of 1 million cut, and molecules having a molecular weight of 1 million or less were collected as a filtrate. The obtained filtrate was applied to an ultrafiltration apparatus equipped with a membrane having a molecular weight of 100,000 cut to remove molecules having a molecular weight of 100,000 or less. The above steps were repeated as necessary. Salt-saturated ethanol was added to the resulting concentrated solution to precipitate aggrecan. The yield of aggrecan by this method was 1.0% to 2.0%. The yield of aggrecan was expressed as a ratio (%) of the weight of the finally obtained aggrecan to the total weight of salmon nasal cartilage as a starting material.

The degree of purification of the obtained aggrecan was confirmed by HPLC and cellulose acetate membrane electrophoresis. The conditions for HPLC analysis are shown below.
Column: TOSOH TSK-gel G5000P-WXL column + TSK guard column (manufactured by Tosoh Corporation)
Elution: 0.2M NaCl
Flow rate: 0.5 mL / min 30 ° C
Detection: UV-VIS detector (215 nm)

<Preparation of eggplant extract>
All the following operations were performed aseptically. 1 kg of coconut seeds were transferred to a 4 L glass container, 200 mL of 60% ethanol was added and shaken sufficiently, and then immersed for 1 hour at room temperature. After adding 300 mL of sterilized distilled water and shaking sufficiently, it was immersed for 1 day at room temperature. The ethanol concentration at this time is about 24%. Thereafter, the seed was removed by filtration, and the filtrate was recovered (filtrate 1). To the remaining seeds, 500 mL of 24% alcohol was added, shaken sufficiently, and then immersed at room temperature for 1 day. Thereafter, the seed pieces were removed by filtration, and the filtrate was collected (filtrate 2). The filtrates 1 and 2 were combined into an eggplant (seed) extract and stored at 4 ° C. To the remaining seed pieces, 500 mL of 10-20% ethanol was added and extracted for the third time. Extraction was performed for 3 to 7 days in the dark at room temperature with occasional shaking. Thereafter, the seed pieces were removed by filtration, and the filtrate was collected and stored at 4 ° C. (about 500 mL: filtrate 3).

  The above-mentioned eggplant extract and the above 0.1% aggrecan ethanol extract are mixed at the following ratios to adjust the nail-off solution, while the nail-off solution using only the 0.1% aggrecan-ethanol extract is adjusted, and the two are compared. did.

  The alcohol level of the nail-off solution is 5.6%, but it is enough to apply about 0.1 mL (5.6 μL per finger as alcohol) to the fingertip, so there is no worry about irritation (disinfection alcohol spraying Will be much higher alcohol). When the nail-off solution is applied to the fingertip, it is easily dried by body temperature and ambient air in about 1 minute to form a film. This nail-off liquid film protects nails and fingers and prevents invasion from acetone used for nail-off. Therefore, in the product of the present invention, the skin around the nail was not damaged and the gloss of the nail was good compared to the comparative product.

  (C2) A nail art part (fake nail) T having a dish-like vacuum pad P made of a flexible viscous rubber shown in FIGS. 3A and 3B on the back surface was mounted on the nail surface to which the nail-off liquid was applied.
